Waveform Calcu-
lation Example
Calculate the RMS waveform from the instantaneous waveform
The RMS values of the waveform input on Channel 1 are calculated and dis-
played. This example describes the calculation of waveform data measured for
one cycle over two divisions.

1
Enable the Waveform Calculation function.
Move the cursor to the [Wave Calculation] item, and select
[On] .
2
Specify the waveform calculation range.
Move the cursor to the [Calc Area] item, and select [Whole
Area] .
3
Perform calculation settings.
Move the cursor to the [Equation] column of No. Z1 and
then select [Enter EQN] .
A dialog is displayed for entering a calculation equation.
4
When finished entry, select
[Confirm] .
The entered equation is displayed in the [
Equation
] field.
5
Execute the calculations.
Press the START key to start measurement.
The calculation waveform is displayed after acquiring the input wave-
form.
It is convenient to set con-
stants beforehand on the
[CONST.] (

SQR(MOV(CH1*CH1,200))
The number of samples per cycle (1 division = 100
samples) Here, one cycle is two divisions (200
samples)
After selecting the channel num-
ber, select the
