    Going to be ordering a pico this week... Thanks for informing me about these

    Just remember you don't need a high bandwidth scope for audio. You can get by with the cheaper options. Anything over 100MHz is overkill.

    It definitely has a pixelated LCD display, but the scale is easy to set. Not too tough to work around that, for gain setting and signal analysis using sine waves.

    What has a pixelated display?

    My little handheld single-channel Velleman.
    I still love it because back then, I'd have never justified spending $1500 on a real Oscilloscope. $250 was like a "holy shit!" opportunity to jump on before they figured out they should charge more. Still can't believe it's even cheaper today.

    Is that pico a dual channel? I wouldn't mind a dual-channel option, but honesty my Velleman has been good for what I do- I'm (sadly) not internally scoping amp guts.

    I actually was starting to look for one that also did all the DMM stuff too, but definitely want one with a continuity buzzer... my current DMM is just "OK", I'd pick up an upgrade if there was this rad added feature... like an O-Scope.

    I stand behind Pico Scopes because they work well for me and my team in an industrial environment. Your handheld is convenient but you are killing yourself on the display. A 2 channel Pico Scope for $115 blows it out of the water. Why pay for a display when your laptop already has a pretty good one? You can buy Pico Scopes from anywhere from $100 to $1000. It all depends on your needs. If you are just measuring audio signals then the 10MHz cheapo 2 channel model is perfect for you.

    I need to measure power supply and amp output switching frequencies. i spec a device that has 100x bandwidth and maybe 4 channels. Anyone here that does not need to operate on amps does not need this. So save yourself some money and enjoy the love.

    At work I have one or two scopes that can sample a 5GHz over 4 channels and decode comm buss signals like Flex-RaY, MOST, CAN, and LIN. These cost $20k each. A hobbyist does not need to spend this type of money anymore.

    Just wanted to say thank you for the suggestion, I ordered a pico and decided to also get a SMD DD-1+... Even thought the PICO will easily show me a clipped signal (along with other cool functions) i would still like to know when distortion (at least up to 1%) is present at which device is throwing it.

    Good choice. I know some folks like to judge clipping by watching a sine wave distort on a scope. But, by the time you see distortion you are well into the 10% and above range.

    Ok, so trying to understand here & forgetting their cost for the moment, with the SMD DD1 or DD1+, do you really even need the scope based on your comment about distortion already being high by the time you see the clipped signals?

    Besides setting gains, any other real or common benefit to using a scope in car audio?
    Finally get to update this, procurement & install planning phase has had some execution happen, procurement is for minor items now. Have Morel MT350 Tweeters & Hybrid MW6 Woofers, AudioControl DM-6.1200 & just added LC.1-800, KnuKoncepts Wiring and distribution, Audiofrog GS12D2 refurb, starting with inexpensive subwoofer enclosure to get everything up and running and let funds replenish some...Funds have replenished and now I am questioning my early DSP/Amp approach decision...

    Check voltage levels. Look for noise. See if your amp is clipping. Look at pretty sign waves. Etc...
