A friend who is handy with computers but not so handy with oscilloscopes wants me to help him interpret what he is seeing on his Tek scope. But I live about 1,000 miles away. It seems like a PC-based scope might be handy if he could e-mail data files to me in some format that I can use to "look over his shoulder" on my PC to see what he's been seeing.
Either screen captures, or several seconds of data playback. I operate in teacher mode with him. Maybe the scope software has a "scope viewer" module for not much money.
I could use recommendations for something under $500
USB
2 channels external sync input along with the usual internal line, edge, etc., sync modes. 8 bits is enough bandwidth: single-shot mode, to 100kHz; in repetitive mode to 1MHz. Reliable, voltage-protected inputs good solid software, portability not really needed.
