Title: 2 Channel PC Computer Digital mini USB Oscilloscope $33.80 AUD

Guys,
Saw this on Ebay

Looks like a nice cheap solution for guys wanting to see what is going wrong with their electronics without having to fork out for a real  CRO or Digital Oscilloscope. I haven't got one, i've got an old CRO but I'd give this a go if I didn't.

Measurable frequency: 0Hz -----3kHz

There is your problem (and the same thing is the problem with most of these PC based add-ons).

An upper limit of 3Khz is FAR too low to be of much use.

In fact a logic probe would be more useful!

DOH should have checked the info more carefully. Thanks for correcting me. I didn't even consider speed, my CRO is probably 30 years old, I assumed the PC would have creamed it. Oh well :tumble:
