RFmxLteMXAcpResults.FetchOffsetMeasurement Method

RFmxLteMXAcpResultsFetchOffsetMeasurement Method

Returns the absolute and relative power of the lower and upper offset channel. The relative power is relative to subblock power.
Use "offset(n)" or "subblock(n)/offset(n)" as the selector string to read results from this method.
Refer to the LTE Uplink Adjacent Channel Power and LTE Downlink Adjacent Channel Power topics for more information.

Namespace:  NationalInstruments.RFmx.LteMX

Syntax

public int FetchOffsetMeasurement(
	string selectorString,
	double timeout,
	out double lowerRelativePower,
	out double upperRelativePower,
	out double lowerAbsolutePower,
	out double upperAbsolutePower
)
Public Function FetchOffsetMeasurement ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef lowerRelativePower As Double,
	<OutAttribute> ByRef upperRelativePower As Double,
	<OutAttribute> ByRef lowerAbsolutePower As Double,
	<OutAttribute> ByRef upperAbsolutePower As Double
) As Integer

Parameters

selectorString
Type: SystemString
Specifies a selector string comprising of the result name, subblock number, and offset number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/offset0"
"result::r1/subblock0/offset0"
You can use the BuildOffsetString(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 power in lower (negative) offset channel relative to 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 power 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 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 an offset channel, refer to the 3GPP TS 36.521 specification.
upperAbsolutePower
Type: SystemDouble
Upon return, contains the upper (positive) 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 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.
