Installing the Waveform Monitor in a Serial Video System
The serial digital monitor can operate almost anywhere in the distribution system
due to its high impedance, bridging, loop-through inputs. This section describes
two types of connections and presents useful information on line termination.

Most serial equipment employs a receiver that regenerates an output signal, such
as the receiver shown in Figure 1–6. Routing the incoming serial signal through
one of the waveform monitor loop-though inputs and connecting the output of
the serial receiver to the other loop-through input allows you to compare the
incoming signal and the regenerated output signal.
