REMOTE INTERFACE

Sets or disables AM modulation. By default AM
modulation is disabled. AM modulation must be
enabled before setting other parameters.
Burst or sweep mode will be disabled if AM
modulation is enabled. As only one modulation is
allowed at any one time, other modulation modes
will be disabled when AM modulation is enabled.
SOURce[1|2|3RF]:AM:STATe {OFF|ON}
SOURce[1|2|3RF]:AM:STATe?
AM modulation mode is currently enabled.
SOURce[1|2|3RF]:AM:SOURce
Sets or queries the modulation source as internal
or external. Internal is the default modulation
source.
If an external modulation source is selected,
modulation depth is limited to ± 5V from the MOD
INPUT terminal on the rear panel. For example, if
modulation depth is set to 100%, then the
maximum amplitude is +5V, and the minimum
amplitude is -5V.
The RF channel supports only the internal
modulation mode.
