9.1 Mask testing
Masks are used to determine whether the amplitude of a signal remains within speci-
fied limits, e.g. to detect errors or test compliance of digital signals.
9.1.1 About masks and mask testing
Masks
A mask is specified by an upper and a lower limit line. The signal must run inside these
limit lines, otherwise a mask violation occurs.
A new mask is created from an existing signal: Mask limits are created by copying the
envelope waveform, and the limits are moved and stretched. The result is a tolerance
tube around the signal that is used as mask.
