Fetches the 70/N us windowed power trace in dBm/MHz for Downlink, while an empty trace is returned for Uplink.
Use "carrier<k>" or "subblock<n>/carrier<k>" as the selector string to read this result.

Syntax

int32 __stdcall RFmxNR_PvtFetchWindowedSignalPowerTrace(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 *x0, float64 *dx, float32 windowedSignalPower[], int32 arraySize, int32 *actualArraySize)

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, and carrier 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 "subblock0/carrier0".
Example:
"subblock0/carrier0"
"signal::sig1/subblock0/carrier0"
"result::r1/subblock0/carrier0"
"signal::sig1/result::r1/subblock0/carrier0"
You can use the RFmxNR Build Carrier String function to build the selector string.

timeout[in]float64

This parameter specifies the timeout for which the function waits for the measurement to complete. This value is expressed in seconds. A value of -1 specifies that the function waits until the measurement is complete.

x0[out]float64 *

This parameter returns start time of the signal. This value is expressed in seconds.

dx[out]float64 *

This parameter returns the time bin spacing. This value is expressed in seconds.

windowedSignalPower[out]float32

This parameter returns the 70/N us windowed power trace in dBm/MHz for Downlink, while an empty trace is returned for Uplink.

arraySize[in]int32

Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter.

actualArraySize[out]int32 *

Returns the actual size of the array, if you pass NULL to all output array parameters, and set the arraySize parameter to 0.

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:
