2) Connect a differential or single-ended input signal
(differential voltage amplitude between 700mV and
1100mV) to a cable. Connect the other end of the
cable to the cable equalizer inputs at SMA edge
connectors J8 (EIN-) and J7 (EIN+).
3) Connect a 50Ω oscilloscope to SMA edge connectors J3 and J4 to observe the output of the cable
equalizer.
4) The cable integrity monitor (CIM) outputs can be
monitored at TP1 (CIM-) and TP2 (CIM+).
5) The loss of signal (LOS) output can be monitored at
TP3.
