Name 

Description 

 

Active 

Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method. 

 

Amplt 

Stores the amplitude of the spectrum. 

 

Bands 

Holds the parameters for the frequency bands.  

 

BandWidth 

Returns the bandwidth of the spectrum in [Hz]. 

 

Complex 

Set this property to true, to request computation using complex numbers.  

 

Continuous 

If True, the component will pass on the udpate request to the connected component. 

 

Dt 

Returns the distance in seconds between two consecutive samples of the signal on which the frequency spectrum is based. 

 

FloatPrecision 

may not have default to allow switching of default precision 

 

FloatPrecisionLock 

Set this property to true to lock changes to FloatPrecision property.  

 

Harmonics 

Defines number of harmonics to be used when calculating statistical parameters from the amplitude spectrum. 

 

HzRes 

Returns the frequency resolution in Hz. 

 

Integration 

Define the integration/differenation of the frequency spectrum.  

 

IsDouble 

may not have default to allow switching of default precision 

 

Length 

Defines the length of the spectrum.  

 

Logarithmic 

Set it to True, to obtain the logarithm of the spectrum in dB.  

 

LogBase 

Defines the base of the logarithmic spectrum.  

 

LogScale 

Defines the scaling of the logarithmic spectrum.  

 

LogSpan 

Defines the span of the logarithmic spectrum in dB.  

 

LogType 

Specify how to apply the logarithm to the spectrum.  

 

MainlobeWidth 

Defines the width of the main lobe. Each frequency component in the frequency spectrum should theoretically be infinitely thin. 

 

OnAfterUpdate 

The event is triggered after the call to the Update method. 

 

OnBandsUpdate 

If assigned, this event will be called instead of a call to Bands.Update method.  

 

OnBeforeUpdate 

The event is triggered just before the call to the Update method. 

 

OnDisplayUpdate 

The event is triggered after the OnAfterUpdate event. Use this event to update any associated charts or graphs or result tables. 

 

OnGetInput 

If the Input property is not assigned, the component will call OnGetInput. 

 

OnNotifyUpdate 

The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method. 

 

OnParameterUpdate 

The event is triggered when ParamUpdate method is called. The ParamUpdate method is usually called by component editors when a value was changed by the user and the editor was "Live".  

 

OnPeaksUpdate 

If assigned, this event will be called instead of a call to Peaks.Update method.  

 

Peaks 

Pointer to the component that manages peak analysis.  

 

Phase 

Stores the phase of the spectrum.  

 

PhaseMode 

This property determines how to handle the phase of the frequency spectrum. 

 

PhaseRange 

Specify the range of the phase spectrum. 

 

PhaseUnits 

Defines the units of phase. (radian, degrees). 

 

Report 

Holds the parameters needed to generate a spectrum analysis report. Requires that the descriptor property is properly filled up.  

 

Rotation 

Before the frequency analysis, the signal can be circularly rotated by a specified number of samples. Rotation defines the number of samples.  

 

SamplingFrequency 

Defines the sampling frequency of the signal on which the frequency spectrum is based. 

 

SamplingTime 

Defines the length of the signal on which the frequency spectrum is based in seconds. 

 

ScaleFactor 

Frequency spectrum will be scaled by a scale factor.  

 

SpectrumType 

Specifies the spectrum type to be computed.  

 

ZeroPadding 

Defines the level of zero padding of the source signal.
