Selecting the measurement port
In the default state, port 1 (RF input) already is the measurement port.
To select the measurement port manually,
► Press the MEAS key.
► Press the "Meas Mode" softkey.
► Select the "DTF / Refl Measurement Port" menu item.
► Select the port you want to perform the measurement on.
Setting the frequency
To get the best results, you should adjust the center frequency to that of the DUT.
► Press the FREQ key.
► Press the "DTF Center Freq" softkey.
► Enter the center frequency you need (for example that of the antenna at the other
end of the cable) with the numeric keys.
The R&S FSH automatically calculates the best bandwidth for the current
measurement.
Specifying the cable model
To perform cable tests, you have to specify the type of the cable and its approximate
length.
► Press the MEAS key.
► Press the "Cable Config" softkey.
► Select the "Select Cable Model…" item.
The R&S FSH opens a dialog box to select the cable model.

The currently active cable model is always shown in the display header.
