command: [:SOURce[n]][:CHANnel[m]]:FM:STATe[l]
syntax: [:SOURce[n]][:CHANnel[m]]:FM:STATe[l]<wsp>OFF|ON|0|1
description: Enables and disables frequency modulation of the laser output.
parameters: A boolean value: OFF or 0: disable frequency modulation
ON or 1: enable frequency modulation.
response: none
example: sour2:fm:state 1
affects: Keysight 81960A, 81980A, 81940A, 81989A, 81949A compact tunable lasers.
command: [:SOURce[n]][:CHANnel[m]]:FM:STATe[l]?
syntax: [:SOURce[n]][:CHANnel[m]]:FM:STATe[l]?
description: Queries the current state of frequency modulation of the laser output.
parameters: none
response: A boolean value: 0: frequency modulation is disabled
1: frequency modulation is enabled.
example: sour2:fm:state? -> +1<END>
