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.

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: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
