RFmxLteMXModAccResultsFetchSubblockInBandEmissionTrace Method

Returns the in-band emission trace and the limit trace within the subblock aggregated bandwidth. The in-band emissions are a measure of the interference in the non-allocated resources blocks. The in-band emissions for various regions, such as general, carrier leakage, and I/Q image, are evaluated according to the method defined in the 3GPP 36.521 specification, and concatenated to form a composite trace. Limit trace is derived from the limits defined in section 6.5.2A.3 of the 3GPP TS 36.521 specification.
The method result is valid only when you set the SetLinkDirection(String, RFmxLteMXLinkDirection) method to Uplink and the SetTransmitterArchitecture(String, RFmxLteMXTransmitterArchitecture) method to LOPerSubblock.
Use "subblock(n)" as the selector string to read results from this method.

Namespace: NationalInstruments.RFmx.LteMX
Assembly: NationalInstruments.RFmx.LteMX.Fx40 (in NationalInstruments.RFmx.LteMX.Fx40.dll) Version: 24.5.0.49283 (24.5.0.49283)

Syntax

public int FetchSubblockInBandEmissionTrace(
	string selectorString,
	double timeout,
	ref double[] subblockInBandEmission,
	ref double[] subblockInBandEmissionMask,
	ref double[] subblockInBandEmissionRBIndices
)

Public Function FetchSubblockInBandEmissionTrace ( 
	selectorString As String,
	timeout As Double,
	ByRef subblockInBandEmission As Double(),
	ByRef subblockInBandEmissionMask As Double(),
	ByRef subblockInBandEmissionRBIndices As Double()
) As Integer

Parameters

selectorString: Type: SystemString
Specifies a selector string comprising of the result name, and subblock number. If you do not specify the result name, the default result instance is used. Example:
"subblock0"
"result::r1/subblock0"
You can use the BuildSubblockString(String, Int32) method to build the selector string.
timeout: Type: SystemDouble
Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete.
subblockInBandEmission: Type: SystemDouble
Upon return, contains the array of the subblock in-band emission measurement trace.
subblockInBandEmissionMask: Type: SystemDouble
Upon return, contains the array of the subblock in-band emission mask trace.
subblockInBandEmissionRBIndices: Type: SystemDouble
Upon return, contains the array of the resource block indices for the subblock in-band emission trace. It can have non integer values depending upon the spacing between carriers.

Return Value

Type: Int32
Returns the status code of this method. The status code either indicates success or describes a warning condition.
