hey
i'm looking for digital programmable oscilloscope, which is provided
with API.
I need read some data from the oscilloscope and save them in file, so

Readout pin on oscilloscope probes
Philipp Klaus Krause - 2009-06-07 09:40:00
Where can I find information about the readout pin present on some
oscilloscope probes? Googling just turns up lots of pages of people
selling such probes, but no protocol documentation, etc.

I just converted a 5" B&W TV into a very basic oscilloscope. I now

would like to improve is the keep the electron beam at a constant

If it's a regular brushed motor it will generate a lot of spikes. Best
