Returns the total absolute and relative powers, peak, absolute, and relative powers, and the frequency at the peak absolute power of the upper offset segment. The relative power is relative to the total aggregated power. Use "offset<n>" or "subblock<n>/offset<n>" as the selector string to read results from this function.

Syntax

int32 __stdcall RFmxNR_SEMFetchUpperOffsetPower(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 *totalAbsolutePower, float64 *totalRelativePower, float64 *peakAbsolutePower, float64 *peakFrequency, float64 *peakRelativePower)

Parameters

NameDirectionTypeDescription
instrumentHandle[in]niRFmxInstrHandle

This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function.

selectorString[in]char

This parameter specifies a Selector String comprising of the signal name, result name, subblock number, carrier number, and offset number. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "" (empty string).
Example:
"subblock0/offset0"
"signal::sig1/subblock0/offset0"
"signal::sig1/result::r1/subblock0/offset0"
"result::r1/subblock0/offset0"
You can use the RFmxNR Build Offset String function to build the selector string.

timeout[in]float64

This parameter 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 function waits until the measurement is complete. The default value is 10.

totalAbsolutePower[out]float64 *

This parameter returns the upper (positive) offset segment power. This value is expressed in dBm.

totalRelativePower[out]float64 *

This parameter returns the power in the upper offset segment relative to total aggregated power. This value is expressed in dB.

peakAbsolutePower[out]float64 *

This parameter returns the peak power in the upper offset segment. This value is expressed in dBm.

peakFrequency[out]float64 *

This parameter returns the frequency at which the peak power occurs in the upper offset segment. This value is expressed in Hz.

peakRelativePower[out]float64 *

This parameter returns the peak power in the upper offset segment relative to total aggregated power. This value is expressed in dB.

Returns

Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred.

To obtain a text description of the status code and additional information about the error condition, call the RFmxNR_GetError function.

The general meaning of the status code is as follows:
