Thx for all your help. Without your help, I would have been stuck with a pretty bad interface. It meets a very basic needs for troubleshooting AC circuit, but I can already see a need for 2 channel and higher freq for real troubleshooting and doing more then quick checks. I'm looking at the Owon sds6062.

thank you for your quick reply!!

I've tried the Vellemen on the ignition module output on my car, which is what I wanted a pocket scope for. Gives me a nice clear trace on that.

's funny the fit function didn't do a good job at all on 201. I still like it for what it is though. I hope they bring out an improved version in the future.

Have you tried the Velleman and Nano on testing sensors on a car?? Such as oxygen, air/fuel or camshaft sensors. I'm thinking of buying the Velleman for those uses. What do you think?? Thanks

Which one is better for testing when a head unit in a car starts to clip and at what volume?

Can the DSO201 Oscilloscope save screenshots via usb port, or some other conection?

It could have been so good - but for the focus and any lack of comment....

Hi. The firmware upgrade gets rid of the purple wave. I bought my DSO from "Nichegeek" on Ebay and they emailed me the firmware upgrade. Message me your email address and I'll email it to you.

the ds203 is quite a bit better than than the ds201.

ok das hps140i ist besser. Es kann auf jeden Fall eine Frequenz von 1MHz sauber darstellen. Das dso201 schafft nur 0,1MHz sauber darzustellen.

???????????????????????

That was awful
