Description:
When signal tracking is enabled, the analyzer adjusts the value of the center frequency to keep
the largest signal centered in the current frequency span. Selecting either INP1 or INP2 turns on
signal tracking.
INP1 turns on signal tracking and uses channel 1 input signal to determine center frequency.
INP2 turns on signal tracking and uses the signal on channel 2 to determine center frequency.
INP2 should not be selected unless the (optional) second channel is installed.
Note
Tracking is not possible when: averaging is on, manual sweep is active, analog or
digital demod is active, capture playback is active, or when ROUT:REC is RF2 or
COMB.
