Figure 2-1 Signal Tracking Process 
Remarks: 
  If an active marker currently exists, when Signal Track is enabled, the 
instrument will search for and mark the point (whose amplitude variation is less 
than 3 dB) near the marker. Then, set the frequency at this point to be the 
center frequency to keep the signal at the center of the screen. 
  If no marker is currently active, when Signal Track is enabled, the instrument will 
activate Marker1, execute a peak search automatically, and set the frequency 
value at the current peak to be the center frequency to keep the signal always 
displayed at the center of the screen. 
  In continuous sweep, the system tracks the signal continuously; in single sweep, 
the instrument only performs a single signal track. 
  The signal tracking function is only applicable to the swept analysis. The signal 
tracking function is invalid in the following conditions: 
— In zero span mode; 
— When the tracking generator is enabled; 
— When the trace is not updated; 
— When the continuous peak search is enabled; 
— In advanced measurement mode.
