7.4.2 Numerical Calculation Expressions
Calculation Type Description
Average
Obtains the average value of waveform data.
Peak-to-Peak (P-P)
Value
Obtains the value of the difference (peak-to-
peak value) between maximum and mini-
mum values of waveform data.
Maximum Value
Obtains the maximum value of waveform
data.
Time to Maximum
Value (Time to Max)
Calculate the time (s) from the trigger point
to the maximum value.
If the maximum value occurs in two or more
instances, the first instance is treated as the
maximum value.
Minimum Value
Obtains the minimum value of waveform
data.
Time to Minimum
Value (Time to Min)
Calculate the time (s) from the trigger point
to the minimum value.
If the minimum value occurs in two or more
instances, the first instance is treated as
the minimum value.
Standard Deviation
(Std Deviation)
Obtains the standard deviation of the waveform data.
Area
Obtains the area value (V•s) enclosed by the
zero position (point of zero potential) and the
signal waveform.
When calculation of the range specified by the A/
B cursors is selected, the calculated area is con-
strained to the waveform between the cursors.
Integration
Calculate the totalization value of the signal waveforms.
Integral
Calculate the integral of the signal waveforms.

• When Scaling is enabled, calculations are performed after waveform data has
been scaled. Also, the units of parameter values should match the scaling units.
• See "Scaling Function" (p. 98).
