Figure 2-4. Screen Annotation
In Figure 2-4, item 21 refers to the trigger and sweep modes of the spectrum analyzer. The first
letter (“F”) indicates the spectrum analyzer is in free-run trigger mode. The second letter (“S”)
indicates the spectrum analyzer is in single-sweep mode.
Item 22 refers to the trace modes of the spectrum analyzer. The first letter (“W”) indicates that
the spectrum analyzer is in clear-write mode. The second letter is “A,” representing trace A.
The trace B trace mode is “SB”, indicating trace B (“B”) is in the store-blank mode (“S”). The
trace mode annotation for trace C is displayed under the trace mode annotation of trace A. In
Figure 2-4, the trace C trace mode is “SC”, indicating trace C (“C”) is in the store blank mode
(‘is’).
Refer to Table 2-3 for the screen annotation codes for trace, trigger, and sweep modes.
The WINDOWS display mode splits the screen into two separate displays. Only one of these
displays is active at a time. The currently active window will have a solid line around the
graticule rather than a broken line. The complete annotation is not available for each window
because of space limitations.
