RFmxLteMXModAccResultsFetchInBandEmissionTrace Method

Returns the in-band emission (IBE) and limit traces. In-band emission is the interference falling into non allocated resource blocks. The IBE for various spectral regions (general, carrier leakage, and I/Q image) are evaluated according to section 6.5.2.3.5 of the 3GPP 36.521 specification and concatenated to form a composite trace. The limit trace is derived from the limits in the section 6.5.2.3.5 of the 3GPP 36.521 specification.
The method result is valid only when you set the SetLinkDirection(String, RFmxLteMXLinkDirection) method to Uplink.
Use "carrier(k)" or "subblock(n)/carrier(k)" 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 FetchInBandEmissionTrace(
	string selectorString,
	double timeout,
	ref AnalogWaveform<float> inBandEmission,
	ref AnalogWaveform<float> inBandEmissionMask
)

Public Function FetchInBandEmissionTrace ( 
	selectorString As String,
	timeout As Double,
	ByRef inBandEmission As AnalogWaveform(Of Single),
	ByRef inBandEmissionMask As AnalogWaveform(Of Single)
) As Integer

Parameters

selectorString: Type: SystemString
Specifies a selector string comprising of the result name, subblock number, and carrier number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/carrier0"
"result::r1/subblock0/carrier0"
You can use the BuildCarrierString(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.
inBandEmission: Type: NationalInstrumentsAnalogWaveformSingle
Upon return, contains the in-band emission margin.
inBandEmissionMask: Type: NationalInstrumentsAnalogWaveformSingle
Upon return, contains the in-band emission mask.

Return Value

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