PEAK
ZOOM
finds the highest displayed signal and narrows the span to a value selected
by the user. Pressing PEAK ZOOM the first time will make FINAL SPAN the
active function so the user can input the destination span. The current FINAL
SPAN value will be displayed. At that time the user can enter a span or press
PEAK ZOOM again to use the displayed span.
The peak zoom function sets the reference level to the signal amplitude and
sets the center frequency step size to the signal frequency. If the signal is in a
microwave band, a preselector peak is executed.
For a signal to be found it must have a peak of at least 6
dB.
If no signal is
found, Signal not found will be displayed. (The routine will ignore the
spectrum analyzer local oscillator feedthrough signal which is at 0 Hz.)

displays a list, of up to ten signal peaks, that is updated at the end of each
sweep. The peaks can be sorted in order by descending amplitude or by
ascending frequency. Peaks above or below the display line can be excluded
from the table. The peak table function works with trace A only. The peak
