Bias
If a bias is enabled, a DC voltage is superimposed upon the envelope signal E and the
inverted envelope signal E BAR.
"I/Q Output Type" Termination "Bias" defines
Single Ended - The bias between the envelope signal E and ground
Differential "To Ground" Superimposed DC voltage = "Bias", where "Bias" is
related to the selected
R
in
.
See also Table 7-8
"Wire To Wire" Superimposed DC voltage = "Bias", where "Bias" is
related to high impedance (1 M
Ω
).

Offset
Sets an offset between the envelope and the inverted envelope signal.
The value range is dynamically adjusted.
The selected offset is set half in the positive and half in the negative direction.
