Index
There are three statistical processing methods:
• Normal statistical processing
While acquiring waveforms, the DL850/DL850V 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 DL850/DL850V 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 DL850/DL850V 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 DL850/DL850V determines whether the waveform enters the specified range. When the DL850/
DL850V returns a GO (or NO-GO) result, specified actions are performed.
Determination Methods
• Waveform Zone
The DL850/DL850V returns GO/NO-GO results based on whether waveforms leave or enter the
zone that you create using a base waveform.
Determination
area
The DL850/DL850V returns a GO or NO-GO
judgment according to the determination
condition.
Specified zone
• Waveform Parameter
Set the upper and lower limits for automated measurement values of waveform parameters. The
DL850/DL850V performs GO/NO-GO determination based on whether the values are within or
outside of the limits.
Actions Performed according to Determination Results
The DL850/DL850V can print and save screen captures, save waveform data, beep, and send
e-mails according to the results of GO/NO-GO determination.
