Description of Arguments
(Note that all arguments are ASCII numeric codes from 48 and 57)
Command or Query.
Sets or returns Rx Terminal Frequency, in MHz, being received from the
satellite in the form xxxxx.xxxx, where:
xxxxx.xxxx=value from 950.0000 to 65000.0000 MHz (L-Band), in 100 Hz
increments.
NOTES:
1) If RX LO=00000, then the Rx Frequency is entered as L-Band direct –
950.0000 to 2150.0000;
2) If RX LO is set in the range of 30000 to 65000, the Rx Frequency is ±Rx
LO, and this will be the resulting L-Band frequency the modem will expect
to receive.
