I/Q Gain

Lets you adjust the ratio of I to Q while preserving the composite, vector magnitude.

Adding Gain (+x dB) to the signal increases the I component and decreases the Q

component proportionally. Reducing Gain (-x dB) decreases the I component and

increases the Q component proportionally.

Remote Command

:SOURce:RADio:ARB:IQADjustment:GAIN <value><unit>

:SOURce:RADio:ARB:IQADjustment:GAIN?

Example

:SOUR:RAD:ARB:IQAD:GAIN 0.5

:SOUR:RAD:ARB:IQAD:GAIN?

Notes Effective only if the I/Q adjustment function is ON

Dependencies Unavailable and grayed-out when the ARB state is OFF

Not available in E7760B

Preset +0.00000000E+000

Min -1 dB

Max 1 dB

I/Q Delay

Lets you change the absolute phase of both I and Q with respect to triggers and

markers. A positive value delays I and Q. This value affects both the external I/Q out

signals and the baseband signal modulated on the RF output. This adjustment does

not affect external I/Q inputs.

Remote Command

:SOURce:RADio:ARB:IQADjustment:DELay <value><unit>

:SOURce:RADio:ARB:IQADjustment:DELay?

Example

:SOUR:RAD:ARB:IQAD:DEL 10ps

:SOUR:RAD:ARB:IQAD:DEL?

Notes User-set IQ delay time values are rounded to the nearest integer multiple of the resolution

Dependencies Unavailable and grayed-out when the ARB state is off
