[:SENSe]:FEED?

Selects the input signal. The default input signal is taken from the front panel RF input port. For calibration and testing purposes the input signal can be taken from an internal 321.4 MHz IF alignment signal or an internal 50 MHz amplitude reference source.

If the baseband IQ option (Option B7C) is installed, I and Q input ports are added to the front panel. The I and Q ports accept the in-phase and quadrature components of the IQ signal, respectively. The input signal can be taken from either or both ports.

RF selects the signal from the front panel RF INPUT port.

IQ selects the combined signals from the front panel optional I and Q input ports.

IONLy selects the signal from the front panel optional I input port.

QONLy selects the signal from the front panel optional Q input port.

IFALign selects the internal, 321.4 MHz, IF alignment signal.

AREFerence selects the internal 50 MHz amplitude reference signal.
