Glossary Item Box

Gets or sets the maximum FFT length for spectrum calculations.

Syntax

Visual Basic (Declaration) 
Public Overridable Property SpectrumFftLengthMaximum As Integer
C# 
public virtual int SpectrumFftLengthMaximum {get; set;}
C++/CLI 
public:
virtual property int SpectrumFftLengthMaximum {
   int get();
   void set (    int value);
}

Property Value

The default value is 16384. The minimum value is 64.

Remarks

This value is used when calculating the Phase Noise Spectrum, and also for the FM Meas Spectrum, FM Ref Spectrum, and FM Error Spectrum results. The time length for FFTs for computing these traces is the smaller of SpectrumFftLength, or the power of two greater than or equal to the number of samples in the acquisition length. If the FFT length is smaller than the acquisition length, multiple FFTs are used and averaged together to produce the spectrum results.

Requirements

Target Platforms: Windows 11 Professional or Enterprise; Windows 10 Professional, Enterprise, or Education (64-bit)

Minimum Software Version Requirement: Keysight PathWave 89600 VSA Ver 20.00
