RFmxLteMXModAccResults.FetchInBandEmissionMargin Method

RFmxLteMXModAccResultsFetchInBandEmissionMargin Method

Returns the in-band emission margin on non allocated resource blocks (RBs) in the uplink signal. This value is expressed in dB.
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 FetchInBandEmissionMargin(
	string selectorString,
	double timeout,
	out double inBandEmissionMargin
)
Public Function FetchInBandEmissionMargin ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef inBandEmissionMargin As Double
) 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.
inBandEmissionMargin
Type: SystemDouble
Upon return, contains the in-band emission margin. The margin is the least difference between the in-band emission measurement trace and limit trace. The limit is defined in section 6.5.2.3.5 of the 3GPP TS 36.521 specification. The in-band emissions are a measure of the interference falling into the non-allocated resources blocks.

Return Value

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