Introduction to Main Functions
Automatic Measurement of Waveform Parameters
User’s manual section 10.6, “Automatic Measurement of Waveform Parameters”
This function automatically measures certain properties of a waveform such as the maximum level and frequency.
There are 27 parameters that can be measured (including between-waveform delay). Up to 12 of those parameters
can be displayed on the screen. From all waveforms, up to 24000 data items total can be saved to a storage
medium.
Measured items related to the
vertical axis:
10
Measured items related to the
time axis:
12
Measured items related to the
area:
4
Delay between waveforms
Measured items having to do with
the time difference between the
rising and falling of the target
waveform relative to a reference
waveform or trigger point.
Statistical Processing
User’s manual section 10.7, “Performing Statistical Processing of the Measured Values of Waveform Parameters”
The following five results of statistical processing are performed on the same two measured items from automatic
measurement of waveform parameters.

Results of statistical processing
The following three types of statistical processing are available.
Measurement per cycle/statistical processing within the measurement range
Waveforms are delimited every cycle from the left side of the screen to the right (oldest to
youngest), then each cycle is measured for the selected measurement item and statistics are
calculated.
Normal measurement/statistical processing
During measurement, all waveform data acquired up to the current time are measured for the
selected measurement item and statistics are calculated.
Measurement and statistical processing of history waveforms
History waveforms are measured for the selected measurement item, and statistics are
calculated. Measurement and statistics are taken starting with the oldest waveforms.
