Description
ZMKPKNL does the following:
1. Searches for the next signal peak outside and to the left of the zone marker. ZMKPKNL only
applies if the window is in a non-zero span; ZMKPKNL does not apply if the window is in
the time domain.
2. If a peak is found, ZMKPKNL moves the zone marker so that it is centered around the peak.
If a signal peak cannot be found, or the window is in zero span, the zone marker is not
moved.
3. Changes the center frequency of the lower window to the frequency of the signal peak.
‘Ib be considered a signal peak, the signal must be greater than the peak excursion (see
“MKPX” for more information about the peak excursion).
ZMKPKNL should only be used when the windows display mode is turned on.
