5. To stretch or compress the selected mask segment, enter the "X-Factor" for hori-
zontal scaling and the "Y-Factor" for vertical scaling. The x-values and y-values of all
points are multiplied with the corresponding factor. Factors >1 stretch the mask seg-
ment, while factors between 0 and 1 compress it. Negative values are possible and
change the algebraic sign.
6. To move the selected mask segment, enter the "X-Offset" for horizontal direction and
the "Y-Offset" for vertical direction. The specified offset is added to the corresponding
values of all points.
7. Tap "Recalculate" to perform the scaling and/or move.
8.2.2 Setting Up a Mask Test
In addition to the mask definition, the mask test contains further settings:
the waveform to be tested
the criteria for a failed test
the actions to be taken if a test has failed or has been completed successfully
1. Press the MASKS key on the front panel.
2. Select the "Test Definition" tab.
3. Select the "Source" to be tested.
4. Set the conditions for a failed test:
a) Fail condition: select if sample hits or the number of acquisitions with sample hits
are considered.
b) Violation tolerance: 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
violation tolerance hits.
5. Select the "Event Actions / Reset" tab.
6. For each action, select when the action will be executed:
"On violation" if the mask test has failed
"On successful completion"
