Configuring the Horizontal Axis
The [FREQ/DIST] key contains all necessary functions to configure the horizontal axis
for spectrum measurements.
The contents of the menu depend on the currently selected measurement.
Usually, the horizontal axis contains frequency information in spectrum mode. You can
specify the frequency in terms of the center frequency or by defining a start and stop
frequency for a particular span.
If you know the frequency of the signal you are measuring, it is best to match the cen-
ter frequency to the signal's frequency. If you are investigating signals, e.g. harmonics,
that are within a particular frequency range, the best option is to enter a start and stop
frequency to define the span.

Defining the Center Frequency
The center frequency represents the frequency at the center of the horizontal axis in
the diagram area.
1. Press the [FREQ/DIST] key.
2. Select the "Center Freq" softkey.
The R&S Cable Rider ZPH opens an input field to define the center frequency.
3. Enter the center frequency you need.
The frequency you have entered becomes the new center frequency.
