Drawing is permitted only in the area between the markers and must be started in the marked area. Clicking and drawing outside of this area is ignored.

Tyt

The waveform edit window contains horizontal and vertical gridlines. To change the spacing of the horizontal and vertical grid lines select

III from the Menu Bar.

The spacing of the vertical (up/down) grid lines is directly affected by the

IIIcommand. the horizontal spacing (left/right) of the grid lines is automatically adjusted to standard values (such as 0, 0.25, 0.5, 0.75, or 1.0).

Grid line spacing is specified in terms of the number of of screen display pixels between grid lines. While this spacing also relates to the number of waveform data points displayed between grid lines, the relationship is not always one-to-one due to the effects of zooming. Six levels of zooming are provided (0 - 5). Refer to the discussion on page 53 for more information about the grid settings.
