3.9 Operation Between Waveforms
3.9 Operation Between Waveforms
This section explains how to create a waveform by superposing noise over a sine wave, as a
sample of operation between waveforms.
Step 1: Click the button at the left top of the screen.
A sine wave is selected in the initial status.
Change the numerical value to the right of
[Amplitude]
from
[2.0]
to
[1.5]
to
reduce the amplitude a little bit.
Click the
All Page OK
button to return to the waveform display screen.
Step 2: Click the button at the top left of the screen. The same result can be obtained
when
[Tools] - [Operate]
is selected.
The screen titled
[YOKOGAWA ARB Edit - Operate]
appears.
Step 3: Click the
Created Waveform
button in the middle of the inter-waveform operation
screen.
The screen titled
[YOKOGAWA ARB Edit – Waveform Create]
appears as when
the button is clicked.
Step 4: Click the button to the right of
[Function]
and click
[Noise]
from the displayed
list.
Change the numerical value to the right of
[Amplitude]
from
[2.0]
to
[0.4]
.
Click the
Page OK
button to return to the inter-waveform operation screen.
Step 5: When the
=
button is clicked, the waveform created as a result of addition of the sine
wave and noise is displayed in the waveform display area to the right of the screen.
Step 6: Click the
OK
button to return to the waveform display screen.
The waveform superposing noise over the sine wave is now created.
Explanation 1: Besides the addition shown in this example, subtraction, multiplication, and division
are possible.
Explanation 2: The operation can be executed targeting a part of the waveform by selecting the part
on the waveform display screen with markers A and B in advance.
Explanation 3: In this example, the waveform created on the waveform generation screen is used for
operation.
The data on the “clipboard” can be used by clicking the
Clip Board
button in step 3.
Clipboard: See “3.4 Copying and Pasting a Waveform”.
Explanation 4: It is convenient to set the vertical axis to ±1 of the custom as in the example in “3.5
Numerical Expression Waveform” when executing multiplication.
Under this setting, the result of multiplying full scale values will also be a full scale
value.
