RFmxLteMXAcpResults.FetchOffsetMeasurementArray Method

RFmxLteMXAcpResultsFetchOffsetMeasurementArray Method

Returns an array of absolute and relative powers of the lower and upper offset channels. The relative power is relative to subblock power. The order of the offsets in the result array is universal terrestrial radio access (UTRA) (1, 2, ...m) and evolved universal terrestrial radio access (E-UTRA) (1, ..., n), where m and n are the number of UTRA offsets and the number of EUTRA offsets respectively.
Use "subblock(n)" as the selector string to read results from this method.

Syntax

public int FetchOffsetMeasurementArray(
	string selectorString,
	double timeout,
	ref double[] lowerRelativePower,
	ref double[] upperRelativePower,
	ref double[] lowerAbsolutePower,
	ref double[] upperAbsolutePower
)
Public Function FetchOffsetMeasurementArray ( 
	selectorString As String,
	timeout As Double,
	ByRef lowerRelativePower As Double(),
	ByRef upperRelativePower As Double(),
	ByRef lowerAbsolutePower As Double(),
	ByRef upperAbsolutePower 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.
lowerRelativePower
Type: SystemDouble
Upon return, contains the array of power in lower (negative) offset channel relative to the value returned by the GetTotalAggregatedPower(String, Double) method. For the intra-band non-contiguous type of carrier aggregation, if this offset is not applicable, a NaN is returned. For more information about the applicability of the offset channel, refer to the 3GPP TS 36.521 specification.
upperRelativePower
Type: SystemDouble
Upon return, contains the array of powers in upper (positive) offset channel relative to the value returned by the ACP Results Total Aggregated Pwr method. For the intra-band non-contiguous type of carrier aggregation, if this offset is not applicable, a NaN is returned. For more information about the applicability of the offset channel, refer to the 3GPP TS 36.521 specification.
lowerAbsolutePower
Type: SystemDouble
Upon return, contains the array of lower (negative) offset channel power. For the intra-band non-contiguous type of carrier aggregation, if this offset is not applicable, a NaN is returned. For more information about the applicability of offset channel, refer to 3GPP TS 36.521 specification.
upperAbsolutePower
Type: SystemDouble
Upon return, contains the array of upper (positive) offset channel powers. For the intra-band non-contiguous type of carrier aggregation, if this offset is not applicable, a NaN is returned. For more information about the applicability of offset channel, refer 3GPP TS 36.521 specification.

Return Value

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