Appendix F MN-CDM625
F–11
F.3.3.3.1.2 ODU: BUC:PwrSupply+Ref LO Freq (Local Oscillator
Frequency)
BUC-LO Frequency= 00000 MHz
Mix= High [-] (Hi,Lo) ()
Use the
◄ ►arrow keys to select BUC-LO (Local Oscillator) Frequency for the upconversion, or
Mix to set the polarity for the upconversion mix in the BUC.
On the top line – To set the BUC-LO Frequency, use the
◄ ►arrow keys to select a digit to edit,
and then use the
▲▼ arrow keys to change that digit. The valid LO range is 3000 to 65000 MHz.
Entering a non-zero value for BUC LO causes the Tx-IF frequency menu to show LO and Satellite
frequencies (
satellite frequency = LO frequency ± modem frequency).
Press ENTER when done.
On the bottom line – To set the Mix polarity, use the
▲▼ arrow keys to set polarity as Hi (to
indicate a high side, inverting mix) or Lo (to indicate a low side, non-inverting mix).
Press ENTER when done.
