Operating Manual 1173.6275.12 - 30 221
7.2 Configuring Cable and Antenna Tests
For valid measurement results, you need to specify the characteristics of the cable
under test like model or frequency range.
7.2.1 Selecting the Cable Model
To determine the speed of propagation, and therefore the precise distance to any
faults, you have to specify the cable model that you want to test.
The R&S FSH already comes with an assortment of predefined cable models that you
can use without doing anything. If you want to test a cable that is not listed, you can
also define cable models manually, either directly on the R&S FSH or with the "Cable
Model Editor" of the R&S FSH4View software package that is delivered with the
R&S FSH.
7.2.1.1 Selecting a Predefined Cable Model
► Press the MEAS key.
► Press the "Cable Config" softkey.
► Select the "Select Cable Model"
menu item.
The R&S FSH opens the file
manager to select the cable
model.
► Select the cable model that you
are testing.
► Confirm the selection with the
"Select" softkey.
The R&S FSH shows the currently selected cable model in the diagram header.
► Select the "Deselect Cable Model" item from the "Cable Config" menu if you want
to perform measurements without using a particular cable model.
