5.4.4.7.3 Satellite Modulator Modulation Configuration
The following parameters are available through the Advanced Setup tab of the
Device Configuration page under Slots > Slot <n> - Satellite Modulator Option
Card > Satellite Modulator > Modulation Parameters or on the Modulation
Parameters tab in the Properties widget of the Service Configuration page if one
of the Satellite Modulator Output Stream is selected in the Outputs widget. The
same parameters can be accessed through the Advanced/Satellite
Modulator/Modulation Parameters menu on the front panel.

Description
user-defined symbol rate setting.
When rate adaptation is disabled, the modulator card tries to
lock its symbol rate to the input data rate, but it can only do so
if the configured input data rate is within the tracking range of
the input rate control PLL (approximately ±122 ppm). If this
does not match, errors will be seen at the output.
The size of the input buffer.
The source of the 10 MHz reference clock used by the satellite
modulator. External mode is not supported by the current
hardware configuration.
Specifies whether to use RAS scrambling.
The 7-byte key used for RAS scrambling.
The version of the RAS implemented on the satellite
modulator.
Description
Specifies the modulation standard to use for satellite
transmission.
Turns on or off the modulation of the carrier. If the output is
enabled and modulation is turned off, an unmodulated
carrier is output.
Specifies whether to transmit ISSY and if so, whether to use
a two or three-byte ISSY field in the BB header.
Same as above for the 2nd Transport Stream in VCM mode.
If set to On, null packets will be deleted from the incoming
Transport Stream.
