CALL:FM
CALL:FM:EXTernal:STATe
CALL:FM:INTernal[:SDEViation]
Function Sets/queries the external FM input (on or off). The FM deviation is fixed at 20 kHz/volt with a 1
volt maximum input voltage. You must make sure that the sum of the three FM sources (internal
FM, external FM, and SAT) do not exceed 20 kHz deviation. The performance of the signal is not
specified beyond 20 kHz deviation.
While in active cell mode, the internal and external FM states parameters will be overridden and
FM turned off temporarily by the call processing state machine during wideband signaling with
the mobile station. Querying during this temporary state will return user defined values. This
command applies in active cell mode while on an AVC, and in AVC test mode.
Setting Range: 1|ON|0|OFF
Query Range: 1|0
*RST Setting 0 (off)
Programming Example
OUTPUT 714;”CALL:FM:EXTERNAL:STATE ON” !Turns on the external FM input.
Function Sets/queries the internal FM source’s deviation and automatically sets the internal FM state to
ON. This is “complex” command.
Setting Range: 0 to 20 kHz
Resolution: 0.1 Hz
Query Range: 0 to 20 kHz
Resolution: 0.1 Hz
*RST Setting Internal FM: OFF
Internal FM: OFF
Programming Example
OUTPUT 714;”CALL:FM:INTERNAL:SDEVIATION 10 kHz” !Sets internal FM deviation to 10 kHz and
!automatically turns on the internal FM
!source.
