Generates a uniformly distributed pseudorandom pattern whose values are in the range [–a:a], where a is the absolute value of amplitude.

Inputs/Outputs

  • cbool.png reset signal —

    reset signal, if TRUE, resets the seed to the seed control value and the time stamp to zero. The default is FALSE.

  • cdbl.png amplitude —

    amplitude is the maximum absolute value that signal out can have. The default is 1.0.

  • ci32.png seed —

    seed, when greater than 0, causes reseeding of the noise sample generator. The default is –1.

    LabVIEW maintains the internal seed state independently for each instance of this reentrant VI. For a specific instance of this VI, if seed is less than or equal to 0, LabVIEW does not reseed the noise generator, and the noise generator resumes producing noise samples as a continuation of the previous noise sequence.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • cnclst.png sampling info —

    sampling info contains sampling information.

  • cdbl.png Fs —

    Fs is the sampling rate in samples per second. The default is 1000.

  • cdbl.png #s —

    #s is the number of samples in the waveform. The default is 1000.

  • imsdt.png signal out —

    signal out is the generated waveform.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
