Glossary Item Box

Gets or sets which subcarrier to analyze (meaningful only if looking at a single subcarrier).

Syntax

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

Property Value

The default value is 1. When the FFT length is 64, the maximum value is 28 and the minimum is -28. When the FFT length is 128, the maximum value is 58 and the minimum is -58. When the FFT length is 256, the maximum value is 122 and the minimum is -122. When the FFT length is 512, the maximum value is 250 and the minimum is -250.

Remarks

This property is used only if SubcarrierSelection is set to SubcarrierSelection.Single. A value of 0 is invalid, because the DC subcarrier is not used in IEEE 802.11n or IEEE 802.11ac modulation. In addition, if the FFT length greater than 64, values of 1 and -1 are not valid. Finally, if the FFT length is 512, values between -129 and -127, between -5 and 5, and between 127 and 129 are not valid.

Requirements

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