Effect of a positive bias Effect of a negative bias
In "Single Ended" mode, this parameter defines the bias between the output signal and
ground. It can be used to define the operating point of a DUT.
The value range is adjusted so that the maximum overall output voltage does not
exceed 4V, see "Maximum overall output voltage" on page 186.
Remote command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:BIAS:I on page 1055
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:BIAS:Q on page 1055
Offset (EMF)
Sets an offset between the inverting and the non-inverting output.
The value range is adjusted so that the maximum overall output voltage does not
exceed 4V, see "Maximum overall output voltage" on page 186.
The selected offset is set half in the positive and half in the negative direction.
Effect of a positive offset Effect of a negative 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.
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.
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
