To select the display unit:
Press the AMPT key.
Press the RANGE softkey.
The R&S FSH will open the menu for selecting the
display ranges. The following display units are
available for distance-to-fault measurements: return
loss in dB, linear in %, standing wave ration (VSWR),
reflection coefficient (REFL COEFF (ROH)) and
reflection coefficient (REFL COEFF (mROH)). Select
the display unit you want by using the cursor keys or
the rotary knob.
Note:
In the case of return loss and linear display, scaling is
directly selected. In the case of all other units, a
window for selecting the display range scaling opens.
You can select a display range by using the cursor
keys or the rotary knob.
Confirm the selection by pressing the ENTER key or
the RANGE softkey.
The R&S FSH now shows a value such as the
reflection coefficient of the measured cable over the
cable length.
The R&S FSH can also list any cable faults. It displays the return loss and distance from the
measurement plane of all reflections that exceed a settable threshold.
Press the LIST VIEW softkey in the Distance to
Fault menu.
The R&S FSH opens the threshold value entry box and
also displays the threshold as a horizontal line across
the measurement diagram.
Set the threshold using the cursor keys (5 dB
steps), the rotary knob (1 dB steps) or the number
keys.
