SPAN X Scale
Zone Span Allows the span of the zone markers to be changed
without changing the center frequency. The zone
markers are vertical lines marking the zone in the
upper window. They determine the frequency range
displayed in the lower window. As the zone markers are
moved, the span of the lower window is changed but the
lower window will not be updated to reflect the change
unless it is selected as the active window.
(See
Zone On Off.)
The span limit of the lower window is the same as the
span limit of the analyzer. The span for the lower
window is not limited to the selected span of the upper
window. However, if the frequency span of the lower
window is outside of the span of the upper window, the
vertical span markers will not be displayed. When the
lower window is active, the
SPAN X Scale key will
change
Zone Span, and any change to Zone Span while
the lower window is active, will change the span.

SPAN X Scale, Zone
Zone Pk Right
Finds the next peak to the right of the zone center
frequency on the upper window trace and then moves
the zone so that it is centered around the new peak. The
zone span is not changed. The center frequency of the
lower window changes to reflect the new zone center
frequency. The lower window will not be updated until
it is made active. If no peak is found, the zone will not
be moved. A signal must obey the parameters defined
in
Search, Search Param to be identified as a peak
signal. Pressing Zone Pk Right will have no effect if the
upper window is not the active window or if it is in zero
span.

Zone Pk Left
Finds the next peak to the left of the zone center
frequency on the upper window trace and then moves
the zone so that it is centered around the new peak. The
zone span is not changed. The center frequency of the
lower window changes to reflect the new zone center
frequency. The lower window will not be updated until
it is made active. If no peak is found, the zone will not
be moved. A signal must obey the parameters defined
in
Search, Search Param to be identified as a peak
signal. Pressing Zone Pk Left will have no effect if the
upper window is not the active window or if it is in zero
span.
