Past waveform data (history waveforms) stored in the acquisition memory can be
displayed when waveform acquisition is stopped. You can display a specified history
waveform from the data (up to 4096 waveforms, or the number of triggers) stored in the
acquisition memory. The number of waveforms N that can be acquired and held as
history waveforms varies from 1 to 4096 depending on the record length and interleave
mode settings. The waveform currently displayed on the screen (newest waveform) is
counted as the 1st waveform, and up to N–1 waveforms in the past can be displayed.
You can search history waveforms that meet specified conditions when waveform
acquisition is stopped.
You can search history waveforms that pass or do not pass a specified search zone.
