Looking for a Serial Data Tester

TurnipTruck

Greetings,

Does anyone know of a hardware product for testing serial data link qualities? I'm envisioning some sort of tester that can be put onto 232, 422 and 485 lines to read signal to noise ratio, common mode balance, etc.

Thanks.

A scope with a differential probe is your best bet.

You can then see ringing, noise, common mode voltage issues, etc.
