100 ns wide. Let’s set up the scope to uniquely trigger on the positive
runts that are < 200 ns wide. In other words, let’s isolate the smaller of
these two runts.

Your scope’s display should look similar to
showing a positive
runt pulse that is approximately 100 ns wide near center- screen. In
addition to triggering on runt pulse conditions, the Agilent 3000 X- Series
oscilloscopes can also perform
Search & Navigation
to find multiple runt
pulse conditions, regardless of the specific trigger setup condition. Let’s
now capture a longer stream of pulses and perform an automatic search
operation to find all runts.

Set the scope’s timebase to
100.0 µs/div
