Waveform Analysis/Search
Displaying History Waveforms <Section 11.1>
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 2000 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 2000 depending on the record length and acquisition mode settings. The
waveform currently displayed on the screen (newest waveform) is counted as the 1
st
waveform, and up to N–1 waveforms in the past can be displayed.
History Search Function <Sections 11.2 and 11.3>
You can search waveforms that match specified conditions from the waveform data in
the history memory.
Search by Zone
From the waveforms stored in the history memory, waveforms that passed or not passed
a specified area (zone) can be searched.

Selected Record No. 0
Selected Record No. –25
Specified area
Detects the waveform that
passed through the specified area
Search by Waveform Parameters
From the waveforms stored in the history memory, waveforms that meet or do not meet
the specified parameter conditions can be searched.
