3.9 Starting and Stopping Waveform Acquisition
Procedure
Starting and Stopping Waveform Acquisition
1.
Press RUN/STOP.
• The RUN/STOP key illuminates, and waveform acquisition starts. The acquired waveform is
displayed.
• If you set the record length to a value that allows only one waveform to be acquired, pressing the
RUN/STOP key will produce the same result as pressing the SINGLE key.
2.
Press RUN/STOP again.
The RUN/STOP key light turns off, and waveform acquisition stops.
Acquiring a Single Waveform
Press SINGLE.
• The SINGLE key illuminates, and waveform acquisition starts. The acquired waveform is displayed.
• The trigger mode is set to Single mode, and the instrument acquires a waveform.
• When the instrument triggers, it acquires and displays only one waveform and then stops waveform
acquisition. The SINGLE key light turns off.
• To stop waveform acquisition, press RUN/STOP.
Explanation
Waveform Acquisition and Indicators
• When the RUN/STOP key or SINGLE key is illuminated, the instrument is acquiring waveforms.
“Running” appears in the upper right of the screen.
• When the RUN/STOP key or SINGLE key is not illuminated, waveform acquisition is stopped.
“Stopped” appears in the upper right of the screen.
Instrument Operation When the Acquisition Mode Is Set to
Averaging
• Averaging stops when you stop waveform acquisition.
• If you restart waveform acquisition again, averaging starts from the beginning.
Running and Stopping Operations during Accumulation
• Accumulation stops when you stop waveform acquisition.
• If you restart waveform acquisition, past waveforms are cleared, and accumulation starts over.
Note
• If you start waveform acquisition using RUN/STOP, past data stored in the acquisition memory is cleared.
• You can use the snapshot feature to retain the displayed waveform on the screen. This feature allows
you to retain the waveform that you have taken a snapshot of on the screen while the instrument
continues signal acquisition.
• If you change the settings related to waveform acquisition conditions, such as the vertical axis, horizontal
axis, and trigger, while waveform acquisition is stopped, the changes take effect the next time waveform
acquisition is executed.
However, if you change the vertical scale, vertical position, time scale, trigger position, or the like, the
waveform is expanded, reduced, or moved, and a preview is displayed with the waveform acquisition
stopped.
