Accumulation (Accumulate)
When you turn the accumulate feature on, the instrument acquires waveforms at a rate independent of the
screen update interval and accumulates them on the screen.
The accumulated waveforms are displayed with gradually decreasing intensity for the specified amount of
time. The accumulated display can be used to increase the waveform acquisition rate and retain waveforms of
infrequent phenomenon on the screen for a certain amount of time.
If accumulation is turned off, the screen is updated every time a trigger occurs, and waveforms are not
accumulated. The waveform acquisition rate never becomes faster than the screen refresh interval of the display,
but this is effective when you want to focus on the waveform acquired once.
Gradation Mode
You can set the gradation mode to one of the settings below. Gradation is not applicable to logic signals.
• Intensity
Indicates frequency using different intensity levels. The intensity range is 1 to 64.
• Color
Indicates frequency using different colors. Indicates 15 frequency levels using different colors that range from
blue to green to yellow to red to white starting with the lowest frequency.
• OFF
Does not accumulate waveforms.
Accumulation Time (Accum Time)
Sets the amount of time to retain waveforms on the screen.
Selectable range
100 ms to 100 s, or Infinite (Infinite)
• If you press CLR, the accumulated waveforms are cleared.
Notes about Waveform Accumulation
• Automated measurement of waveform parameters and GO/NO-GO determination are performed on the
most recent waveform.
• If you press RUN/STOP to stop waveform acquisition, accumulation stops. When you restart waveform
acquisition, all the waveforms are cleared, and accumulation starts from the beginning.
• 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.
• If you change the display format when accumulated waveforms are displayed, the instrument operates in
the following manner.
During accumulation: The instrument clears the screen and restarts from the beginning.
When accumulation is stopped: The instrument clears the waveforms and displays the most recent
waveform.
