For more details see Chapter 8.3.3, "Keeping the Center Frequency Stable - Signal
Tracking", on page 364.
If activated, after each sweep, the center frequency is set to the maximum level of the
specified "Signal Track Trace" found within the searched "Tracking Bandwidth" .
If the signal level does not pass the "Tracking Threshold" , the center frequency is not
changed.

8.3.4 How To Define the Frequency Range
The following step-by-step instructions demonstrate how to configure the frequency
and span settings. For details on individual functions and settings see Chapter 8.3.2,
"Frequency and Span Settings", on page 360.
The remote commands required to perform these tasks are described in Chap-
ter 14.7.1, "Defining the Frequency and Span", on page 885.
To configure the frequency and span
Frequency and span settings can be configured via the "Frequency" dialog box. Signal
tracking is configured in the "Signal Tracking" tab of this dialog box.
1. To display the "Frequency" dialog box, do one of the following:
● Select "Frequency" from the "Overview" .
● Select the [FREQ] key and then the "Frequency Config" softkey.
● Select the [SPAN] key and then the "Frequency Config" softkey.
2. Define the frequency range using one of the following methods:
● Define the "Center Frequency" and "Span" .
● Define the "Start Frequency" and "Stop Frequency" .
● To perform a measurement in the time domain, define the "Center Frequency"
and select the "Zero Span" button.
● To perform a measurement over the entire available frequency range, select
the "Full Span" button.
● To return to the previously set frequency range, select the "Last Span" button.
8.3.5 How to Move the Center Frequency through the Frequency Range
In some cases it may be useful to move the center frequency through a larger fre-
quency range, for example from one harmonic to another.
1. In the "Frequency" dialog box, define the "Center Frequency Stepsize" . This is the
size by which the center frequency is to be increased or decreased in each step.
