[:SOURce]:RADio:TTONe:ARB:IQ:MODulation:ATTen?
This command sets the attenuation level of the I/Q signals being modulated through the signal
generator RF path. The variable <val> is expressed in decibels (dB).
Example
:RAD:TTON:ARB:IQ:MOD:ATT 20
The preceding example sets the modulator attenuator to 20 dB.

[:SOURce]:RADio:TTONe:ARB:IQ:MODulation:ATTen:AUTO ON|OFF|1|0
[:SOURce]:RADio:TTONe:ARB:IQ:MODulation:ATTen:AUTO?
This command enables or disables the modulator attenuator auto mode. The auto mode will be
switched to manual if the signal generator receives an AUTO OFF or AUTO ON command.
ON (1) This choice enables the attenuation auto mode which allows the signal generator
to select the attenuation level that optimizes performance based on the current
conditions.
OFF (0) This choice holds the attenuator at its current setting or at a selected value. For
setting the attenuation value, refer to “:IQ:MODulation:ATTen” on page 312.
Example
:RAD:TTON:ARB:IQ:MOD:ATT:AUTO ON
The preceding example enables the attenuator automatic mode.
