SLM-5650A Satellite Modem
Front Panel Operation
When entering the data rate, the following interactions need to be taken into
account:
If the modulation type selected is 8PSK, 8QAM, or 16QAM the minimum data rate
allowed is 256 kbps.
When changing certain parameters like modem type, the data rate will default to 64
kbps or 256 kbps.
The calculated symbol rate is displayed for the user. This is helpful for determining
the occupied bandwidth required for the selected modulation type, code rate and
overhead.
