5.1 Generation of Standard Waveform and Numerical Expression Waveform
5.1.3 Parameter setting
The parameters in “Figure 5-1 Waveform Generation Screen” can be set for sine waves, triangle
waves, square waves, noise, and DC.

The size can be calculated by subtracting (lower limit) from (upper limit) of the range specification
(X) on the page. When the size is changed, the upper limit of range specification is changed.
The amplitude is the peak to peak value.
The cycle specifies how many cycles (waves) of the waveform in the range are to be created.
The phase unit is
° (degree).
For the triangle wave, the inclination (symmetry) can be set. The inclination unit is %.
For the square wave, the duty ratio and transition can be set. The duty ratio unit is %. The transition
sets the time for the wave height value to go between 0% and 100% with the ratio to the cycle (%).
If the
[DC Offset]
or
[Amplitude]
setting exceeds the ± full scale value, the waveform is clipped
at the ± full scale value.
When the mouse cursor is moved to the waveform display area on the waveform generation screen,
the shape of mouse cursor changes to or .
Dragging the mouse in the status vertically or horizontally moves the waveform.
[DC Offset] is
changed by vertical operations and [Phase] is changed by horizontal operations.
Dragging the mouse in the status vertically or horizontally extends or compress the waveform.
[Amplitude] is changed by vertical extension/compression and [Period] is changed by vertical
extension/compression.
Using or enables you to intuitively set parameters while looking at the waveform. It is also
possible to roughly make settings in this way and then set a more accurate value by inputting
numerical values.
