ccIndex
ComponentCarrier for which to compute cross-correlated EVM

Glossary Item Box

Configured the measurement for cross-correlated EVM on the given ComponentCarrier.

Syntax

Visual Basic (Declaration) 
Public Overridable Sub ConfigureCrossCorrelatedEvm( _
   ByVal ccIndex As Integer _
)
C# 
public virtual void ConfigureCrossCorrelatedEvm( 
   int ccIndex
)
C++/CLI 
public:
virtual void ConfigureCrossCorrelatedEvm( 
   int ccIndex
)

Parameters

ccIndex
ComponentCarrier for which to compute cross-correlated EVM

Exceptions

ExceptionDescription
System.ArgumentOutOfRangeExceptionThrown if ccIndex is invalid.
System.InvalidOperationExceptionThrown if input channels are less than 2.
System.InvalidOperationExceptionThrown if the signals are not captured at the same moment in time (sequential acquisition is not supported).

Remarks

Cross-Correlated EVM is a measurement where the same signal is measured through two different input channels to reduce the EVM contributions from the input channels themselves.

This method removes all but the specified ccIndex, so that it becomes CC0, duplicates it to CC1, and configures the component carriers such that measurement channel CC0 <- Ch1 and CC1 <- Ch2.

The ccEVM result will be in the Cross Corr EVM Summary trace.

Requirements

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

Minimum Software Version Requirement: Keysight 89600 VSA Ver 30.00
