The valid operating range for each item in this section is noted in parentheses.
• Tx RF Frequency (0 to 67150 MHz) – This is the frequency at which the terminal transmits to
the satellite. Once you configure this to a non-zero value and
enter a BUC LO Mix and BUC
LO Frequency, the modem automatically configures the L-Band or IF frequency.
Enter the Tx RF Frequency in MHz. Click [Submit]. Once you submit the Tx Rx Frequency and
you enter a BUC LO Frequency, the modem displays the resulting Tx RF Frequency.
If you leave the BUC LO Frequency at the default setting of zero, then the modem does not
calculate the Tx RF Frequency.
The BUC LO Mix and BUC LO Frequency entries are provided for calculation
purposes only. BUC configuration is not
updated as a result of configuring these
parameters.
• BUC LO Mix – Use this drop-down list to select the BUC LO (Low Oscillator) Mix as Upconv
(SUM): RF=LO+LBand or DownConv (Diff): RF=LO-LBand.
Consult your BUC adjunct product datasheet or its Installation and Operation
Manual for the type of BUC (Upconverter [Sum] or Downconverter [Diff]) being
used.
• BUC LO Frequency – Enter the known BUC Tx LO (Low Oscillator) Frequency in MHz.
Consult your BUC adjunct product datasheet or its Installation and Operation
Manual for the LO Frequency.
• Tx L-Band Frequency (950 to 2150 MHz for L-Band, 50 to 180 MHz for IF) – Enter the L-Band
or IF-Band frequency in MHz. Click [Submit].
