8.3.2 Mask Definition
With mask definition, you define the shape of the mask - the form and position of its limit
lines. The content of the "Mask Definition" tab depends on the selected "Definition
type": "User" or "Waveform".
The "Definition type" is a common setting on the top of the tab, see "Definition
type" on page 226.
Below, you find the specific settings:
8.3.2.1 Mask Definition: User Mask
A user mask is defined by entering the time and voltage values for all corner points of the
mask segments. A user mask has at least one segment. Complex masks can have up to
16 segments.
An inner segment is an area defined by three or more points. Upper and lower segments
limit the signal on top and bottom of the screen. They are defined by a line, the region
above or below the line is set automatically as mask segment.
Alternatively, you can set the corner points on the touch screen and adjust the values in
the "Mask Definition" tab.
To save the mask, select the "Test Definition" tab and save the mask test.
