Features Descriptions M6100 Broadcast Satellite Modulator
• On: The transport stream packets are generated with a PID value that
is inserted in the first two bytes following the sync marker (byte 1 and
byte 2) of each data packet. It is used for proper error detection when
the rate of the generator is lower than the interface rate of the modulator
board or when the test generator is configured to create a burst of
transport packets (data packets combined with null packets).
PID Value Configure the PRBS generator PID value.
Number Data
Packets
Configure the number of data packets per burst that the test generator
has to generate. The baseband source can generate alternating bursts
of data packets and null packets. Once the burst is finished, it starts over
repetitively. This is controlled by setting the number of data packets and
null packets. This command controls the number of data packets per
burst. The continuity counter is not reset when the next burst starts. A
maximum of 255 data packets per burst is possible.
Number Null Packets Configuration of the number of null packets per burst that have to be
generated.
12.8.1 PRBS Monitor
These parameters can only be set on the following location:
M6100> ASI Input >> PRBS Monitor
Parameter Description
Enable Enable the PRBS Monitoring.
PID Handling Enable/disable the detection of a PID inside data packets of the PRBS
stream.
PID Value Configure the PRBS monitor PID value. Define which PID value must be
filtered out of the incoming data.
