Set Gates

Optionally, set gates to limit the portion of the waveform that is compared to the mask.

1. Touch the Gates tab to display the dialog.

2. Enter the Start and Stop timebase divisions that mark the segment of the waveform to be tested with

this mask. This can be a whole division of a fraction of a division. Divisions are numbered 1-n left to
right.

Tip: A quick way to position the gate is to touch the gate posts, which initially are placed at the
extreme left and right ends of the grid, and drag them to the desired points.

Define Test

1. Touch the Test tab to display the dialog.

2. Select one of the conditions that, when True (yes), result in a Pass.

3. Optionally, turn Off/On markers. Markers visually indicate where on the waveform mask violations

have occurred.

Removing a Mask from the Display

1. Access the Mask dialogs.

2. On the Load Mask right-hand dialog, click the Delete button.
