Automated measurement can be performed on various measurement parameters on the
displayed waveform (within the display record length, see appendix 1). Up to 24000 values
of the results of automated measurements can be saved to a file (see section 12.10).
There are 27 types of measurement parameters (including the delay between waveforms).
Up to 12 parameters from the selected parameters of all the channels can be displayed.
Statistical processing can be performed on the automated measurement values
described above. The following five statistics can be determined on the two measured
values of automated measurement parameters.
• Maximum value (Max)
• Minimum value (Min)
• Average value (Avg)
• Standard deviation (Sdv)
• Number of measured values used in the statistical processing (Cnt)
Measurement range
The following three statistical processing methods are available.
• Normal Statistical Processing
Statistical processing is performed on all acquired waveforms that are displayed while
acquiring waveforms.
• Measurement per Cycle and Statistical Processing within the Measurement Range
The cycle of the displayed waveform is determined in order from the oldest data, the
selected parameters for automated measurement are measured on the data within
the cycle, and statistical processing is performed. The cycle is determined in the
same fashion as the Period for the waveform parameter. You can select whether to
apply the cycle of the specified waveform to all waveforms (CH1 to CH8 (4), Math1,
and Math2) or determine the cycle for each waveform (Own).
Measurement and statistical processing can also be performed on a single displayed
history waveform. Statistical processing is performed from the oldest data of the
displayed waveform in blocks of cycles.
