Owning Palette: Spectral Analysis PtByPt VIs
Requires: Full Development System
Computes the single-sided, scaled, auto power spectrum of a time-domain signal.
This VI is similar to the Auto Power Spectrum VI.
 | Note By default, reentrant execution is enabled in all Point By Point VIs. |

initialize, when TRUE, initializes the internal state of the VI. |
 |
signal specifies the input time-domain signal, usually in volts. |
 |
sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than 0. |
|
dt is the sample period of the time-domain signal, usually in seconds. Set dt to 1/fs, where fs is the sampling frequency of the time-domain signal. The default is 1. |
 |
Power Spectrum returns the single-sided power spectrum. If the input Signal is in volts (V), Power Spectrum has units of volts-rms squared (Vrms2). If the input Signal is not in volts, Power Spectrum has units of the input signal unit-rms squared. |
 |
df is the frequency interval of the power spectrum in hertz, if dt is in seconds. |
 |
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster. |
