Using Markers
The
Measurement Result View
shows the horizontal position of all markers and the
corresponding vertical value.
You can select any marker in the
Measurement Result View
for further marker function
using the marker softkey menu.
7.3.2.1
Using Markers and Deltamarkers
The R&S Cable Rider ZPH has six markers, five of which can be used as either mark-
ers or delta markers.
The markers cannot leave the trace and indicate the horizontal and vertical coordinates
of the point they are positioned on. The horizontal position of a marker is shown by a
vertical line which extends from the top to the bottom of the measurement diagram.
The marker list above the diagram area shows the exact coordinates of all markers in
use.
When measuring the distance-to-fault, the horizontal unit is meter or feet. For all other
measurements the horizontal axis is the frequency axis. The unit of the vertical axis is
dB for distance-to-fault and cable loss measurements and dBm for all others.
The position of a delta marker is indicated by a dashed line to distinguish it from a nor-
mal marker. The delta marker level is always a relative to the main marker level and so
the delta marker level unit is always dB. The delta marker frequency is always relative
to the main marker – in other words, the delta marker frequency is the frequency differ-
ence between the frequency at the point marked by the main marker and the frequency
at the point marked by the delta marker.
To measure complex signals, you can activate up to six markers. Marker 1 is always a
normal marker and the reference of all delta markers. Markers 2 to 6 are either mark-
ers or delta markers depending on your setup.
