Screen Annotation
trigger mode. The second letter (“S”) indicates the cable TV analyzer is in
single-sweep mode.
Item 22 refers to the trace modes of the cable TV analyzer. The first letter
(“W”) indicates that the cable TV 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 (“S”).
Refer to
Table
2-l
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.
The display will be compressed slightly when using the PAL or NTSC format
for the MONITOR OUTPUT, instead of the normal format. The PAL and NTSC
formats have less vertical resolution than the cable TV analyzer display. The
top and bottom of the cable TV analyzer display are compressed slightly so
that all of the information can be fit into the size required by the MONITOR
OUTPUT.
