CDM-625 Advanced Satellite Modem
Front Panel Operation
5.10.1.2 ODU: BUC:PwrSupply+Ref
BUC-LO Frequency= 00000 MHz
This menu permits the user to enter the BUC LO frequency for the up conversion. Entering a non-
zero value for BUC LO will cause the Tx-IF frequency menu to show LO and Satellite frequencies.
The Mix sets the polarity for the upconversion mix in the BUC:
•
•
Satellite frequency = LO frequency +/- modem frequency.
Select the parameter to edit using the
MHz; the available options are shown in parentheses. Use the
then press ENTER when done.
5.10.1.3 ODU: BUC:PwrSupply+Ref
BUC Power Supply:
This display shows the power supply current and voltage information. Press ENTER or CLEAR

5.10.2 ODU: LNB:PwrSupply+Ref (Power Supply and Reference)

LNB control/monitor:
PSU-and-10MHz
The modem can supply DC power to an LNB connected to the Rx N-type connector. It can also
supply a 10MHz reference for a phase-locked LNB.
