 For measurements on devices under test which
require an external voltage supply (e.g. power
amplifi ers), connect the supply voltage from a
suitable AC power supply to the BIAS PORT 1
input.
 Connect the RF test cable supplied with option
R&S FSH-Z20 to PORT 1.
The RF test cable must be used. Results
are invalid without this cable.
 Press the MODE key.
 Press the DISTANCE TO FAULT softkey.
The R&S FSH switches on the distance-to-fault
measurement function.
The R&S FSH delivers optimum results if the
center frequency is set to the frequency at which
the device under test is operated.
 Press the FREQ key.
 Input the center frequency (CENTER), e.g.
frequency of the antenna at the end of the cable
under test.
To perform distance-to-fault cable measurements,
the R&S FSH needs to be informed about the type
of cable and its approximate length. Frequency-
dependent cable models can be generated with the
supplied ”R&S FSH4 View” software for Windows
and loaded onto the R&S FSH. The procedure is
described in the R&S FSH View manual.
