6.3 External Gain

Example Set the Ext Gain value to -10dB, and subsequently querying :LOSS will give 10 dB:

:CORR:BTS:LOSS 10

Set the Ext Gain value to 10dB. Subsequently querying :LOSS will return -10 dB:

:CORR:BTS:LOSS -10

Notes A positive value of <rel_ampl> in the above command means a loss and a negative value indicates a

gain

If :LOSS is set, :GAIN is set to the negative value of the parameter sent

If :LOSS is queried, it returns the negative of :GAIN

Affects the I channel input. However, when Q Gain in I+jQ is set to Same as I Gain,

this value is applied to both I and Q channel inputs.

Remote Command

[:SENSe]:CORRection:IQ:I:GAIN <rel_ampl>

[:SENSe]:CORRection:IQ:I:GAIN?

Example Set the I Ext Gain to 10 dB:

:CORR:IQ:I:GAIN 10

Set the I Ext Gain to -10 dB (that is, a loss of 10 dB):

:CORR:IQ:I:GAIN -10

Dependencies Not available unless option BBA is installed

Annotation Ext Gain: <I Ext Gain> dB

No annotation is shown when Input is not I/Q. Also not shown when I Ext Gain is 0.00 dB. I Ext Gain is

not shown for Input Path Q Only. When the Input Path is Independent I and Q and I Ext Gain is not the

same as Q Ext Gain, both are shown. "Ext Gain: <I Ext Gain> dB, <Q Ext Gain> dB"
