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.
