DAPL Signal Generation Commands
DAPL signal generation commands compute repeating or nonrepeating signal sequences.
Most of the time, these signals are used as output waveforms, but the sequences are sometimes used internally, for example, to apply amplitude modulation to another waveform.
COSINEWAVE
 Compute values for a repeating or modulated cosine wave.
SINEWAVE
 Compute values for a repeating or modulated sine wave.
SQUAREWAVE
 Compute values for a repeating or modulated square wave.
TRIANGLE
 Compute values for a repeating or modulated triangle wave.
SAWTOOTH
 Compute values for a repeating or modulated sawtooth wave.
RANDOM
 Generate an uncorrelated (white) uniform noise sequence.
Some additional commands can be used to construct more complex signal forms.
CHIRP
 Generate sweptfrequency "chirp" waveforms for sonic imaging
and frequency response testing.
COPYVEC
 Expand a list of arbitrary values into a repeating waveform.
PIDRAMP
 Generating piecewise linear trajectories or sequences of stepped
output levels
