Super cheap oscilloscope

[dragonbat13]

Ive wanted a PC based scope for awhile. I can't afford much more than this right now. But somewhere I read it was an OK scope

Owon VDS1022I USB PC Virtual Oscilloscope, MIT USB Isolation, 25 MHz Analog Bandwidth https://a.co/d/04zzpqAq

Anyone know anything about it?

Even if I get it, I intend on getting something better as funds allow and I learn a scope. But at least with this I could learn a thing or two.

After doing some reading and reviews, I went ahead and bought it.

Hope it works well for tube amp work. It comes with a 10x probe. I will eventually get some better probes if necessary since I'll be able to use them with a different scope.

Well I FINALLY got an opportunity to use this thing. It works good.

For what I paid it's decent. The only thing I don't like is the fact the two USB ports are required to use it.

The probes are OK. Probably about as good as it can get for a 100 dollar scope.

Hopefully my amp building will crank up soon.

My next purchase is a bench top drill press for board construction.

Check the manual for the channel input voltage limit.
Might be only 50V.

Check the manual for the channel input voltage limit.
Might be only 50V.

I checked, it is 400Vpp for both DC and AC.

Do you mean 400Vp or 400Vpp?
A peak-to-peak specification would be unusual.
400Vp = 2 * 400Vpp.

Matthias Wandel has something interesting on a cheap scope...

400Vp = 2 * 400Vpp.

From the manual, section tech specs:

With a sine signal 400Vpp equals 200Vp or 141Vrms.
Not sure what this mean for the DC limit.
