DAPL Signal Generation Commands

DAPL signal generation commands compute repeating or non-repeating 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 swept-frequency "chirp" waveforms for sonic imaging and frequency response testing.

COPYVEC

Expand a list of arbitrary values into a repeating waveform.

PIDRAMP

Generating piece-wise linear trajectories or sequences of stepped output levels
