Note: Pass/Fail testing against a mask is affected by
horizontal and vertical zooming of the mask trace. The test
will be made inside the area bordered by the parameter
cursors. Timebases of the mask and the trace under test
should be identical. For visual mask testing, a single-grid
display should be used when performing a single-trace
mask test, while a dual- grid display should be used for a
dual-trace test.
