Summary

Supplied as a parameter class in the OnBinMaskOpportunity event.

Description

This object, supplied as a parameter in the OnBinMaskOpportunity event, contains the results of the noise statistic calculations. Read-only properties include Harmonic[], Fundamental, SFDR, SFDRBin, SNR, THD, SINAD, ENOB, IntNoiseFloor, and AvgNoise. Inherited read-only properties include: HarmonicBin[], NumHarmonics, FundBin, and FundBinFractional. See each property for a description.

Properties

Public

• Harmonic - Returns the amplitude of the “I+1”th harmonic of the fundamental (dBFS).
• DataMean - Returns the arithmetic mean of the incoming data.
• DCDataOffset - Returns the offset of the incoming data.
• AvgNoise - Returns the average noise in the spectrum (dBFS).
• IntNoiseFloor - Returns the amplitude of the Integrated Noise Floor is equivalent to Fundamental – SNR, dBFS.
• ENOB - Returns the Effective Number of Bits (ENOB).
• SINAD - Returns the Signal-to-Noise-and-Distortion ratio.
• THD - Returns the Total Harmonic Distortion.
• SNR - Returns the Signal-to-Noise ratio.
• SFDRBin - Returns the bin where SFDR was located.
• SFDR - Returns the Spurious Free Dynamic Range.
• Fundamental - Returns the amplitude of the fundamental frequency (dBFS).

Properties

Public

• NumHarmonics - Returns the size of the array of located harmonics. (To set the value of harmonics to be located, use property SLNoiseStats.NumHarmonics.)
• HarmonicBin - Returns the bin location in the FFT ouput of the “I+1”th harmonic of the fundamental frequency.
• FundBinFractional - Returns the (floating point) bin location in the FFT output of the fundamental frequency.
• FundBin - Returns the (unsigned integer) bin location in the FFT output of the fundamental frequency.
