To monitor any of the demodulated 8VSB input signals, one of the 8VSB input ports can be
assigned to the output ASI monitor interface. The demodulated 8VSB input signal will then be
copied onto the monitor port for further analyzing or monitoring of the transport stream. Normal
operation will not be affected if the monitoring port is used.
The status parameters for the 8VSB module are shown in below. Click on the letter
representing in the input channel (A, B, C or D) to display the status parameters for the specific
