I/Q Level Vp EMF

Sets the output voltage for both signal components.

Couple I/Q Bias

In "Variable Mode", activates/deactivates coupling of bias setting of the I signal and the
Q signal component. With activated coupling, the settings of the I signal component
automatically apply to the Q signal component.
Remote command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:BIAS:COUPling[:STATe]

Bias (EMF)

If a bias is enabled, a DC voltage is superimposed upon the I or Q signal.

If "RF Envelope > On"
The envelope signal E is output at the I connectors.
●
If "RF Envelope > Off"
Single-ended output at the I/Q connectors.
You can define a bias between the output signal and ground.
The I/Q signal components settings are fixed to the value listed in
Table 7-3.
