6.2.1 RF Input
Access (RF input settings): "Overview" > "Input" > "Input Source" > "Radio Frequency"
> "Config"
Access (schematic test setups): "Overview" > "Input" > "Input Source" > "Radio Fre-
quency" > "Test Setup"
The RF Input is the default input source.
A typical test setup for measurements over the RF input depends on the selected mea-
surement and the equipment used in the test setup. A schematic representation of
such a setup is provided in the dialog box.
●
The DUT directly sends a signal to the RF input of the R&S FSPN.
●
If necessary, the R&S FSPN can supply the DUT with power over the DC ports.
For more information about configuring the DC ports used in the setup, see Chap-
ter 6.6, "DC Source Configuration" , on page 123.
The remote commands required to configure the frequency are described in Chap-
ter 11.6.1.1, "RF Input" , on page 337.
