Use the KS/ command to manually adjust the internal preselector tracking. Normally, preselector tracking is
automatically adjusted. (See PP and KS = .) However, the KS/ function is useful for adjusting preselector tracking
of unstable signals, such as drifting signals or pulse modulated signals.
To manually adjust tracking, execute KS/ and then use the spectrum analyzer data knob to peak the signal
response at the marker position. If no marker is on screen, KS/ automatically places a marker at the signal with
greatest amplitude.
When KS/ is executed, the active function readout displays a number, from B to 63, which corresponds to the
preselector frequency Changing the active function readout by 1, shifts the preselector tuning by 1.13 MHz.
Once the preselector tracking is altered with the data knob, tracking is no longer automatically adjusted. Executing
KS = is the only way to re-enable automatic preselector tracking.
