Analyzing a Differential Communication Signal
You are 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 verify the
signal levels and transition times.
Because this is a differential signal, you use the math function of the
oscilloscope to view a better representation of the waveform.
