At least the Russian videos show the true bandwidth of the scope, They maxed out their sinewave generator at 65 mhz and the Hantek was still not 3db down from it's 1 Khz amplitude! I own an OWON HDS3010MN that also has performance well past it's published specs. But I was looking at Hantek before I purchased the OWON, because for the price it is an excellent performer!

This scope looks like something I've been wanting to add to my toolbox at work. I work as an automotive repair technician, and many of the sensors I need to check generate a square wave, or occasionally a sine wave pattern. Also, many components don't use a simple "on / off" voltage. They're pulse width modulated. Not something that you can generally diagnose with just a multimeter. You need a scope to see these signals. Good video. Very informative.

Great review video 👍, I'm considering buying this oscilloscope as my first scope. It's really great how you show all the options and the outside of the device and everything. It may sound silly but this is exactly what is missing in most other review videos, they aren't thorough enough, skipping over the basic functionality of a device, as if that's not the most important part.
Thanks for your appreciation; I'm glad if this device will be your first scope; as for me - it will be the last one at the present moment, as I couldn't find better one so far among the portable scopes, however, I like very much All-Sun EM115A, but this device can't measure current, not to mention maximum frequencies of the scope and the generator. There are really smart guys in All-Sun staff, but the price of the device is not competitive after the birth of 2D42.

Excellent, thorough review. I've been looking for a handheld scope for some automotive diagnostic testing. Pretty basic stuff....cam sensors, crank sensors, and duty cycled solenoids. These are mostly square wave pattern, though I suppose a scope like this could also read CAN bus data. I suppose like any diagnostic device, the best way to learn the ins and outs is to use it on a daily basis and explore the various features.
I bought this one (the 2c42) and it s really good stuff, obviously for the price......i used it everyday in the past month and day by day i learned to appreciated all the functions, it could be the best portable oscilloscope made by Hantek.....
I read in a review on Amazon by a guy who looked into this VERY closely and included photos that it has fuse protection for current reading, but they are very small surface mount ones that are soldered to the board. I have done electronics for about 50 years and blown my share of fuses by forgetting I had leads attached to a meter for measuring current and then placing across a voltage. So, the little diagram on the screen to show you where your leads should be connected might seem overly elementary, but a really good reminder consider you really do NOT want to blow a fuse in this thing.
Thanks, I've been looking for something to check the capacity of my rechargeable batteries so I've ordered the circuit board. I've also ordered a Hantek device. I know it isn't going to be amazing but I think it''ll be good enough for want to do. Thanks again for the video and the information about checking the capacity of rechargeable batteries.

I have only the possibility of use of its own signal generator; but I have no 40 MHz source. As to the device in total - it's really worth buying, as, at least, it works with 10-15-20 MHz signal, it can generate up to 25MHz signal. Besides, it has a very decent multi-meter, which really surprised me. Usually such 3-in-1 devices have multi-meters with poor quality i.e. low accuracy. But this one together with its DSO and SG is a super choice, especially, - in view of its price.
When checking frequency response of the oscilloscope, did you have the probe and Hantek both set to 10x? The probe does not provide the full bandwidth with 1X probe. When probe switch is set to 1X, it limits the bandwidth to 6MHz (see manual page 11).
as someone new to oscilloscopes that does diy i have my choices narrowed to hantek 2c42 handheld or the laptop use hantek 1008c.any suggestions on what to go with?
The capacitor reading seems not accurate but it actually is because caps have a tolerance like resistors. A 10uF with 20% tolerance can read from 8-12uF
Excellent and helpful review. Thank you. Can i ask you a couple of questions please? Q1. Can you think of any reason why soneone should purchase a dso213 which doesnt have built-in BNC connectors (though its 4 channel - 2 analog and 2 digital) and costs about the same price? Q2. What I'm looking for is to buy my very first oscilloscope for automotive and around the house electronics testing. Can you think of a better scope than this one for that purpose?
Hello! A1. The only reason to get dso213 is channel quantity. Of course, BNC connectors are better, but if 2 analog and 2 digital channels are needed, then the purchase of dso213 is reasonable. A2. I really didn't find better device than this one for such purposes. Some time ago I liked JINHAN 2023, but it doesn't have multimeter function; then I've revealed ALL-SUN EM115A, but it has only 1 channel, operates only on its own battery and is more expensive - you can see the review of both devices on my channel. So, the only and the best choice is HANTEK.
@@powerbatterychannel4315 Thank you for replying so quickly. For me the easiest place to purchase it is Amazon, however they only sell it without any oscilloscope probes. Do you have any recommendations for a good quality pair of probes?

Thank you for the review. In my opinion, those scope meters are gimmicks or toys at best. They are not that cheap. On the other hand, proper decent second hand HP Agilent 54501A, 54622D, etc., are only around $100 on ebay.
That was a very good review. I started designing and building BLDC motors at home. Do you think this tool would be suitable for determining the parameters of the motor such as voltage and frequency, etc? Thanks!
Well , A GOOD REVIEW consist not only on throwing out technical data and do a demostration of the item , it must contain if in your opinion is a good item and if it is worth buying it!!!
You want me to find the needle in the hay stack? I am not trying to tell you how to do your videos or reviews BUT a little sentence like " I think that X item is great and worth the money " or " Is not that great dont waste your time with it" will avoid confusion.

Are the two input channels galvanically isolated from each other - e.g. do you have continuity across grounds on the two channels? How about the signal gen - does it share a ground with either or both channels? How about the DMM? Is the USB connector galvanically isolated from all of the above?
Hello, - of course, there is continuity across grounds on the two channels; I've never seen the portable devices with galvanically isolated grounds of two channels. Also, the SG has the same ground as the two channels. USB "-" is grounded in view, most probably, of security reasons. As to the DMM - it's galvanically isolated.
@@powerbatterychannel4315 thanks. Do you have continuity from the USB shield to CH1/CH2/Siggen grounds, or is USB galvanically isolated? This is pretty important to know for a battery operated scope. Some battery operated scopes have galvanically isolated channels, such as e.g. www.tek.com/datasheet/ths700-series. I couldn't find any mention in the spec of the Hantek, so I figured the channels wouldn't be isolated. In a battery-operated instrument without galvanically isolated channels, the instrument's base potential will float to whatever you hook up to the ground, so it's pretty important to know whether other parts of the instrument will float to the same potential. You might say it's crucial safety information, so would be nice to see a followup video with this information... If the probe ground is hooked up to the USB shield (which I fully expect), then that's pretty important to know as well. Imagine hooking a battery operated laptop up to a scope that has a ground lead hooked to line potential. If the USB is not galvanically isolated, you've now lifted the entire laptop to line potential, which it certainly won't be designed for :/. The scope comes with a (10X?) probe that has an isolated BNC connector, but the two other cables have regular BNCs, which seems kind of weird. If you showed the BNC inputs on the scope, I missed it, but it's pretty important safety information to know whether those are recessed or shielded such as to protect against accidental touch on the shields.
@@powerbatterychannel4315 We'd like to know if it is possible to generate the signal while running the osciloscope, like generate a sine to excite a circuit and check the behavior of it with the scope.
@@ElkerCarvalho Yes, it's possible to do it. Moreover, you can generate the signal and measure it with another o-scope, and with this o-scope you can measure the signal of other devices. So, the generator and internal o-scope work independently.
No.... YOUR OPTIONS ARE put the unit into SCOPE mode and use a separate Function Gen to supply the signal that you want to view or Put the unit into AWG mode (function Generator) and use a separate Oscilloscope to view the waveform of the function gen you can't setup a waveform on this unit and then view it with the unit's scope, the 3 main function buttons work independently it would be like saying..... can i watch HDMI 1 and AV 1 on my TV simultaenously.... NO YOU CAN'T they are individual inputs that when switched can only be viewed 1 at a time
that's not really a proper answer (in my opinion) i mean yes, - if you need less than 40MHz in a scope - if you need portability ok here is what i would say (and i have a scope RIGOL DS2032 and i have a Hantek 2D72) and I SAY THIS WITH ALL DUE RESPECT TO POWER BATTERY CHANNEL 1. Portability is great, if you need it (Example, the reason why i bought mine was for work ..... Long story behind it,but basically it's for cabe tracing where a toner fails) so portability is definitely a positive thing 2. analog bandwidth in a scope is like sex, you can never get enough of it . if you can be with a chick for 2hours (200MHz) why would you only take 40mins (40MHz) ? yes.. the speech is.... IT DEPENDS WHAT YOU'RE TESTING and if you know that you will never probe anything above 30MHz then you can use this scope BUT..... THAT'S COMPLETE AND UTTER BULLSHIT because you will go higher ,Everyone does it's definitely a difficult decision when buying a scope (Choosing the bandwidth) and then you have to fit into a budget. for this one, i recommend you get the 2D72 (70MHz Bandwidth) i mean, why would you buy the 40MHz when the 70MHz is a very similar price ? 3. this is definitely NOT the best choice you can make. even if your criteria is no higher than 40MHz and PORTABILITY this is FAR FROM THE BEST CHOICE. 4. in saying that,..... it's good little piece of tech, but it does have it's limitations HERE IS MY REVIEW - The Screen is a shit load smaller than a bench scope, but then again,that's the downfall of a portable scope but then again, other portable scopes do have larger screens BECAUSE THE HANDHELD MODEL IS PHYISCALLY LARGER so... you have that trade off When i was buying my Rigol DS2032A a few years back i had the choice between the DS2000A series and the DS1000E which had a small screen i chose the DS2000A and have never looked back and also , people who chose the DS1000E are now selling them on gumtree ever since the DS1054Z with 4 channels came out CONCLUSION... DS1000E IS SHIT AND EVERYONE KNOWS IT it can do a job.... sure but, You're not going to enjoy your scope for very long. and on the subject of DS1054Z my scope DS2032A (which is unlocked to 300MHz) still.. years later, shit all over the 1054Z other than my scope has 2 inputs andthe 1054Z has 4 my scope, SPEC FOR SPEC is still far better so..... you gotta look at what you're getting - this is a basic low level scope, it's DMM function is a bitoff, but it's good, - it's waveform function is limited in how much amplitude you can use and depending on the waveform you choose, how high a frequency you can go to - the functions are very basic and TAKE SOME GETTING USED TO - The Refresh rate of the scope is not that great due to lack of decent memory size so.... YOUR QUESTION WAS, WOULD I RECOMMEND THIS OVER A *REGULAR* BENCH SCOPE ANSWER : NO... NOT A FUCKING HOPE IN THE WORLD first of all a bench scope - Has Knobs (potentiometers) that you can turn very quickly , this one is difficult to navigate BY COMPARISON - a bench scope has math functions ,this does not (yes i know in the software it does, but PORTABILITY ..... Remember, if you're hooking it up to a pc it'snot portableanymore - a Bench scope has Deeper memory Depth - it has Better Resolution - Bigger Screen - some have record functions - Easier controls layout you can't replace a bench scope with a portable scope this little unit (like any equipment )has a time and a place, but it's far from being your best option i also don't like the colors that were chosen on the screen, example THE PURPLE is shit and makes things hard to read, especially with the small font size so ... think about all that ok also, i agree with Power Battery Channel, the Multimeter is nice it shows you where to connect your probes the numerical display is big and easy on the eyes the DMM is a little out, but nothing to get pissy about , all in all it's ok
don;t by the same model he is using a 2D42 which means that scope that the scope has a 40MHz analog bandwidth on the input. buy the 2D72 which has a 70MHz analog bandwidth input why not, the prices are very similar
NO IT'S NOT the unit has 3 function buttons SCOPE DMM AWG (Function Generator) you can't use any of them while using the other one example, you can't access DMM while using SCOPE you can't access AWG while using SCOPE if you try, you'll just jump into AWG mode and out of SCOPE mode i'm not sure why the OP said yes of course
@@powerbatterychannel4315 hi mate, are you sure about that ???? if you are in SCOPE mode and you press AWG IT LEAVES THE SCOPE FUNCTION and while in AWG there is no menu option to access scope function you can't use one mode while using the other so.. why did you say YES OF COURSE ?
@@martinkuliza Watching the video I understood that he was using function generator and scope at the same time, actually introducing itself the signal...
@@pueser9295 well. if he's using an EXTERNAL Function gen while the unit was in Scope Mode then.. why does he ask the question ? this should be common sense, of course you can do that it's like asking , can i make a cup of coffee while viewing the waveform on my Scope. that's should be common sense i thought he meant can you use the internal AWG to feed a signal into the internal Scope
Very good video and good explanation about its operation, I have only one doubt left, in the instructions it says that maximum 150 Vrms, but that supports x100 probes, could be used in 230 V / 400 VRms with an x100 probe and that the equipment does not break down, and also between different phases, or would it need a differential probe? Thanks beforehand for your attention.
In case of 230 V / 400 VRms you should use only x100 probe. Some users use even x10 probe, but it may damage the equipment, not to mention the fact that they will not be able to see the whole graph.
At the end of the video, you connect the oscilloscope to the PC. With a voltage battery test, we saw on the PC screen voltage change in volt unit, but it is also indicated in graphic ac positive/negative variation on bottom of the PC screen. That information seem to be recorded on the PC for later use, is that graphic form option is offert on the oscilloscope screen...Something like a record signal mode? Or I need to be online with a PC...?
I don't remember; however, there is a button "Save", so, you can save all the data to the corresponding file. As to the graphic form itself - as I know, there is no option to record and save it.
Nice video, it helping a lot of people in to making an educated decision, thanks for the effort you put in to it. I still have a question, the oscilloscope is able to plot in XY mode?
@Seamus O'Dork THE SOFTWARE is called "Hantek 2000 Ver 1.1.11" (Current Version, to my knowedge) it can be downloaded directly from hantek HERE www.hantek.com/en/PagesFW_Vyyrj_4.html IMPORTANT NOTE : Select "HANTEK 2D82 SOFTWARE" it's the same for all the models i have a 2D72 and it works just fine
Thanks for the video! I have a quick question - can you somehow see the voltage changes graph on the multimeter itself? It's an important feature for me and i'm trying to decide if i'm gonna buy this meter or not. Thanks!
www.eevblog.com/forum/testgear/hantek-2c422c722d422d72/ Product page: hantek.com/en/ProductDetail_13174.html It tends to be sold as one of 4 models: 2C42/2C72/2D42/2D72 'C' means 2 channel scope and DMM. 'D' means 2 channel scope, DMM and AWG. '4' means 40MHz. '7' means 70Mhz.
Did I get it right that this device can't show forms of voltage and/or current directly from DMM? In other words, DSO and DMM are actually two different devices just sharing the same case, keyboard and display?
my model.. 2D72 has 3 primary functions SCOPE - 70MHz Scope, 3k / 6k Memory depth, 2 Channel DMM - Multimeter for Continuity , Resistance, V DC, mV DC, V AC, Amps DC, mA DC, Amps AC, mA AC, Diode, Capacitance AWG - Waveform Generator all of the Voltage forms are show directly from the DMM function but you then have to switch to either SCOPE Or AWG you can't display AWG or DMM at the same time actually you can't display AWG, DMM OR SCOPE in any combination with each other at the same time but, while in DMM mode, you can certainly measure all of the above forms of voltage in that mode, no problem as well as capacitance , diode, continuity etc NOTE : the continuity function is not the best it works, but it's sensitive and response is pretty fucked in my opinion.
Even showing waveforms correctly; My Hantek 2D42 measures electrical (numerical) values wrong, i wonder if there are mini pots to correct it inside it...
It would be nice if you can tell us what is the smallest AC voltage in mV it can measure accurately. From the display, looks it could handle up to 1 mV. But accuracy?

@@mirzageeelectronic999 You can't. Mustool is a grandson of EONE ET201, which has this function. But Hantek is a more professional device, which uses o-scope probes for these needs.
It doesn't meter how it is Mustool or Hantek. I just want to measure AC 220V waveform and DC high frequency voltage like chopper transformer voltage or FET gate voltage. Etc How my choice is Hantek I like it. But problem is I mention above.
Yes, for BASIC electronics repair.... it's ok the DMM will be fine for electronics repair the DSO is on the very basic end and will end up being a pain in the arse for electronics repair you can use it , TO A DEGREE, but you'll see it gets to be a pain when you're troubleshooting and then have to search for that menu option in saying that THE UNIT HAS PROFILES YOU CAN SAVE YOUR PREFERRED SETTINGS IN consider that as well
I think I’m gonna use one of these for some off the bench work I may have time to time, but on the upside I want probably a fluke brand that can/will replace my current DMM (Fluke 115) with the current features/functions plus the DSO as addition. For price, an affordable fluke with DSO would direct me to used and monochrome dot matrix screen. As a person whom I regard(love your channel and your reviews), what would be the cheapest color screen fluke DSO with MM. or regardless of the Hantek, what could be your choice on the affordable side of a more professional tool?
Fluke 115 is really a good device, however, I didn't compare is with Hantek. On the other side, Hantek has really decent accuracy: ua-cam.com/video/kHDpdZMFMXg/v-deo.html And, finally, - I've had also All-Sun EM115A, - but Hantek is much better, the DSO frequency is higher and also it can measure amps unlike EM 115A. So, Hantek is really a universal device; moreover, it has 2 channels.
@@prmusicoficial It seems in this mode the device measures only maximum; moreover, when you have amp=2V in signal generator mode, the oscilloscope mode indicates amp=4V, but in fact it's not the amplitude, it's peak-to-peak voltage.

What’s the difference with the 40hz and the 70hz (I already know the models separate by AWG and Non-AWG)? Is the higher hz more speed? More accuracy or reliability?
Hi, Would you mind checking something for me on your Hantek 2D72: I recently purchased one and am seeing a couple of issues with mine; it would be helpful to know if your unit has these same issues, or if it is just mine (in which case I will return for a replacement.) The issues in question: • Periodic display glitching (even when paused) • Holding down arrow keys to scroll, stops and starts over at slow speed every 5 seconds So if you could: are you seeing these same issues with your 2D72? Which firmware version are you on? Some more info: this video shows the issues with mine: ua-cam.com/video/rjSrT5m2_Kk/v-deo.html Many thanks! Phil
Hello, the problems you describe may be not so serious, I mean a replacement may not take place, but - my device definitely didn't have such behavior; so, it's not normal anyway...
Power Battery Channel Thanks! I do like the features of the unit; it works well besides the glitches which can be annoying but don’t prevent it from being used successfully.
the Continuity function is shit , let's just put it that way it works, but it's not very responsive , you really need to hold the probes down for a bit its not fast as for resistance , it takes a second or so
Why would you ever turn on the bandwidth limiter, (20 Mhz in that scope), when you were checking the frequency response of the scope?.......What you ended up checking was the performance of the bandwidth limiter! Same problem when you were demonstrating how cleanly it could reproduce squarewave signals? Most 2C42 devices are flat to over 40 MHz and only 3DB down at 60 MHz. The 2D22 uses the exact same vertical amplifiers so the bandwidth of both scopes should be the same. You did Hantek a great disservice in your video because most people purchase that device for it's oscilloscope capabilities and your video made those capabilities look awful! I really think that you need to update (or add a correction at the end of), your video to show the true bandwidth of the vertical amplifiers in that device!
It was difficult to find a video on this in English. Awesome job! Thank you for taking the time to make this and I see you have a lot of similar content. I have subscribed!
You are welcome!
At least the Russian videos show the true bandwidth of the scope,
They maxed out their sinewave generator at 65 mhz and the Hantek was still not 3db down from it's 1 Khz amplitude!
I own an OWON HDS3010MN that also has performance well past it's published specs.
But I was looking at Hantek before I purchased the OWON, because for the price it is an excellent performer!
I do not own a Hantek anything but I believe they deserved to be tested more accurately......

I read in a review on Amazon by a guy who looked into this VERY closely and included photos that it has fuse protection for current reading, but they are very small surface mount ones that are soldered to the board. I have done electronics for about 50 years and blown my share of fuses by forgetting I had leads attached to a meter for measuring current and then placing across a voltage. So, the little diagram on the screen to show you where your leads should be connected might seem overly elementary, but a really good reminder consider you really do NOT want to blow a fuse in this thing.

Works ok. Use it in our car workshop. I tried to scope camsensor and it worked excelent.
What's it like for scrolling and zooming into a stored pattern? I also want one for automotive work.
excellent review
Do you think it is worth while buying?
Have you testing the bandwidth of the oscilloscope?
I have only the possibility of use of its own signal generator; but I have no 40 MHz source. As to the device in total - it's really worth buying, as, at least, it works with 10-15-20 MHz signal, it can generate up to 25MHz signal. Besides, it has a very decent multi-meter, which really surprised me. Usually such 3-in-1 devices have multi-meters with poor quality i.e. low accuracy. But this one together with its DSO and SG is a super choice, especially, - in view of its price.
Terrific...keep it up, Thanks v much....Great job.
You are welcome
Thanks for the excellent and comprehensive review!
Can frequency be measured with the DMM function, or only with the oscilloscope?
When checking frequency response of the oscilloscope, did you have the probe and Hantek both set to 10x? The probe does not provide the full bandwidth with 1X probe. When probe switch is set to 1X, it limits the bandwidth to 6MHz (see manual page 11).
Thanks; as I remember, the probe switch was set to 1X.
Wow fantastic review!!
as someone new to oscilloscopes that does diy i have my choices narrowed to hantek 2c42 handheld or the laptop use hantek 1008c.any suggestions on what to go with?
The capacitor reading seems not accurate but it actually is because caps have a tolerance like resistors. A 10uF with 20% tolerance can read from 8-12uF
Excellent and helpful review. Thank you. Can i ask you a couple of questions please?
Q1. Can you think of any reason why soneone should purchase a dso213 which doesnt have built-in BNC connectors (though its 4 channel - 2 analog and 2 digital) and costs about the same price?
Q2. What I'm looking for is to buy my very first oscilloscope for automotive and around the house electronics testing. Can you think of a better scope than this one for that purpose?
Hello!
A1. The only reason to get dso213 is channel quantity. Of course, BNC connectors are better, but if 2 analog and 2 digital channels are needed, then the purchase of dso213 is reasonable.
A2. I really didn't find better device than this one for such purposes. Some time ago I liked JINHAN 2023, but it doesn't have multimeter function; then I've revealed ALL-SUN EM115A, but it has only 1 channel, operates only on its own battery and is more expensive - you can see the review of both devices on my channel. So, the only and the best choice is HANTEK.
@@powerbatterychannel4315 Thank you for replying so quickly.
For me the easiest place to purchase it is Amazon, however they only sell it without any oscilloscope probes. Do you have any recommendations for a good quality pair of probes?

Thank you for the review. In my opinion, those scope meters are gimmicks or toys at best. They are not that cheap. On the other hand, proper decent second hand HP Agilent 54501A, 54622D, etc., are only around $100 on ebay.
The question is that HP Agilent is not portable.

Thanks! I'm not sure, but it should be suitable.
Well , A GOOD REVIEW consist not only on throwing out technical data and do a demostration of the item , it must contain if in your opinion is a good item and if it is worth buying it!!!
Then, please, revise the review once more and you will definitely find out how I'm pleased with this device :)
You want me to find the needle in the hay stack? I am not trying to tell you how to do your videos or reviews BUT a little sentence like " I think that X item is great and worth the money " or " Is not that great dont waste your time with it" will avoid confusion. By the way , other viewer asked you the same question directly "Did you like it"? and you answered " Sure" so what does that tells you about your video? Dont get me wrong , IT IS A GREAT VIDEO.
Are the two input channels galvanically isolated from each other - e.g. do you have continuity across grounds on the two channels? How about the signal gen - does it share a ground with either or both channels? How about the DMM? Is the USB connector galvanically isolated from all of the above?
Hello, - of course, there is continuity across grounds on the two channels; I've never seen the portable devices with galvanically isolated grounds of two channels. Also, the SG has the same ground as the two channels. USB "-" is grounded in view, most probably, of security reasons. As to the DMM - it's galvanically isolated.
@@powerbatterychannel4315 thanks. Do you have continuity from the USB shield to CH1/CH2/Siggen grounds, or is USB galvanically isolated? This is pretty important to know for a battery operated scope. Some battery operated scopes have galvanically isolated channels, such as e.g. www.tek.com/datasheet/ths700-series. I couldn't find any mention in the spec of the Hantek, so I figured the channels wouldn't be isolated. In a battery-operated instrument without galvanically isolated channels, the instrument's base potential will float to whatever you hook up to the ground, so it's pretty important to know whether other parts of the instrument will float to the same potential. You might say it's crucial safety information, so would be nice to see a followup video with this information... If the probe ground is hooked up to the USB shield (which I fully expect), then that's pretty important to know as well. Imagine hooking a battery operated laptop up to a scope that has a ground lead hooked to line potential. If the USB is not galvanically isolated, you've now lifted the entire laptop to line potential, which it certainly won't be designed for :/.
The scope comes with a (10X?) probe that has an isolated BNC connector, but the two other cables have regular BNCs, which seems kind of weird. If you showed the BNC inputs on the scope, I missed it, but it's pretty important safety information to know whether those are recessed or shielded such as to protect against accidental touch on the shields.
The USB shield has no continuity to CH1/CH2/Siggen grounds.
Hello there, great video, are you able to see the oscilloscope while you are using the function generator?
Hello, do you mean both application on the display at the same time? Or just see the graph of the generator with the help of this o-scope?
@@powerbatterychannel4315 We'd like to know if it is possible to generate the signal while running the osciloscope, like generate a sine to excite a circuit and check the behavior of it with the scope.
@@ElkerCarvalho Yes, it's possible to do it. Moreover, you can generate the signal and measure it with another o-scope, and with this o-scope you can measure the signal of other devices. So, the generator and internal o-scope work independently.
No.... YOUR OPTIONS ARE
put the unit into SCOPE mode and use a separate Function Gen to supply the signal that you want to view
or
Put the unit into AWG mode (function Generator) and use a separate Oscilloscope to view the waveform of the function gen
you can't setup a waveform on this unit and then view it with the unit's scope,

@@martinkuliza So I can't test guitar amplifier using only one device (2D42) - by generating signals and check them on osc ?
Great video, i do have a question: would you recommend this handheld oscilloscope over a regular oscilloscope?
In case you need portability and the device at 40Mhz or less, including a very decent multimeter - sure; it's the best choice.
@@powerbatterychannel4315 okay! thank you :D
You are welcome)
that's not really a proper answer (in my opinion)
i mean yes,
- if you need less than 40MHz in a scope
- if you need portability
ok
here is what i would say (and i have a scope RIGOL DS2032 and i have a Hantek 2D72)
and I SAY THIS WITH ALL DUE RESPECT TO POWER BATTERY CHANNEL
1. Portability is great, if you need it (Example, the reason why i bought mine was for work ..... Long story behind it,but basically it's for cabe tracing where a toner fails) so portability is definitely a positive thing
2. analog bandwidth in a scope is like sex, you can never get enough of it .
if you can be with a chick for 2hours (200MHz) why would you only take 40mins (40MHz) ?
yes.. the speech is.... IT DEPENDS WHAT YOU'RE TESTING and if you know that you will never probe anything above 30MHz then you can use this scope
BUT..... THAT'S COMPLETE AND UTTER BULLSHIT because you will go higher ,Everyone does
it's definitely a difficult decision when buying a scope (Choosing the bandwidth) and then you have to fit into a budget.
for this one, i recommend you get the 2D72 (70MHz Bandwidth) i mean, why would you buy the 40MHz when the 70MHz is a very similar price ?
3. this is definitely NOT the best choice you can make.
even if your criteria is no higher than 40MHz and PORTABILITY this is FAR FROM THE BEST CHOICE.
4. in saying that,..... it's good little piece of tech, but it does have it's limitations
HERE IS MY REVIEW
- The Screen is a shit load smaller than a bench scope, but then again,that's the downfall of a portable scope but then again, other portable scopes do have larger screens BECAUSE THE HANDHELD MODEL IS PHYISCALLY LARGER so... you have that trade off
When i was buying my Rigol DS2032A a few years back i had the choice between the DS2000A series and the DS1000E which had a small screen
i chose the DS2000A and have never looked back and also , people who chose the DS1000E are now selling them on gumtree ever since the DS1054Z with 4 channels came out
CONCLUSION... DS1000E IS SHIT AND EVERYONE KNOWS IT
it can do a job.... sure but, You're not going to enjoy your scope for very long.
and on the subject of DS1054Z my scope DS2032A (which is unlocked to 300MHz) still.. years later, shit all over the 1054Z other than my scope has 2 inputs andthe 1054Z has 4 my scope, SPEC FOR SPEC is still far better
so..... you gotta look at what you're getting
- this is a basic low level scope, it's DMM function is a bitoff, but it's good,
- it's waveform function is limited in how much amplitude you can use and depending on the waveform you choose, how high a frequency you can go to
- the functions are very basic and TAKE SOME GETTING USED TO
- The Refresh rate of the scope is not that great due to lack of decent memory size
so.... YOUR QUESTION WAS, WOULD I RECOMMEND THIS OVER A *REGULAR* BENCH SCOPE
ANSWER : NO... NOT A FUCKING HOPE IN THE WORLD
first of all a bench scope
- Has Knobs (potentiometers) that you can turn very quickly , this one is difficult to navigate BY COMPARISON
- a bench scope has math functions ,this does not (yes i know in the software it does, but PORTABILITY ..... Remember, if you're hooking it up to a pc it'snot portableanymore
- a Bench scope has Deeper memory Depth
- it has Better Resolution
- Bigger Screen
- some have record functions
- Easier controls layout
you can't replace a bench scope with a portable scope
this little unit (like any equipment )has a time and a place, but it's far from being your best option
i also don't like the colors that were chosen on the screen, example THE PURPLE is shit and makes things hard to read, especially with the small font size
so ... think about all that ok
also, i agree with Power Battery Channel, the Multimeter is nice
it shows you where to connect your probes
the numerical display is big and easy on the eyes
the DMM is a little out, but nothing to get pissy about , all in all it's ok
Thanks for this review, it is helpful as I'm thinking about buying the same model.
You are welcome!
don;t by the same model
he is using a 2D42 which means that scope that the scope has a 40MHz analog bandwidth on the input.
buy the 2D72 which has a 70MHz analog bandwidth input
why not, the prices are very similar
Execllent! and I want to ask you something. Is it possible to use a function generator and oscilloscope at the same time??
Yes, of course.
NO IT'S NOT
the unit has 3 function buttons
SCOPE DMM AWG (Function Generator)
you can't use any of them while using the other one
example, you can't access DMM while using SCOPE
you can't access AWG while using SCOPE if you try, you'll just jump into AWG mode and out of SCOPE mode
i'm not sure why the OP said yes of course
@@powerbatterychannel4315
hi mate, are you sure about that ????
if you are in SCOPE mode and you press AWG
IT LEAVES THE SCOPE FUNCTION
and while in AWG there is no menu option to access scope function
you can't use one mode while using the other so.. why did you say YES OF COURSE ?
@@martinkuliza Watching the video I understood that he was using function generator and scope at the same time, actually introducing itself the signal...
@@pueser9295
well. if he's using an EXTERNAL Function gen while the unit was in Scope Mode
then.. why does he ask the question ?
this should be common sense, of course you can do that
it's like asking , can i make a cup of coffee while viewing the waveform on my Scope.
that's should be common sense
i thought he meant can you use the internal AWG to feed a signal into the internal Scope
Very good video and good explanation about its operation, I have only one doubt left, in the instructions it says that maximum 150 Vrms, but that supports x100 probes, could be used in 230 V / 400 VRms with an x100 probe and that the equipment does not break down, and also between different phases, or would it need a differential probe?
Thanks beforehand for your attention.
In case of 230 V / 400 VRms you should use only x100 probe. Some users use even x10 probe, but it may damage the equipment, not to mention the fact that they will not be able to see the whole graph.
@@powerbatterychannel4315
thanks for your answer
How fast of a scope do you need to measure spi data and apa102 addressable led data?
At the end of the video, you connect the oscilloscope to the PC. With a voltage battery test, we saw on the PC screen voltage change in volt unit, but it is also indicated in graphic ac positive/negative variation on bottom of the PC screen. That information seem to be recorded on the PC for later use, is that graphic form option is offert on the oscilloscope screen...Something like a record signal mode? Or I need to be online with a PC...?
I don't remember; however, there is a button "Save", so, you can save all the data to the corresponding file. As to the graphic form itself - as I know, there is no option to record and save it.
Nice video, it helping a lot of people in to making an educated decision, thanks for the effort you put in to it. I still have a question, the oscilloscope is able to plot in XY mode?
No, but math functions are available in the software, including FFT.

Hello, have you seen the video till the end? The computer software shows the graph, but not the multimeter.
What kind of Diode was that, 38 mV forward voltage?!
It was an old Soviet diode 'D305'
Germanium high-current rectifier
www.eevblog.com/forum/testgear/hantek-2c422c722d422d72/
Product page:
hantek.com/en/ProductDetail_13174.html
It tends to be sold as one of 4 models: 2C42/2C72/2D42/2D72
'C' means 2 channel scope and DMM.
'D' means 2 channel scope, DMM and AWG.
'4' means 40MHz.
'7' means 70Mhz.
Did I get it right that this device can't show forms of voltage and/or current directly from DMM?
In other words, DSO and DMM are actually two different devices just sharing the same case, keyboard and display?
I'd like to know it also
my model.. 2D72 has 3 primary functions
SCOPE - 70MHz Scope, 3k / 6k Memory depth, 2 Channel
DMM - Multimeter for Continuity , Resistance, V DC, mV DC, V AC, Amps DC, mA DC, Amps AC, mA AC,
Diode, Capacitance
AWG - Waveform Generator
all of the Voltage forms are show directly from the DMM function
but you then have to switch to either SCOPE Or AWG
you can't display AWG or DMM at the same time actually you can't display AWG, DMM OR SCOPE in any combination with each other at the same time
but, while in DMM mode, you can certainly measure all of the above forms of voltage in that mode, no problem
as well as capacitance , diode, continuity etc
NOTE : the continuity function is not the best
it works, but it's sensitive and response is pretty fucked in my opinion.
Even showing waveforms correctly; My Hantek 2D42 measures electrical (numerical) values wrong, i wonder if there are mini pots to correct it inside it...
I read that it's caused by bad solder joints on some resistors on the first stage of DMM.
It would be nice if you can tell us what is the smallest AC voltage in mV it can measure accurately. From the display, looks it could handle up to 1 mV. But accuracy?
I haven't this device; you can ask someone who has recently reviewed it.
really good
Could this be used to check capacitor polarity?
I don't think so.

Hi,
Would you mind checking something for me on your Hantek 2D72: I recently purchased one and am seeing a couple of issues with mine; it would be helpful to know if your unit has these same issues, or if it is just mine (in which case I will return for a replacement.)
The issues in question:
• Periodic display glitching (even when paused)
• Holding down arrow keys to scroll, stops and starts over at slow speed every 5 seconds
So if you could: are you seeing these same issues with your 2D72? Which firmware version are you on?

buzzer and resistance how fast is it you were too vague
Let's say, it's pretty fast; I'm pleased with it.
the Continuity function is shit , let's just put it that way
it works, but
it's not very responsive , you really need to hold the probes down for a bit
its not fast

Why would you ever turn on the bandwidth limiter, (20 Mhz in that scope), when you were checking the frequency response of the scope?.......What you ended up checking was the performance of the bandwidth limiter!
Same problem when you were demonstrating how cleanly it could reproduce squarewave signals?
Most 2C42 devices are flat to over 40 MHz and only 3DB down at 60 MHz.
The 2D22 uses the exact same vertical amplifiers so the bandwidth of both scopes should be the same.
You did Hantek a great disservice in your video because most people purchase that device for it's oscilloscope capabilities and your video made those capabilities look awful!
I really think that you need to update (or add a correction at the end of), your video to show the true bandwidth of the vertical amplifiers in that device!
Totally worthless. Do not buy this.
