Figure 11: Four SDI signal connection for instruments with Option 2SDI
Connect a composite signal to one of the CMPST inputs on the rear panel of the
instrument. You must terminate the loop-through for this input. After that is
finished, use the front panel buttons to set the parameters for monitoring that
signal.
The composite inputs are passive and require external termination.
If this instrument is installed to monitor an operating link, the destination receiver
and the connecting cable serve as the termination. This monitoring connection
checks the performance of the entire path. The return loss of the instrument is
sufficiently high that, in most cases, the destination receiver sets the system return
loss.
