View/Display
Transition Rules
When you enter the Trace Zoom view, the top window of Trace Zoom takes on all of the traces,
markers and settings that were present in the Normal View. The Zoom Center is the same as the
analyzer Center Frequency, and the Zoom Span is 10 % of the analyzer Span. When you leave the
Trace Zoom View, the top window traces and settings carry over to the next view.
When you enter the Trace Zoom view, the focus is always in the zoom window. To change the
focus (switch between windows), press the Next Window key located below the display. The
window which has the focus is distinguished by a green border.
Zone Span
In the Zone Span view, the screen is split into two windows. The top window is a normal
spectrum analyzer window, and the bottom window (“Zone Window”) shows a window whose
span represents a region (zone) within the top window. The data in the two windows represents
two completely separate sweeps; each window sweeps only when the focus (thick green border) is
on that window. It is important to understand that the data in the window without the focus
remains unchanged until the focus is moved to that window.
In the top window, the zone region is indicated by a light orange shading and solid orange
boundary lines. The Zone Window is not shaded orange; this emphasizes the fact that, unlike
Trace Zoom, the data in the Zone Window does not match the top window but is from a separate
sweep. You can set the span of the Zone Window using the Zone Span key (in the Span menu)
and you can set the Center Frequency of the Zoom Window using the Zone Center key (in the
Frequency menu).
Note that in Zone Span, the Span of the top window cannot go below 10 Hz. The Zero Span key is
grayed out when the top window is active. The Last Span key will do nothing if the last span
was zero span. If, on entry to Zone Span, the Span is 0 Hz, the Span will revert to the last
nonzero span. Also, if the Span of the top window is between 10 Hz and 100 Hz on transition,
the Zone Span will initialize to 10 Hz, not 10% of Span.

Example DISP:VIEW ZSP
Example Zone Span is a View in the X-Series, whereas in the ESA it was under the Span menu. There
were no remote commands associated with Zone Span in the past so there are no code
compatibility issues.
Dependencies Because Zone Span is a split-screen View, no other split screen views are available in Zone
Span. These include Peak Table, Marker Table, and the Limit and Ampcor editors. The keys that
access these functions are grayed out while in Spectrogram.
Also in the Zone Span View, Signal Track is not allowed and is grayed out
