Glossary Item Box

Gets or sets a value indicating whether EVM values are normalized by the reference power level.

Syntax

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

Property Value

The default value is true.

Remarks

If true, EVM calculations are normalized by the power of the reference. In this case, each EVM value reported on the Error Summary trace and on the OFDM Burst Info trace is separately normalized by the power of the reference for the subcarriers included in the EVM value.

If false, EVM calculations are normalized by the nominal preamble level after adjusting for preamble boosting.

These two methods produce nearly identical answers when they are applied to non-boosted subcarriers. If you assume that the constellation points are all equally likely, the two EVM methods should average to the same value if there is no boosting.

Requirements

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