R&S SGT100A
Effect of a positive bias
In "Single Ended" mode, this parameter defines the bias between the output signal and
ground.
Use this parameter to define the operating point of a DUT.
Remote command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:BIAS:I
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:BIAS:Q

Offset (EMF)

Sets an offset between the inverting and the non-inverting output.
The selected offset is set half in the positive and half in the negative direction.
Effect of a positive offset
A positive offset is set with half of the value in posi-
tive direction at the non-inverting outputs, in nega-
tive direction at the inverting outputs.
Example: Effect of a positive offset on the I signal component
"I Offset" = 100.0 mV
The offsets applied on the two output connectors as follows:
●
+50.0 mV at the positive signal output
●
-50.0 mV at the inverted signal output
Remote command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:OFFSet:I
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:OFFSet:Q

Effect of a negative offset
A negative offset is set with half of the value in neg-
ative direction at the non-inverting outputs, in posi-
tive direction at the inverting outputs.
