Palette Object Description
SV Multitone Gain and Phase Use this VI to measure the gain and phase versus frequency. Wire data to scaled signal [EU] to determine the polymorphic instance to use or manually select the instance.
SV Multitone SINAD and THD+N Performs a signal in noise and distortion (SINAD) analysis and analyzes total harmonic distortion plus noise (THD + N), including measuring the fundamental tones, and returns the and SINAD and THD + N in the desired units. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance. The following formula calculates SINAD: SINAD = sqrt( F ² + N ² + H ² ) / sqrt( H ² + N ² ) where F is the fundamental tone RMS level, N is the noise RMS level, and H is the harmonic RMS level.
SV Multitone THD IMD SNR Performs total harmonic distortion (THD), intermodulation distortion (IMD), and signal-to-noise ratio (SNR) measurements, including measuring the fundamental tones, harmonic components, intermodulation components, and residual noise. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.
SVFA Extract Tone Information Identifies a sinusoidal component in a scaled signal. A sinusoidal component is a peak in the magnitude of the complex spectrum. This VI does not maintain state, you can use this VI in a loop to process an array of channels.
SVL AC & DC Level Computes the AC level and DC level of a signal. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.
SVT Intermodulation Distortion Computes the total intermodulation distortion and the intermodulation components of scaled signal [EU] and IMD standard .
SVT Phase Linearity Computes the multitone phase of each tone in a multitone signal, the average group delay, and the max deviation of the phase from a straight line. Use a square wave or construct the input signal with component tones evenly spaced in frequency and with zero relative phase between the component tones.
