SPAN X Scale
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.
