4.2.7.4 Tracking signal
The signal tracking function is very useful for the slow drift signal, which enables the drift signal to be the
center of the display screen.
It should be noted that the signal tracking is to track the unstable signals, rather than track the signals until the
center frequency of the Series Signal Analyzer is changed. Make sure the tracked signal is correct when the
center frequency of the analyzer is changed.
Step 1. set the output signal of the signal generator with frequency of 300 MHz, amplitude of -20dBm,
and stepped frequency of 100kHz, and open its RF output.
Step 2. set the analyzer as spectrum analysis mode:
 Press
【
Mode
】
and [Spectrum].
Step 3. set center frequency to be 1 MHz of frequency offset for the Series Signal Analyzer:
 Press 【 Preset 】 .
 Press
【
Frequency
】
, [Center Freq] and enter 301 MHz.
 Press
【

】
, [Span] and enter 10 MHz.
Step 4. open the signal tracking:
 Press 【 Frequency 】 and [Signal Track On Off].
It should be noted that the marker will be placed in the max peak amplitude, and then the signal is displayed in
the center of the analyzer, and the center frequency will be automatically adjusted for each scanning.
Step 5. open the Delta Marker function:
 Press

and [Delta Marker].
