[:SOURce]:DM:MODulation:ATTenuation:AUTO <State>
Function: This command sets the Manual state of the signal generator I/Q channel attenuator.
When Manual mode is enabled, current attenuation remains unchanged. For
modulator attenuation, see the command ―
:DM:MODulation:ATTenuation
‖; after
Manual mode is disabled, the user can not change attenuation, and the signal
generator will select the optimum attenuation value for its current status automatically.
Setting format: [:SOURce]:DM:MODulation:ATTenuation:AUTO ON|OFF|1|0
Query format: [:SOURce]:DM:MODulation:ATTenuation:AUTO?
Parameter:
<State> Boolean data is as follows:
ON | 1: Modulation Attenuation is in Manual state,
OFF | 0: Modulation Attenuation is in Auto state.
Example: :DM:MODulation:ATTenuation:AUTO 1
Modulation Attenuation is in Manual mode.
Reset status: 0

Query format: [:SOURce]:DM:STATe?
Parameter:
<State> Boolean data is as follows:
ON | 1: I/Q Modulate is turned on,

[:SOURce]:DM:SOURce <Mode>
Function: This command selects I/Q Data Source entering IQ modulator of the signal generator.
There are two modes for selection, EXTernal and INTernal.
Setting format: [:SOURce]:DM:SOURce EXTernal| INTernal
Query format: [:SOURce]:DM:SOURce?
Parameter:
<Mode> Discrete data. I/Q filter is selected as follows in Manual mode:
EXTernal | 0:
I/Q signal input matching EXT50Ω,
INTernal | 1: Internal I/Q signal input to I/Q modulator,
Example: [:SOURce]:DM:SOURce EXT Set I/Q Data Source as EXT.
Reset status: EXT
