Waveform Generation VIs

Owning Palette: Analog Waveform VIs and Functions, Signal Processing VIs

Use the Waveform Generation VIs to generate different types of single and multitone signals, function generator signals, and noise signals. Example

The VIs on this palette can return general LabVIEW error codes or specific waveform error codes.

Palette Object	Description
Basic Function Generator	Creates an output waveform based on signal type.
Basic Multitone with Amplitudes	Generates a waveform that is the sum of integer cycle sine tones.
Basic Multitone	Generates a waveform that is the sum of integer cycle sine tones.
Bernoulli Noise Waveform	Generates a pseudorandom pattern of ones and zeroes. Each element of signal out is computed by flipping a coin weighted by one probability.
Binomial Noise Waveform	Generates a binomially-distributed pseudorandom pattern whose values are the number of occurrences of an event given the probability of that event occurring and the number of trials.
Formula Waveform	Creates an output waveform using a formula string to specify the time function to be used.
Gamma Noise Waveform	Generates a pseudorandom pattern of values which are the waiting times to the order number event of a unit mean Poisson process.
Gaussian White Noise Waveform	Generates a Gaussian distributed pseudorandom pattern whose statistical profile is (0,s), where s is the absolute value of the specified standard deviation.
Inverse f Noise Waveform	Generates a continuous noise waveform with a power spectral density that is inversely proportional to frequency over a specified frequency range.
MLS Sequence Waveform	Generates a maximum length sequence of ones and zeroes using a modulo-2 primitive polynomial of order polynomial order.
Multitone Generator	Generates a waveform that is the sum of integer cycle sine tones.
Periodic Random Noise Waveform	Generates a waveform containing periodic random noise (PRN).
Poisson Noise Waveform	Generates a pseudorandom sequence of values which are the number of discrete events occurring in the interval specified by mean of a unit rate Poisson process.
Sawtooth Waveform	Generates a waveform containing a sawtooth wave.
Simulate Arbitrary Signal	Simulates a signal that you define.
Simulate Signal	Simulates a sine wave, square wave, triangle wave, sawtooth wave, or noise signal.
Sine Waveform	Generates a waveform containing a sine wave.
Square Waveform	Generates a waveform containing a square wave.
Tones and Noise Waveform	Generates a waveform composed of a sum of sine tones, noise, and DC offset.
Triangle Waveform	Generates a waveform containing a triangle wave.
Uniform White Noise Waveform	Generates a uniformly distributed pseudorandom pattern whose values are in the range [–a:a], where a is the absolute value of amplitude.
