soundcard Oscilloscope ?
(1/1)
niall:
looking at Burnit,s thread and drooling over his Oscilloscope , i,m wondering if some of the freeware software scopes are usable for a similar function of looking at mosfet,s fiddely bits ....
heres one of such ....http://www.zeitnitz.de/Christian/scope_en
seems the sound card limits the max v input (.7v) or else it might go pop....but if as in the link above suggested a V divider is used ..it might give a similar performance level ?
say if a fet gate was being pwm,d at 18v.....and a divider of 20k to 1k used to sample the signal..
does anyone have any experiance of using a software scope ?
madlabs:
I messed with a souncard 'scope a few years back and wasn't too impressed. It was a while ago though and I only tried the one. There are some pretty cheap digital 'scopes out there now, if you can scrounge the cash I'd go for one of those.
