Bias

If a bias is enabled, a DC voltage is superimposed upon the envelope signal E and the
inverted envelope signal E BAR.

Use this parameter to define the operating point of a DUT.
Remote command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:ENVelope:BIAS

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.
