Does anyone here have any experience with using xoscope?
http://xoscope.sourceforge.net/ ... searching the forum didn't come up with any hits.
I'm trying to debug my old Thinkpad that's failing to power on. I suspect the voltage sensing circuit on the MAX1631 (see
http://kuzyatech.com/fixing-an-ibm-thinkpad-x31) but per the datasheet, that would cause the power to clamp off after 20ms, too fast for my (old, cheap, digital) multimeter to register anything. So I just need something to look if those circuits are twitching. Lacking the proper test equipment, I have already tried replacing the capacitors mentioned in that post but to no avail. So I'm hoping to do some probing.
I was considering a Siglent SDS1052DL at the current sale price on TEquipment, but given I haven't needed an oscilloscope in the past 15 years (since college), I'm finding it hard to justify the price - especially considering the Thinkpad is worth less than that
I'm thinking xoscope might do what I need; I use Debian Linux and it's available.
What I really don't know what kind of AC coupling sound cards have -- presumably they have a high-pass filter of some sort -- would they even give me anything recognizable on what would presumably be a 20-30ms pulse.
Has anyone used this (or similar) and have any experiences to share? Or should I just get the real oscilloscope and hope I find some more uses for it in the future.
Thanks!
