Generating
Waveforms Using
Equation Editor
A more general purpose way to create waveforms using
ArbConnection is to use Equation Editor. Equation Editor let you
write equations for the desired waveform and lets ArbConnection
calculate the values and display them on the graph. Equation Editor
detects syntax errors and can auto-scale your waveforms so that no
dynamic range is lost.
When you invoke Equation Editor, the dialog box shown in Figure 4-
36 appears. The following paragraphs describe how to use the
features of Equation Editor..
Figure 4-36, Equation Editor Dialog Box
There are four sub-group parameters in the equation editor plus
control buttons and the equation field. These parts are described
below.
Anchor
The anchors define start and end point at which the equation will be
generated. By default the anchors are placed at the start and the
end of the horizontal (time) scale however, the equation can be
limited to a specific time scale by moving the anchor points from
their default locations.
Start
– 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.
End
– 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.
Waveform Amplitude
The vertical axis of the Wave Composer represents 16-bits of
vertical resolution. That means that the equation is computed,
resolved and generated with 1/65,536 increments and accuracy.
The Waveform Amplitude fields in the Equation Editor are used in
two cases: 1) when the “amp” parameter is used in the equation or
2 if the Level Adjuster is set to Auto. Information on these two
