Reference
Single Button.
Push the Single button when you want the oscilloscope to acquire
a single waveform and then stop. Each time you push the Single button, the
oscilloscope begins to acquire another waveform. After the oscilloscope detects a
trigger it completes the acquisition and stops.
Acquisition mode Single button
Sample, Peak Detect Sequence is complete when one acquisition is acquired.
Average
Sequence is complete when the de fi ned number of
acquisitions is reached; (See page 93, Acquire .)
Scan Mode Display.
You can use the Horizontal Scan acquisition mode (also
called Roll mode) to continuously monitor signals that change slowly. The
oscilloscope displays waveform updates from the left to the right of the screen and
erases old points as it displays new points. A moving, one-division-wide blank
section of the screen separates the new waveform points from the old.
The oscilloscope changes to the Scan acquisition mode when you turn the
Horizontal
Scale knob to 100 ms/div or slower, and select the Auto Mode option
in the Trigger Menu.
To disable Scan mode, push the Trig Menu button and set the Mode option to
Normal.
Stopping the Acquisition.
While the acquisition is running, the waveform display
is live. Stopping the acquisition (when you push the Run/Stop button) freezes
the display. In either mode, the waveform display can be scaled or positioned
with the vertical and horizontal controls.
Application
You can use the Application button when an Application Key is inserted in the
front of the oscilloscope, such as for power analysis. For more information, refer
to the user manual for the application.
Autorange
When you push the AutoRange button, the oscilloscope activates or deactivates
the Autorange function. An LED light turns on adjacent to the AutoRange button
that indicates when the function is active.
This function automatically adjusts setup values to track a signal. If the signal
changes, the setup continues to track the signal. When you power on the
oscilloscope, autoranging is always inactive.
