HELP
An object that outputs a Waveform.

USE
Use Function Generator to generate a Waveform
of your own specifications.

LOCATION
Device ==> Virtual Source ==>
 Function Generator

OBJECT MENU
* Error on Aliasing - Evaluates whether Num
Points divided by Time Span (same frequency)
is less than twice the specified frequency.
If it is, an error is returned.  The purpose
of this evaluation is to determine whether
the points being generated provide an
accurate representation of the function being
generated.  An unchecked checkbox generates a
literal presentation of points.  Default is
on (checked).

OPEN VIEW PARAMETERS
All of these parameters may be set from the
open view or added as data inputs.

* Function - The shape of the waveform (Sine,
Square, Triangle, and so forth).  Default is
Cosine.

* Frequency - The frequency of the waveform
in Hertz.  This parameter is ignored if the
Function is set to DcOnly.  Default is 1000
Hertz.

* Amplitude - The absolute value of the
maximum and minimum values in linear units
before any dcOffset is added.  Default is 1.

* dcOffset - The offset of the waveform (the
amount it is shifted up or down).  Default is
0.

* Phase Units - Degrees (Deg), radians (Rad),
or gradians (Grad).  Phase Units overrides
the current Trig Mode for the phase value.
Default is Deg.

* Phase - The shift of the waveform by a
portion of a period.  The waveform is shifted
toward negative time for positive values of
phase.  Phase is ignored when Function is set
to DcOnly.  Default is 0.

* Time Span - The duration of the waveform
(in seconds).  Default is 20m seconds and is
set in Waveform Defaults.

* Num Points - The number of points in the
waveform.  The time between points in the
waveform is Time Span/Num Points.  Num Points
must be positive.  Default is 256 and is set
in Waveform Defaults.

NOTES
There are the same number of points as
sampling intervals.  Each point is at the
beginning of the sampling interval.
