Analyzing a Differential Communication Signal
Youare having intermittent problems with a serial data communica-
tion link, and you suspect poor signal quality. Set up the oscilloscope
to show you a snapshot of the serial data stream so you can veri fy the
signal levels and transitiontimes.
Because this is a differential signal, youuse the math function of the
oscilloscope to viewa better representation of the waveform.
