Windowing
When you set the windowing softkey to enabled, the softkey menu at the left is displayed. Windowing is similar to the delayed sweep on analog oscilloscopes because it turns on an expanded time base. This expanded time base allows you to pinpoint and to horizontally expand a portion of the signal for a more detailed or high resolution analysis. It can also help you to make custom automatic measurements. Automatic measurements are made on the first occurrence of the event on the display. The windowing feature allows you to isolate individual events on the display for the automatic measurement. View View lets you select main or window. When you select window, the softkey menu at the left is displayed. Main Main displays the signal according to the scale and position settings, and a window marker is placed on the signal. The window marker defines the portion of the signal you plan to expand. However, the color highlight is not available when mask testing is turned on. The default color of the window marker is red, but you can change the window marker color in the display menu. Window Window expands and displays the portion of the signal that is outlined by the window marker. The amount of expansion depends on the window scale and window position settings.
