R&S FSH with VSWR Bridge
R&S FSH-Z2
Connect the control cable of the R&S FSH-Z2 or R&S FSH-Z3 to the power sensor connector of the
R&S FSH.
Connect the RF and generator port of the R&S FSH-Z2/R&S FSH-Z3 to the RF input and generator
output of the R&S FSH.
Connect the 1 m test cable supplied with option R&S FSH-B1 to the bridge test port.
Note:
The 1 m cable must be used. Results are invalid without this cable.
Press the MEAS key.
Press the MEASURE softkey.
Using the cursor keys or rotary knob, select DISTANCE TO FAULT from the menu and confirm with
the ENTER key or the MEAS 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, e.g. frequency of the antenna at the end of the cable under test.
