Hi there, I got the free software off the web for a Oscilloscope that uses the = soundcard for the sampling. My Question : Can anyone suggest a homemade Probe to use with this and = still have reasonable accuracy with this. Is there any way to break the 44.1KHz barrier and measure on higher bandwidths?
