Performing Waveform Calculations
7
Set the type of the waveform calculation.
Four arithmetic

Performs between channels addition, subtraction, multiplication, and division.
This setting allows you to enter channels, coe󰀩cients, and constants.
(You can also set exponents as constants.)
If division by zero is found, the calculation will result in 1.797693e+308.
Aggregation Adds the measurement data and plot its sum total.
Set the channel, [Reset start time], and [Reset time].
Simple average Adds and average all measurement data from the start of measurement and plots the
results.
Set the channel, [Reset start time], and [Reset time].
Moving average Calculates the average using the specied number of points while moving.
Perform averaging processing using the specied number of points for each sampled
data point and plots the results.
Set the channel, and [Number of points].
Integration Adds values obtained by multiplying measurement data by the sampling period and
plot the sum total.
Set the channel, [Reset start time], and [Reset time].
8
(When [Four arithmetic] is selected)
Specify constants, target channels, and operators.

: Any one operation sign of plus (+), minus (−), multiplication (
∗
), or division(/) or a blank character
If entering a blank character, you cannot enter any further terms in the parentheses

: Any one operation sign of plus (+), minus (−), multiplication (
∗
), division(/), or exponentiation (^)
or a blank character
If entering a blank character, you cannot enter a constant.
Example: To write an expression (A

When you select a calculation sign,
its constants and channels will be
displayed.
When you select a calculation sign,
its constants will be displayed.
Example: [ (100
∗
U1-1) + (50
∗
U1-2) ] + [ 10 ]
You can select a calculation channel as a target channel; however, you cannot select a calculation
channel with a number that is larger than the number of the congured calculation channel.
Example: You can set [W1] through [W4] as the calculation channel for [W5].
