I'm looking for a PC-based 'scope to measure the ripple voltage of various ATX power supplies and have pretty limited experience with oscilloscopes in general so I'm really not sure what I need. I definitely want the 'scope to be PC-based, though.
So far, I've had the ADC-200 and ADC-212/3 recommended for my needs and, of course, I'm looking to find out which would be better suited to my needs. For now, all I need to do is measure voltage ripple as part of a larger suite of tests to determine power supply quality.
If one 'scope or another can do that and potentially also measure things like video signal strength for a PC graphics card, that would be a bonus, but not necessary. Really, I'm just looking for the cheapest PC-based option to reliably measure ripple.
Any thoughts or suggestions? Thanks.
