Windows display mode splits the cable TV analyzer display into two frequency or time displays.
When windows is first turned on, the top window will contain an inactive copy of the previous display. The lower window will be active and will display a subset of the frequency span of the upper window. The span of the lower window will be indicated on the upper window by two vertical lines called zone markers. The zone markers can be moved using the zone center and zone span softkeys to look at different portions of the upper window span.
The instrument state of the active window can be changed without affecting the state of the inactive window. The state of the active window will be used as the state of the cable TV analyzer for sweeping and updating trace data.
