pulsus
Use
Autostore for the following cases: waveforms that are
changing, waveforms that you want to view and compare with
stored waveforms, and narrow pulses or glitches that occur
infrequently but require the use of sweep speeds outside the
range of peak detect.
• Press J
Autostore
I .
You
can use peak detect and Autostore together. Peak detect
captures the glitch, while Autostore retains the glitch on the
display in half bright video.
3 Characterize
the
glitch
with
delayed sweep.
Peak detect functions in the main sweep only, not in the delayed sweep.
To
characterize the glitch with delayed sweep
follow
these steps.
• Press I
Main/Delayed
J.
Next press the
Delayed
softkey.
•
To
obtain a better resolution of the glitch, expand the time base.
•
To
set the expanded portion of the main sweep over the glitch, use
the Delay knob.
•
To
characterize the glitch, use the cursors or the automatic
measurement capabilities of the oscilloscope.
