► Press [MARKER] key.
The R&S Spectrum Rider activates a marker and puts it on the maximum
value on the trace. The coordinates of the marker are shown in a table above
the measurement diagram.
A red vertical line represents the position of the marker on the horizontal axis
(i.e. the frequency). A small red horizontal dash represents the marker posi-
tion on the vertical axis (i.e. the level).
Measuring the frequency
The trace consists of 711 measurement points (frequency points). The marker is
always positioned on one of these measurement points. The R&S Spectrum
Rider calculates the marker frequency from the frequency of the measurement
point, the center frequency and the frequency span that have been set. The mea-
surement-point resolution, and consequently the accuracy of the marker fre-
quency readout, therefore depend on the frequency span that has been selected.
The R&S Spectrum Rider has a frequency counter to increase the accuracy of the
marker-frequency readout. It completes the sweep, then counts the frequency at
the marker position.
1. Press the "Marker Function" softkey at the "Parameter view".
2. Select the "Frequency Count" from the menu item.
