L-Band Modulator Parameters
11.2 L-Band Modulator Parameters
This group of parameters sets the L-Band modulator configuration.
Some of these parameters are unique L-Band modulator parameters and are detailed in the
following sub-paragraphs:
■
Carrier parameter, see 11.2.1 Carrier .
■
L-Band Power parameter, see 11.2.2 L-Band Power .
■
Reduced L-Band Power, see 11.2.3 Reduced L-Band Power .
■
TX RF Frequency parameter, see 11.2.4 TX RF Frequency .
■
RF Conv. LO Frequency parameter, see 11.2.5 RF Conv. LO Frequency .
■
L-Band Frequency parameter, see 11.2.6 L-Band Frequency .
■
Remote Power 24 VDC parameter, see 11.2.7 Remote Power 24 VDC .
■
10 MHz Clock parameter, see 11.2.8 10 MHz Clock .
NOTE:
This set of parameters is not available for IF modulator units. All other parameters are common to both
modulation schemes and are detailed in 11.4 Common Modulation Parameters on page 315.
The common modulation parameters are detailed in the following sub-paragraphs:
■
Modulation On/Off parameter, see 11.4.1 Modulation On/Off .
■
Symbol Rate parameter, see 11.4.2 Symbol Rate .
■
Spectrum Inversion parameter, see 11.4.3 Spectrum Inversion .
■
Modulation Scheme parameter, see 11.4.4 Modulation Scheme .
■
FEC and Modulation parameter, see 11.4.5 FEC and Modulation .
■
Frame Length parameter, see 11.4.6 Frame Length .
■
Operating Mode parameter, see 11.4.7 Operating Mode .
■
Roll-Off Factor parameter, see 11.4.8 Roll-Off Factor .
■
Pilot Mode parameter, see 11.4.9 Pilot Mode .
