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.
