A glitch is a rapid change in the waveform that is usually narrow
as
compared to the waveform. This oscilloscope has two modes of
operation that you can
use
for
glitch capture: peak detect and Autostore.
1 Connect a signal to
the
oscilloscope
and
obtain a stable display.
2 Find
the
glitch.
Use
peak detect for narrow pulses or glitches that require sweep speeds
slower than
50
.us/div.
•
To
select peak detect, press I
Display
1.
Next, press the
Peak
Det
softkey.

Peak detect operates at sweep speeds from 5 s/div to
50
,us/div.
When operating, the initials Pk are displayed in the status line in
inverse video.
At
sweep speeds faster than
50
,us/div, the
Pk
initials are not displayed in inverse video, which indicates that
peak detect is not operating.
