Symbol Rate
The Symbol Rate parameter sets the modulation symbol rate value in Spc.
NOTE:
In DSNG modules, the actual output rate of the encoder can be set according to either the Symbol Rate
(from the Modulation menu) or the Output Rate (from the Transport Stream menu). The actual rate will be the
rate last configured.
For example, if the symbol rate value was set after the output rate value, the symbol rate value is the actual
output rate of the encoder.
This means that in DSNG modules (with an IP or L-Band modulators) the actual output can be one of two
settings, either it is set according to Symbol Rate (using the Modulation menu) or according to Output Rate
(using the Transport Stream menu).
The range is 50,000 to 68,000,000 sps. The Symbol Rate default value is
10,000,000 sps
.
NOTE:
The user cannot exceed the symbol rate (or the equivalent output rate) for more than allowed
according to the encoder license.
