Run/Stop Button. Push the Run/Stop button when you want the oscilloscope to
continuously acquire waveforms. Push the button again to stop the acquisition.
Single Button. Push the Single (single sequence) 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.

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.
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.
