Zoom/Pan – A dedicated, two-tier
front-panel knob provides intuitive
control of both zooming and panning.
The inner knob adjusts the zoom factor
(or zoom scale); turning it clockwise
activates zoom and goes to progres-
sively higher zoom factors, while turning
it counter-clockwise results in lower
zoom factors and eventually turning
zoom off. The outer knob pans the
zoom box across the waveform to
quickly get to the portion of the wave-
form you are interested in. The outer
knob also utilizes force-feedback to
determine how fast to pan on the
waveform. The farther you turn the
outer knob, the faster the zoom box
moves. Pan direction is changed by
simply turning the knob the other way.
No longer do you need to navigate
through multiple menus to adjust your
zoom view.
Play/Pause – A dedicated play/pause
button on the front panel scrolls the
waveform across the display automati-
cally while you look for anomalies or an
event of interest. Playback speed and
direction are controlled using the intu-
itive pan knob. Once again, turning the
knob further makes the waveform scroll
faster and changing direction is as simple
as turning the knob the other way.
User Marks – See something interesting
on your waveform? Press the Set Mark
button on the front panel to leave one
or more “bookmarks” on the waveform.
Navigating between marks is as simple
as pressing the Previous <— and Next
—> buttons on the front panel.
Search Marks – Don’t want to take the
time to inspect the entire acquisition to
find the event you’re looking for? The
DPO4000 Series features a robust
waveform
search feature that allows you
to search through your long acquisition
based on user-defined criteria. All occur-
rences of the event are highlighted with
search marks and are easily navigated to,
using the front panel Previous <— and
Next —> buttons. Search types include
edge, pulse width, runt, logic, setup and
hold, rise/fall time and I
