Acquiring Waveforms
You can choose to acquire a single waveform or to acquire waveforms
continuously. If you want to acquire a single waveform, press the SINGLE front
panel button. Each time you press the SINGLE front panel button, the
oscilloscope begins to acquire another waveform. After the oscilloscope
detects a trigger, it completes the acquisition and stops. If you want to acquire
waveforms continuously, press the RUN/STOP front panel button. Press the
button again to stop the acquisition.
When you start an acquisition, the oscilloscope goes through the following
steps:
1. Acquires enough data to fill the portion of the waveform record to the
left of the trigger point (pre-trigger).
2. Continues to acquire data while waiting for the trigger condition to
occur.
3. Detects the trigger condition.
4. Continues to acquire data until the waveform record is full.
5. Displays the waveform.
Changing the Timebase
The oscilloscope digitizes waveforms by acquiring the value of an input signal
at discrete points. The timebase allows you to control how often the values
are digitized. You can change the timebase using the Time/div front panel
knob in the Horizontal Control group.
NOTE: As you turn the Time/div front panel knob, the value is displayed at the
lower-center of the display as described in Understanding Display Information
(on page 19).
Zooming Waveforms
The Delayed option button on the Horizontal menu (or pressing the Time/Div
Front Panel (on page 7) knob) toggles between a state where the display
provides a split-screen layout where an upper trace shows the actual
waveform with a shaded, mask-like portion covering the non-zoomed portion
of the waveform; the lower trace displays the actual zoom segment. While in
this view, turn the Push Zoom Front Panel (on page 7) knob to adjust the
zoom portion of the trace.
