Definition type
Sets the method of mask definition.
"User"
The mask is created manually by tapping the mask points on the touch
screen and/or by entering the numerical x- and y-values of the mask
points.
"Waveform"
The mask is created from an existing waveform. The envelope of the
waveform builds the upper and lower limit line of the mask, and the limits
are moved and stretched. The result is a tolerance tube around the
waveform that is used as mask.

Fail condition, Violation tolerance
The fail criteria for a mask test is set by two parameters: "Fail condition" and "Violation
tolerance".
"Fail condition" defines the kind of hits to be considered for test evaluation:
●
"Samples": Considers the number of samples that hit the mask.
●
"Acquisitions": Considers the number of acquisitions that contain at least one sample
hit. How many samples hit the mask in that acquisition is not relevant.
"Violation tolerance" sets the number of tolerable sample hits or acquisition hits.
A test has failed if the number of sample hits or acquisition hits exceeds the limit of vio-
lation tolerance hits.
Example:
The example test has failed when the sixth acquisition violated the mask.
