Returns an array of measurement status, margins, margin frequencies, absolute and relative powers corresponding to the margin-frequencies for upper offset segments. The relative powers are relative to the peak power in the carrier.

Namespace: NationalInstruments.RFmx.WlanMX

Assembly: NationalInstruments.RFmx.WlanMX.Fx40 (in NationalInstruments.RFmx.WlanMX.Fx40.dll) Version: 19.1.0.49152 (19.1.0.49152)

Syntax

Visual Basic (Declaration)
Public Function FetchUpperOffsetMarginArray ( _
	selectorString As String, _
	timeout As Double, _
	ByRef measurementStatus As RFmxWlanMXSemUpperOffsetMeasurementStatus(), _
	ByRef margin As Double(), _
	ByRef marginFrequency As Double(), _
	ByRef marginAbsolutePower As Double(), _
	ByRef marginRelativePower As Double() _
) As Integer

C#
public int FetchUpperOffsetMarginArray(
	string selectorString,
	double timeout,
	ref RFmxWlanMXSemUpperOffsetMeasurementStatus[] measurementStatus,
	ref double[] margin,
	ref double[] marginFrequency,
	ref double[] marginAbsolutePower,
	ref double[] marginRelativePower
)

Parameters

selectorString
Type: System.String
Specifies the result name. The result name can either be specified through this input or the resultName parameter. If you do not specify the result name in this parameter, either the result name specified by the resultName parameter or the default result instance is used. Example:
""
""
"result::r1"
You can use the NationalInstruments.RFmx.WlanMX.RFmxWlanMX.BuildResultString method to build the selector string.
timeout
Type: System.Double
Specifies the timeout for fetching the specified measurement. 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. This value is expressed in seconds.
measurementStatus
Type: NationalInstruments.RFmx.WlanMX.RFmxWlanMXSemUpperOffsetMeasurementStatus [] %
Upon return, contains the array of upper offset (positive) segment measurement status, indicating whether the spectrum exceeds the SEM measurement mask limits in the upper offset segments.
margin
Type: System.Double [] %
Upon return, contains the array of margins from the SEM measurement mask for the upper (positive) offset. This value is expressed in dB. Margin is defined as the maximum difference between the spectrum and the mask.
marginFrequency
Type: System.Double [] %
Upon return, contains the array of frequencies corresponding to the margins for the upper (positive) offsets. This value is expressed in Hz.
marginAbsolutePower
Type: System.Double [] %
Upon return, contains the array of absolute powers corresponding to the margins for the upper (positive) offsets. This value is expressed in dBm.
marginRelativePower
Type: System.Double [] %
Upon return, contains the array of relative powers corresponding to the margins for the upper (positive) offsets. The relative powers are relative to the peak power of the carrier channel. This value is expressed in dB.

Return Value

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