Figure 2-1 Process of Signal Track
Key Points:
 When Signal Track is turned on, the ST (Signal Track) icon
is highlighted
in the status bar at the left of the screen.
 If an active marker currently exists, when Signal Track is enabled, the
instrument will search for and mark the point (with no more than 3 dB
variation in amplitude) near the marker as well as set the frequency of this
point as the center frequency to hold the signal at the center of the screen.
 If no marker is currently active, when Signal Track is enabled, the instrument
will activate Marker 1, execute a peak search automatically and set the
frequency of the current peak as the center frequency to hold the signal 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; in Zero Span,
Signal Track is invalid.
