"Use a scope and look at the eye-pattern. This will show the presence of noise and reflections on the signal as well as gross jitter. This will also show the signal levels."
Tony, I can see how to put the SPDIF bit stream on one scope axis, but how do you connect data rate to the other one? Can you refer me to a "how to" paper or similar source on the web? BTW, I have a pretty basic 30 Meg two channel single beam analog scope, and I would like to play around with the eye-pattern measurement. I looked at the HP article that you referenced, and their method seems to involve a lot of ancillary instrumentation. Thanks in advance.
