AC Line Dropout
To perform an ac line dropout, select Dropout in the Tests menu. The test uses
the parameters that you enter in the following dialog box. This box is displayed
on the screen when the test is first selected.
You can use the transient editor to make any final adjustments to the ac line
dropout test such as fine tuning the width of the dropout, or positioning and
enabling the measurement trigger.
When measurements are enabled, you can view the line dropout measurement in
the Main window. If necessary, move the Transient editor out of the way to see
the Main window.
