At this point, you should be able to see that the scope is capturing an infrequent
glitch as shown in
. 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.
