Returns an array of total absolute and relative powers, peak, absolute, and relative powers, and frequencies at peak absolute powers of lower offset segments. The relative power is relative to total aggregated power.
Use "subblock(n)" as the selector string to read results from this method.

Syntax

public int FetchLowerOffsetPowerArray(string selectorString, double timeout, ref double[] absoluteIntegratedPower, ref double[] relativeIntegratedPower, ref double[] absolutePeakPower, ref double[] peakFrequency, ref double[] relativePeakPower)

Parameters

NameTypeDescription
selectorStringstring

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, int) method to build the selector string.

timeoutdouble

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.

absoluteIntegratedPowerref double[]

Upon return, contains the array of lower (negative) offset segment powers. For the intra-band non-contiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.

relativeIntegratedPowerref double[]

Upon return, contains the array of powers in the lower (negative) offset segment relative to the value returned by the GetTotalAggregatedPower(string, out double) method. For the intra-band non-contiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.

absolutePeakPowerref double[]

Upon return, contains the array of peak powers in the lower (negative) offset segment. For the intra-band non-contiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.

peakFrequencyref double[]

Upon return, contains the array of frequency at which the peak power occurs in the upper (positive) offset segment. For the intra-band non-contiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.

relativePeakPowerref double[]

Upon return, contains the array of peak power in the upper (positive) offset segment relative to the value returned by the SEM Results Total Aggregated Pwr method. For the intra-band non-contiguous type of carrier aggregation, the offset segment may be truncated or discarded based on offset overlap rules as defined in the 3GPP TS 36.521 specification. If the offset segment is truncated the measurement is performed on the updated offset segment. If the offset segment is discarded, a NaN is returned.

Returns

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