IM DL850E-01EN
There are three statistical processing methods:
• Normal statistical processing
While acquiring waveforms, the DL850E/DL850EV measures the measurement items and calculates the
statistics of the waveforms that it has acquired so far.
• Cyclic statistical processing (measurement and statistical processing are performed for each period)
The DL850E/DL850EV divides the waveform into periods starting at the left side of the screen (the oldest
waveform) and moving to the right side of the screen, measures the selected measurement items within each
period, and performs statistical processing on the measurement items.
• Statistical processing of history waveforms
The DL850E/DL850EV measures the measurement items and calculates the statistics of history waveforms.
Measurement and statistical processing begin with the oldest waveform.
GO/NO-GO Determination
This feature is useful for signal testing on production lines and for tracking down abnormal phenomena. The
DL850E/DL850EV determines whether the waveform enters the specified range. When the DL850E/DL850EV
returns a GO (or NO-GO) result, specified actions are performed.
Determination Methods
• Waveform Zone
The DL850E/DL850EV returns GO/NO-GO results based on whether waveforms leave or enter the zone that
you create using a base waveform.
The DL850E/DL850EV returns a GO or
NO-GO judgment according to the
determination condition.

• Waveform Parameter
Set the upper and lower limits for automated measurement values of waveform parameters. The DL850E/
DL850EV performs GO/NO-GO determination based on whether the values are within or outside of the limits.
Actions Performed according to Determination Results
The DL850E/DL850EV can print and save screen captures, save waveform data, beep, and send e-mails
according to the results of GO/NO-GO determination.
