shown in Figure 4-33. This dialog box is similar to the rest of the
waveforms, so the other waveform dialog boxes
will not be
described here.
Creating Sine Waveforms
Use the following procedure to create sine waveforms from the
built-in library. Click on Wave, then sine… and
the dialog box as
shown in Figure 4-33 appears
. You can now start programming
parameters that are available in this box.
Start Point –
Defines the first point where the created wave will
start. Note that if you change the start po
int the left anchor will
automatically adjust itself to the selected start point. The example
shows start point set at point 0.
End Point –
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.
Cycles –
The Cycles parameter defines how many sine cycles will
be created within the specified start and end points. The example
below shows five sine cycles.
Amplitude – 12-bit resolution waveforms have 4096 levels and 16-
bit resolution waveforms have 65,536 levels
. The Amplitude
parameter defines how many of these steps are used for generating
the sine. The example is showing a
sine waveform with maximum
peak-to-peak amplitude for a 12-bit waveform. Any number range
below the maximum and minimum values generates a sine with
reduced dynamic range.
Start Phase – The start phase parameter defines the angle at which
the sine will start. The example shows start phase of 90°.
Power –
The example shows sine cubed. Sine to the power of 1 will
generate a perfect sine. Power range is from 1 through 9.
