Fast signal acquisition helps you avoid missing anomalies. However,
simple superimposed waveform displays only tell whether or not an
anomaly occurred. Such displays do not provide information about
when the anomaly occurred, what events occurred before the anomaly,
nor what happened after the anomaly. The DL9000's History memory
function allows you to view and analyze up to 2000 previously acquired
waveforms, even after the acquisition stops. This offers unparalleled
insight into waveform behavior and makes troubleshooting easier.
History memory advantage #1: Correlate events from multiple channels
Ex 1: Display shows superimposed history waveforms
(Up to 2000 waveforms can be saved in history memory)
History memory advantage #2: Determine sequence of events
|
History memory captures and saves waveforms before and after the anomaly;
thus providing insight into the cause and effect of the anomaly.
