At this point, you should be able to see that the scope is capturing an
infrequent glitch as shown in Figure 19. This particular glitch occurs just
once every 1,000,000 cycles of the clock signal that we are triggering on.
Because this scope can update waveforms as fast as 1,000,000
waveforms/sec, the scope can capture the glitch on average once per
second. Let’s now use the scope’s Mask Test capability to analyze this
glitch.
9 Press [Analyze].
10 Press Features Mask two times to turn on mask testing.
11 Press Automask.
12 Press Create Mask to automatically create a pass/fail mask around this
waveform.
