Setting format: [:SOURce]:DM:IQADjustment:QSKew <val>
Query format: [:SOURce]:DM:IQADjustment:QSKew?
Parameter:
<Offset> I/Q adjustment orthority offset.
Range: 0deg [-10.00deg
，
+10.00deg].
Example: :DM:IQADjustment:QSKew 30deg
Set the Orthority Offset for I/Q adjustment to 30deg.

[:SOURce]:DM:IQADjustment[:STATe] <State>
Function: This command enables I/Q Adjust ON/OFF. After this function is turned on, the
parameters adjusted: Gain Balance, I Offset, Q Offset and Orthority Offset are
superimposed on adjustment circuit; after this function is turned off, the above
parameter values are not used, but the modulation attenuation is not affected by the
ON/OFF state of I/Q Adjust. For related commands, see

Setting format: [:SOURce]:DM:IQADjustment[:STATe] ON|OFF|1|0
Query format: [:SOURce]:DM:IQADjustment[:STATe] ?
Parameter:
<State> Boolean data is as follows:
ON | 1: I/Q Adjust is turned on,
OFF | 0: I/Q Adjust is turned off.
Example: :DM:IQADjustment 1 Turn on I/Q Adjust.

[:SOURce]:DM:MODulation:ATTenuation <Atten>
Function: This command sets the attenuation of I/Q signal modulated by the signal generator RF
channel. The output of the output attenuation can be set when Attenuation is in
Manual state. Attenuation is valid even if I/Q Adjust is turned off. For related
commands, see ―
