State
Activates/deactivates I/Q impairment.
If activated, the settings for leakage, I/Q imbalance and quadrature offset become
effective.
The state is indicated in the function block.
Remote command:
[:SOURce<hw>]:BB:IMPairment:STATe
I/Q Offset
Sets the carrier offset (in percent) of the amplitudes (scaled to the peak envelope
power (PEP) for the I and/or Q signal component. An ideal I/Q modulator suppresses
the carrier offset completely (offset = 0 percent).
