5 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.
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 waveform, and the limits are moved and
stretched. The result is a tolerance tube around the signal that is used as mask.
5.1 Accessing the Mask Mode
1. Press the [MODE] key.
2. Select "Mask".
The mask interface is displayed and mask testing is started if masks are already
defined and activated.
5.2 Mask Test Results
Mask testing checks all active waveforms for mask violation simultaneously.
The test result of the selected mask is shown in the result table in the upper left corner
of the display.
