7 Acquisition Modes

Starting, Stopping, and Single Acquisitions (Run Control)
To start and stop an acquisition
• When you press the [Run/Stop] key, it illuminates in green and the
oscilloscope is in run mode.
The oscilloscope examines the input voltage at each probe, and updates
the display whenever the trigger conditions are met. Trigger processing
and screen update rate are optimized based on the oscilloscope settings.
The oscilloscope displays multiple acquisitions of the same signal
similar to the way an analog oscilloscope displays waveforms.
• When you press the [Run/Stop] key again, it illuminates in red, and the
oscilloscope is stopped.
“Stop” is displayed in the trigger mode position in the status line at the
top of the display. You can pan and zoom the stored waveform by
turning the horizontal and vertical control knobs.
When the oscilloscope is running and you press the [Run/Stop] key, it will
flash until the current acquisition is completed. If the acquisition
completes immediately, the [Run/Stop] key will not flash.
At slower sweep speeds, you may not want to wait for the acquisition to
finish. Just press [Run/Stop] again. The acquisition will stop immediately
and a partial waveform will be displayed.
You can display the results of multiple acquisitions using infinite
persistence. See “To set or clear infinite persistence” on page 85.
