To edit the mask to test only a portion of a waveform
In certain circumstances, not all the points on the waveform need to be
tested. Only the area of interest needs to be tested. For example, to test the
amount of overshoot of a pulse, you only need to test the portion of the
waveform after the rising edge. You can select the test region by editing the
shape of the mask template.
