Press the ZOOM button to cycle through one of three display options:
• ZOOM positioned on the 0 IRE, 0 mV, or 0% graticule line
• ZOOM positioned on the 100 IRE or 700 mV (or 800 mV for Eye
Pattern), or 100% graticule line
• Normal
At each zoom position, the graticule scale and waveform displays expand to provide
more resolution around the zoom point.

Placing the Waveform Display in Line Select Mode

NOTE: When inputs A and B are selected simultaneously within the same pane, the Line
Select function is not available.
Pressing the LINE button enables the selected pane to monitor a single line
of a video signal. This enables Line Select to monitor individual areas of the
entire image. To view a line in Line Select mode:
1. Press the LINE button to place the selected waveform display pane in Line Select
mode. At the bottom-center of the display, the pane displays the Line number and
Odd or Even field, as shown in Figure 3-13.

3. Rotate the CURVED ARROW knob to select the line to be displayed.
When the panes are linked by the INPUT button, all WFM, VECT, and GAMUT panes
are selected when the LINE button is pressed. When a picture is displayed in one of the
panes, a marker across the picture approximates the displayed line position (± 1 line).

Waveform Cursor Selections

Cursors are available for precise measurement of waveform voltage and
waveform time. The Time Cursor indication is in the lower-right of the pane,
and the amplitude cursor indication is in the lower-left of the pane as shown
in Figure 3-14.
