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.
