Setting and Using the Measurement Functions R&S FSH3
Locating cable faults by means of the marker function
The distance to cable faults or the distance between any two faults can also be read off with the marker.
¾ Press the MARKER key.
The R&S FSH3 opens the marker menu and places
the marker on the fault with the largest reflection. The
marker readout gives the distance of the fault from the
measurement plane in meters and its return loss.
The marker that indicates the distance from the
measurement plane is renamed the DISTANCE
MARKER. It is activated for entry (DISTANCE value
entry box).
¾ Change the distance marker by entering a number,
adjusting the rotary knob (pixel by pixel) or by
using the cursor keys (step = 10 % of the span).
The reference plane to which the distance of a
reflection is referred can be redefined using the marker
offset.
¾ To define a new reference plane for the marker,
press the MARKER OFFSET softkey.
The R&S FSH3 turns on the distance marker
(OFFSET) and places it on the start of the trace. The
offset marker readout box displays the distance from
the measurement plane in meters and the return loss.
The main marker (Dist) now gives the distance from
the marker offset.
The marker readout label indicating the distance from
the main marker is renamed the Offset. It is activated
for an entry (OFFSET entry box).
¾ Change the offset marker by entering a number,
adjusting the rotary knob (pixel by pixel) or by
using the cursor keys (step = 10 % of the span).
