- Part1 Unpack, description,commands and a simple test DSO120M KKMOON portable oscilloscope.Very easy to use and versatile, 120Mhz band , 500Msps, 100Mhz 1X/10X probe and many more.
Follow for part2 - Dismantle and a look inside, components and more tests.
This is not a promotion or products placement, it's my own oscilloscope payed with my own money!
Need a multimeter? ..check this kaiweets.com/p...
My Friend just bought one of these, so he sent me the link to your video so I could see what he bought. That's a nice little digital CRO.
For the money yes, it's a nice tool! Very useful for hoobiest and experiments.
No Cathode Ray Tube in this one :-)
@@buddhistsympathizer1136 Correct, it's digital, so it's just a scope, not a CRO! The old terminology sticks around.
@@BrucePierson It's cool - I make similar mistakes sometimes as well, being of the older generation - All the best to you
In order to be of any real use a scope needs two channels. My best scope is a Hantech USB scope but limit band width. I have a DSO 138 and 150. Hell I have a second DSO 150 kit I never opened.
I still have DSO138, great little tool, cheap and working ok for audio needs , at least I'm not crying if is burning!
@@viocaia It took me a few hours to build that. just as many beers and other issues.
@@pulesjet same here!😂
Have you tested this by testing 120V or 220V AC line voltage to see how clean the sine wave it? (or an Inverter??)
It does seem that most (or all) videos on this model are consistent in that it does not handle 120 Mhz either at all or not in a stable manner.
I wonder, have you tried the higher Mhz tests using a much better probe?
I also have a Hantek MSO 5202D which I absolutely love! Obviously, I don't expect this cheapy to be anywhere near the accuracy of my Hantek, but I wonder if using the probe from the Hantek might get this handheld to work better at higher frequencies??
Ideas?
I don't have it anymore..I recall it is ok for low frequencies, excellent for audio !
Congratulations, very good explanation.
I just bought one of these and when I plug in the USB cable to recharge nothing appears on the screen, only the black screen appears.
Should it show some information while charging while off?
The other functions are apparently working.
Do you want to know if the missing loading information is a defect or if this is normal?
I appreciate if you can clear my doubts about the recharge of the internal battery.
It's just loading, there is no special software for it, a simple Li-ion controller taking care of the load.

Thanks!
Please subscribe! There will be more to go..
Mine begun to shutdown when i connect usb cable whet its powered on.I measured battery output socket, the voltage is not constant. I think the problem is about TP4056 chip or circuit.
Very possible, check the cell status too...
Can i mesure the voltage with high current
Or possible to damage the oscilloscope
You can measure until 400V AC with a 10x probe. For measuring current, you need a clamp adaptor.
@@viocaia thank you for your answer
What about the dc voltage
For example show the voltage a dc motor controled by a mosfet
30v and 4A
@@mohamedaitmouali895 Of course
800v PP is quite good. My Other DSO's are limited to under 35 - 50V I think ?
It's pretty ok, at least to 16Mhz, max I could tested lack of a proper signal generator.
Pls can I use it for car sensors diagnostics
I'm not sure...Probably yes..
Can i mesure the curent with this oscilloscope
Not quite, not directly. You need a shunt in series with the circuit and get the voltage from the shunt terminals, few millivolts. There are also kind of clamp adapters for oscilloscopes so you can measure current.
@@viocaia thank you
Can you note other oscilloscope like this (not expensive) mesure directly the curent
@@mohamedaitmouali895 I didn't hear of something like this...a dedicated current measuring oscilloscope. Sorry...
Thank you
Thanks .
Welcome
hello
please this real 120mhz /??
i can use this for tv LCD for image test and other for use for testing crystal and ics for laptop motherboard chip ic ?
is please confirme this for me or give me tha name for good cheap oscilloscope
No way! It's more like 20MHz max! Don't waste your money!
Good and cheap..tricky..but I found Hantek 5102p very nice..
The probe is poor quality but easily do 80 ot 100Mhz with decent probe.
@@arnolduk123 It's better then nothing..good for hobby
@@viocaia Yeah totally agree, it has all the bells and whistles of a high end oscilloscope, just lacking the precision. can't complain for less than $100. why anyone would compare this to a $500+ oscilloscope must be stupid.
