above the soft keys.
• For a description of the operation using a USB keyboard or
a USB mouse, see section 4.3.
Press START/STOP.
Waveform acquisition is in progress when the indicator above and to the right of the
key is illuminated. When waveform acquisition is stopped, the indicator is OFF and
“Stopped” is displayed at the upper left corner of the screen.
Explanation
When waveform acquisition is started, waveform data is stored to the acquisition
memory each time a trigger is activated, and the displayed waveform is updated. The
acquisition memory is divided by the specified record length, and the maximum number
of waveforms that can be acquired is retained. The past waveforms that have been
retained can be recalled and displayed using the history memory function when
waveform acquisition is stopped. For the procedure of recalling waveforms using the
history memory function, see section 10.1.
Operation When the Acquisition Mode Is Set to Averaging Mode
• Averaging is stopped when waveform acquisition is stopped.
• Averaging starts again when waveform acquisition is restarted.
START/STOP Operation during Accumulation
Accumulation is aborted when acquisition is stopped.
When acquisition is started, the accumulated waveforms up to that point are cleared, and
new accumulation is started.
Events that Disable the START/STOP key
• When remote mode is engaged using the communication interface.
• When printing, during auto setup, and while the storage medium is being accessed.
Note
• Pressing the FILE key or HISTORY key while acquiring waveforms stops waveform
acquisition.
• If you start waveform acquisition after changing the waveform acquisition conditions, the data
that had been stored in the acquisition memory up to that point is cleared.
•A snapshot function that keeps the current displayed waveform on the screen is also
available. You can update the display without stopping waveform acquisition (see section
8.6).
