WBFM?
Prepares message containing information on Wideband
Frequency Modulation setting in the following format:
:WBFM:DEVN <nr2>;<coupling>;<status>
where <coupling> is a program mnemonic indicating AC o
DC coupling of the modulation signal and <status> is
a program mnemonic indicating whether the
modulation is locally ON or OFF
Example:
:WBFM:DEVN 500000.0;AC;ON
