Using Pattern Masks
To activate and select masks:
1. From the Settings menu, select Acquisition.
2. Under the Analysis tab, select the desired mask types and masks.
The drop-down lists correspond to available mask definition files,
either provided with the application or custom-made.
3. Click Apply to confirm your settings, or OK to also close the window.
Note: The eye period is automatically set to 1 (and cannot be changed) when an
intensity or EVM mask is active, no matter if masks are actually shown.
To show or hide masks on the graphs:
1. From the Display menu, select Masks > Show/Hide Masks.
2. Optionally select Highlight points in masks in the same menu. Points
in error will be displayed in bright red.
Note: You can show or hide masks at any time, even while an acquisition is in
progress. All masks are shown or hidden at once.
