    Good looking tool! Very detailed compared to the cheap one I’ve had for a while

    Breaks it… "… we’ll see how good those are…"

    Thanks for the good video! I was using the previous model but the resolution is not even close as this one and it makes it harder to be accurate! I just ordered this newer model and I can’t wait to start using it!

    im just getting into building guitar distortion pedals (TS808) tube screamers and Fuzz face . im wanting to get an Oscilloscope to be able to see how my circuit changes the sine wave at each component , would this work for my application ?

    What is the maximum Vpp that this unit can measure using the stock leads?

    Does anyone knows where you can buy it? amazon doesn’t works.

    You should try the 1013D tablet oscilloscope. You can get it very cheap from china. It looks really handy and alot more advanced than that Liumy.

    When you test the Head Unit for clipping, where do you put the leads? At the RCA outputs or speakers. Everything in my system i just installed is connected through RCA to the amp.

    Awesome vid man. Thank u.

    When I measure my max radio volume before clipping, it goes north off of the screen. How can I get it back on screen?

    i need your help please 🙏🏼 does a cheap oscilloscope (5mhz bandwidth) shows me a full sine wave above 50v on the output of amplifier? The reason im asking is because mine one always squares it on anything above 32v output (amp). I have tried changing the amplitude on the oscilloscope by pressing the voltage button from 10v to 20v 50v 100v 200v and the arrows to put the sine wave right at the bottom so i get to see the top of it but still, so im not sure if im getting a square top or the wave is actually going pass what my cheap oscilloscope can show :/ Amp is 3000 rms which can go up to 78v all i need is 57v output but im not sure if is a dirty signal or not. Amp isn’t clipping (light on it) until i go pass 80v output. Please give me your opinion on this one 🙏🏼
