Creating Waveforms From the Built-in Library
You can create any waveform from the built-in library using the Wave
command. Clicking on one of the Wave options will open a dialog box.
An example of the Sine waveform dialog box is shown in Figure 5-19.
This dialog box is representative of the rest of the waveforms, so other
waveforms will not be described.
Creating Sine Waveforms
Use the following procedure to create sine waveforms from the built-in
library. Click on Wave, then sine... the dialog box as shown in Figure
5-19 will appear. You can now start programming parameters that are
available in this box.
Start Point Anchor – Defines the first point where the created wave
will start. Note that if you change the start point the left anchor will
automatically adjust itself to the selected start point. The example
shows start point set at point 200.
End Point Anchor – Defines where the created waveform will end.
Note that as you change the end point the right anchor will
automatically adjust itself to the selected end point. The example
shows end point set at point 499.
Max. Peak Deviation – This parameter defines the forward peak
deviation. Note that the forward peak deviation cannot exceed the pre-
defined Deviation parameter as shown on the Toolbar. In case you
need to exceed the pre-defined peak value you must quit this box and
modify the Deviation parameter to provide sufficient range for the
forward peak deviation range.
Min. Peak Deviation – This parameter defines the backwards peak
deviation. Note that the backwards peak deviation cannot exceed the
pre-defined Deviation parameter as shown on the Toolbar. In case
you need to exceed the pre-defined peak value you must quit this box
and modify the Deviation parameter to provide sufficient range for the
backwards peak deviation range.
Cycles – The Cycles parameter defines how many sin
e cycles will be
created within the specified start and end anchor points. The example
below shows thre
e sine cycles.
Start Phase – The start phase parameter defines the angle of which
the sine will start. The example shows 0° start phase.
Power – Sine to the power of 1 will generate a perfect sine. Power
range is from 1 through 9.
