I cant believe I have not come across these videos b4 now! Love these videos. He's just geeky enough to believe what he is saying and not so geeky to be boring or off putting. Blunt honesty is refreshing. Keep it up!
May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you may your heart be strong. May you find what you're seeking wherever you roam
Great accent...Good information especially explaining sampling rate and memory depth. The guy is always pushing certain brands. I had a RIGOL and it was a mess & I returned it. Supposedly it was missing the latest firmware update but I don't need the grief. Plus it was more expensive than other Chinese brands. I have an ATTEN and HANTEK & have found both to be terrific and they were less cost than the RIGOL I returned.
@carnews333 Yes, you need an oscilloscope if you are into electronics. No, you don't need to spend $10,000. A $350 Rigol will do you just fine. $50 ebay 20MHz dual channel analog will also do you just fine.
I bought a Tektronix 2247A scope for my first scope but, it didn't work. The CRT works perfect on it & I'm hoping to get the thing fixed eventually! So I bought a new Siglent SDS 1102CML+. Turns out that It is officially my first (working) scope now. It's a total nightmare trying to figure the damn thing out! I feel like I need to take a complete course on how to properly run it. Thank God there's an automatic trigger button & I do know how to zoom in and zoom out. I do know how to compensate the probe/s. I was able to look at the noise of my switching adjustable DC power supply DP305A. Buck converter. I was experimenting with a small capacitor trying to take the ripple away. I found out when you move the probes farther away from the capacitor, it stoppes working & the Ripple will come back. so I'm not quite sure how to filter the Ripple coming out of the switching power supply permanently unless you put a filter capacitor right there on the breadboard by the ripple? Electricity reminds me of a roaring river moving Through the Wires splashing back and forth in the wires. The capacitor slows it down right there around it but, as soon as you get further Downstream from the capacitor, it starts splashing around again. I don't know? I'm a newbie. is that kind of how it works?
Finally we got the Oscilloscope video, lets have more examples on the screen comparing two oscilloscopes....... real good.........more oscilloscope videos please......
I started following you 9 years ago starting from this video! I miss the old garage days! :) 1200 or so videos later and I'm still watching. Keep it up!
@gotaimabara You are taking my comment out of context. I was talking about the small sample memory in the lowest cost "cheap" Tektronix scopes. I did not mean "cheap" as in quality. Yes, the Rigol is better value for money than the equivalent Tektronix scope for most beginners.
@gotaimabara You're forgetting that RIGOL makes some of the oscilloscopes for Agilent, whereas most of these no-name Chinese multimeters are just that: cheap no-name Chinese multimeters. If we could verify that some brand of Chinese multimeter were equivalent to a high-quality brand, then by all means we would go for it.
Hi David, I've following all your blogs and I really enjoy it! I have one suggestion for you, it would be possible if you post step by step how to use an oscilloscope? For beginners like me! I finally bought the Hantek DSO 1060 and hope works for small electronic projects. Regards, Gustavo
Dave,, you do know that if you shipped everything in your workshop you dont need or use to me, you would have much more room in your place to put better kit from more garage sales etc. Just think how awesome that would be and how much fun you could have, we could also see you open the boxes and have fun. Sounds good to me.
You should do a more in-depth tutorial about oscilloscopes in general. Now I know about trigger hold-off but what else? Afrotechmods has a tutorial but it's very basic and I have figured all of that out already.
I personally use the HP 54200D for my needs. Yep it's old but it works fine plus has a little bit of a LogAn so I don't have to drag out my old HP 16500B.
@jewishcrimenetwork They are different beasts. The Rigol is a more versatile instrument for general use, as it offers (poor compared to the 2246) analog performance, and single shot digital sampling the 2246 doesn't have.
Lawrence Lederer You have to take Dave with a grain of salt. Good info, take the factual stuff, ignore his opinions. Much like any University professor.
I just have to reply, Dave states that Tektronix suggest sampling of 2.5x or 5x when in fact the entry oscilloscopes sample at the same as the Rigol he had in his hand. It is obvious how anti Tektronix he is... One should really take what he says with a grain of salt...
Considering you can easily do the firmware upgrade to the Rigol DS1052 to upgrade it per the video instruction here, I'd bet it's much better to buy the Rigol.
I'm very happy for your video. I'm very beginner in oscilloscope. I wonna buy a oscilloscope that will measure high frequency like 2 or 3 GHz. Now question is that If i buy a oscilloscope with size of 1G Digital Storage Oscilloscope 100MHz bandwidth, will it be able to measure the high frequency. If it doesn't than which oscilloscope is suitable for me?
Measuring high frequency signals is difficult. A scope that you have chosen will be blind to signal completely. A $40000 Tek DPO7000C will be able to measure the signal, but considering the capacitive loading of the probe, you will not be able to trust the result completely. What kind of signal? What kind of conclusions do you need to make on it? If heterodyne probe adapter is an option, you can use a cheap scope too.
ive noticed that on DSO's they have a usb port on the front is this a way of increasing the memory depth ?? might be a stupid Q but ive only just begun looking at scopes and lecy stuff in gen watched many of ur vids on scopes and the have been very informative and well constructed thanx for all the posts ;)
Hi dave i want to know is it really necessary to spend 10,000 U.S.A dollars on a oscilloscope for a regular person in computer engineering. Also, I'm still in High School and i'm learning small things about of computer engineering. So, do you think an oscilloscope is necessary for me right now?
Sir what should I expect to spend on a oscilloscope, I just buy and sell stuff and would like to check stuff I buy, not on a big scale, just the odd thing, can you please give me an approximate price and model, like I said it can be very basic but would love to hear from the guru himself, thank you very much fr9m Canada.
'Won' an HP54201A digitizing scope for $83 to my door on ebay. Specs say- 'Dual 200 mega sample/ second allowing 50MHz single shot wave form capture.' I am repairing electronic (musical) organs for recirculation into the community. With the advent of Craigslist the market is flooding with low dollar organs that were once high dollar. Most are analog transistor oscillator card ( personal favorite ala' Ray Manzarek), opamp based. Save for tone wheel Hammonds, tubes are rare. Is this scope OK?
is the Rigol DS1052E Digital Oscilloscope 50MHz 1 GSa/sec 2 channels plus USB storage a good one for working with tesla coils work and things around that leval
It depends on what you want o measure and at which frequency. For example, if you want to make music with your tesla coils and measure the frequency, it will be good enough. Because the sound frequency we are able to hear goes only to around < 20 KHz and the typical low cost soundcard has only a frequency of 48-96 KHz, thus a 50 MHz Oscillosckope with 1 GSA/s will be more than adequate. With a sample at a frequency of 96 KHz you will be able to achive 10416 samples per waveform with this Oscilloscope. That is more than plenty enough. The formula is 1000^3 SA/s / 96*1000 Hz = 10416 samples On the other side, with only 1 Million measuring points, you might be able to sample only 1*1000^2 /201416 samples = 96 waveforms at that resolution. If you decrease the resolution, which means storing less samples per waveform, the number of waveforms or duration increases.
well i watched the first half and it missed some major questions i have, i shall try the second half video instead, but i think it missed a load of beginneres questions
@JRogue250 if he was biased he wouldn't point out the flaws in these things. you really need to watch more of his videos to realize that a. he knows what he's talking about and b. if something is crap he will say it's crap and I really doubt that a paid biased advertiser would point out the fact you can buy the cheaper one and hack it to get the more expensive one for no extra cost.
@gotaimabara The oscilloscope equivalent to a cheap chinese meter is this: 2 Channel PC Computer Digital mini USB Oscilloscop Operating systems used: W2K, XP ,Windows 7(32bit) Signal input: BMC connection with universal oscillograph probe Max sampling: 8kHz x 1/ (4kHz x 2) Measurable frequency: 0Hz -----3kHz DIV array: horizontal 16DIV x vertical 10DIV Max voltage: 0---5V Error of voltage measurement: ±30mV Adjustable range of time domain: 10 mS/DIV----10800 S/DIV Go search Ebay for it.
Oh come on man. "Cheap scopes like Tektronix"? They cost 10 times more because they are 10x better. Rigol is a knock off they ripped from the contract work they do for Agilent. Perhaps the Rigol is not that bad for the price and you're trying to convey that message. But it's coming across as a biased Rigol infomercial. You then post: "There is an ad on my eevblog dot com website for the Rigol from an Australian supplier, only $399. Tell'em I sent you.". No biased, eh?
I cant believe I have not come across these videos b4 now! Love these videos. He's just geeky enough to believe what he is saying and not so geeky to be boring or off putting. Blunt honesty is refreshing. Keep it up!
Dude, you really are the best. I love you videos and love your humor. Thanks for helping all of us folks trying to find our way through this stuff.
He is so happy on this old video.
May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you may your heart be strong. May you find what you're seeking wherever you roam
It really means nothing if you just say such things to random people that you don't know.
Assalamualykum dear brother, praying for anyone is not needed to know him.
but if it's not needed to know him who are you praying for?

@JRoque250 Yes, I am completely unbiased, and am famous for it in fact. I shot this video WAY before I got supplier ads on my website.
@gotaimabara You are taking my comment out of context. I was talking about the small sample memory in the lowest cost "cheap" Tektronix scopes. I did not mean "cheap" as in quality.
Yes, the Rigol is better value for money than the equivalent Tektronix scope for most beginners.
Watched in 2012. I miss these educational tutorials.
Thank you Dave. Helped me a lot with looking for a nice used dso. I got a lot for the money.
@gotaimabara You're forgetting that RIGOL makes some of the oscilloscopes for Agilent, whereas most of these no-name Chinese multimeters are just that: cheap no-name Chinese multimeters.

What happened to sound and motion, they aren't synchronized. Check it out!
Because it is #13 ;)
Dave,, you do know that if you shipped everything in your workshop you dont need or use to me, you would have much more room in your place to put better kit from more garage sales etc. Just think how awesome that would be and how much fun you could have, we could also see you open the boxes and have fun. Sounds good to me.
Haha that would be Realy awesome! :D
Update, you can use the hantek 6022be with windows 8, have to download a driver from there website.
You should do a more in-depth tutorial about oscilloscopes in general. Now I know about trigger hold-off but what else? Afrotechmods has a tutorial but it's very basic and I have figured all of that out already.
I personally use the HP 54200D for my needs. Yep it's old but it works fine plus has a little bit of a LogAn so I don't have to drag out my old HP 16500B.
I have the same Rigol scope really good quality,
So how do people work on circuits that have computer processors in them or Wi-Fi or things like that better in the gigahertz range?
@jewishcrimenetwork They are different beasts. The Rigol is a more versatile instrument for general use, as it offers (poor compared to the 2246) analog performance, and single shot digital sampling the 2246 doesn't have.
Where is part 2 ?Thanks!
Tektronix is a low end cheap oscilloscope???
Lawrence Lederer You have to take Dave with a grain of salt. Good info, take the factual stuff, ignore his opinions. Much like any University professor.

@EEVblog Hi. thanks for the answer. The question is would you buy a new rigol DS1052E or a 2nd hnad Tektronix 2246? Thanks.
@jewishcrimenetwork An excellent basic readout analog scope.
Considering you can easily do the firmware upgrade to the Rigol DS1052 to upgrade it per the video instruction here, I'd bet it's much better to buy the Rigol.
I'm very happy for your video.

What kind of signal? What kind of conclusions do you need to make on it? If heterodyne probe adapter is an option, you can use a cheap scope too.
How about maximum input?
Are there more limitations in PC based Oscilloscopes?
Does any scope manufacured after 2015 "cheat" with equivalent sampling?
this is more a lecture than a tutorial, I thought it was about how to use a scope; but very good stuff nonetheless, thanks!
ive noticed that on DSO's they have a usb port on the front is this a way of increasing the memory depth ?? might be a stupid Q but ive only just begun looking at scopes and lecy stuff in gen watched many of ur vids on scopes and the have been very informative and well constructed thanx for all the posts ;)
No, definitely not.
USB data rate is too slow to use it for increasing the memory depth and taking realtime measurements.
Jeff is right, you are the BEST!!!! thanks Dave!!!
What is your opinion on the Tektronix 2246?
Thanks.
hey i was looking at upgrading from my old analog scope what would be a good one
i seen this would this even work?
What do you think about the ATTEN ADS1062?
@blade004 There is an ad on my eevblog dot com website for the Rigol from an Australian supplier, only $399. Tell'em I sent you.
So Far, So Good

Where is part 2? Its not in your oszilloskop Playlist
Ok, found it
@EEVblog Thanks. I will buy the rigol.
Sir what should I expect to spend on a oscilloscope, I just buy and sell stuff and would like to check stuff I buy, not on a big scale, just the odd thing, can you please give me an approximate price and model, like I said it can be very basic but would love to hear from the guru himself, thank you very much fr9m Canada.
'Won' an HP54201A digitizing scope for $83 to my door on ebay. Specs say-
'Dual 200 mega sample/ second allowing 50MHz single shot wave form capture.'
I am repairing electronic (musical) organs for recirculation into the community. With the advent of Craigslist the market is flooding with low dollar organs that were once high dollar. Most are analog transistor oscillator card ( personal favorite ala' Ray Manzarek), opamp based. Save for tone wheel Hammonds, tubes are rare.
Is this scope OK?

I was hoping this was going to be a tutorial, not an analysis of requirements that make a good scope. nonetheless, good stuff mate.
well i watched the first half and it missed some major questions i have, i shall try the second half video instead, but i think it missed a load of beginneres questions
how much would i have to pay for 100mhz oscilloscope digital 2 channel
I think its time to remake these..
How so? Which parts of it have changed?
PTNLemay Potato cams are much higher resolution these days. And angry Dave is funny Dave.
@JRogue250 if he was biased he wouldn't point out the flaws in these things. you really need to watch more of his videos to realize that a. he knows what he's talking about and b. if something is crap he will say it's crap and I really doubt that a paid biased advertiser would point out the fact you can buy the cheaper one and hack it to get the more expensive one for no extra cost.
@gotaimabara The oscilloscope equivalent to a cheap chinese meter is this:
2 Channel PC Computer Digital mini USB Oscilloscop
Operating systems used: W2K, XP ,Windows 7(32bit)
Signal input: BMC connection with universal oscillograph probe
Max sampling: 8kHz x 1/ (4kHz x 2)
Measurable frequency: 0Hz -----3kHz
DIV array: horizontal 16DIV x vertical 10DIV
Max voltage: 0---5V
Error of voltage measurement: ±30mV
Adjustable range of time domain: 10 mS/DIV----10800 S/DIV
Go search Ebay for it.
He looks much handsome now than he looked 9 years ago.
Nothing like that, anyone can set up a excellent lab on under $1000.
@gotaimabara Have you even seen my video that totally slag off these companies (and others) ?? You are massively wrong.
Wow, goid old EEVblog.
thnks
he really knows oscilloscope.
Hi Dave) from 2024🎉
Is this video still relevant?
they are called osmelloscopes -proud ave fan
THEY OUGHT TO SPECIFY THESE SCOPES WILL NOT WORK WITH WINDOWS 8, THE DRIVERS WONT INSTALL, HANTEK 6022BE - Fred in UK.
or instead of worring about sampling rate, just buy an analog scope.
Oh come on man. "Cheap scopes like Tektronix"? They cost 10 times more because they are 10x better. Rigol is a knock off they ripped from the contract work they do for Agilent.
