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.
