Accumulation (Accumulate)
Ordinarily, momentary waveform anomalies are difficult to recognize because the displayed waveform is updated
whenever the trigger is activated. In waveform accumulation, older waveforms remain while new waveforms
continue to appear.
• ON: Waveforms are accumulated.
• OFF: Waveforms are not accumulated.
Clearing Accumulated Waveforms
You can clear accumulated waveforms by selecting Clear Trace.
• Automated measurement of waveform parameters and GO/NO-GO determination are performed on the
most recent waveform.
• If you press START/STOP to stop waveform acquisition, accumulation stops. When you restart waveform
acquisition, accumulation resumes from the condition that it was in when it was stopped.
• When Accumulate is set to ON, you cannot change the settings of the history feature.
• When Accumulate is set to ON, even if you change the display format, the waveforms that are currently on
the screen are not cleared. To clear waveforms, press CLEAR TRACE.
• You cannot set accumulate to ON in the roll mode display.
• When you set accumulate to OFF, the accumulated waveforms are cleared. To redisplay the waveforms,
use the history feature, and select the record number of the waveforms that you want to display. You can
select only waveforms that have record numbers. You cannot display earlier waveforms.
• If the instrument does not trigger when the trigger mode is set to Normal, the waveform intensity is retained
until the next time the instrument triggers.
Manual Event (Manual Event)
Indicates the positions of manually input events. You can input manual events and display positions when:
• SD recording is being executed.
• In recorder mode.
You can input manual events by applying a low edge to the external start/stop input (EVNT) terminal. You can
enter up to 100 events. For the specifications of the EVNT terminal, see section 4.5 in the
Getting Started Guide
