Initiates all enabled measurements. Call this function after configuring the signal and measurement. This function asynchronously launches measurements in the background and immediately returns to the caller program. You can fetch measurement results using the Fetch functions or result attributes in the attribute node. To get the status of measurements, use the RFmxNR_WaitForMeasurementComplete function or RFmxNR_CheckMeasurementStatus function.

Syntax

int32 __stdcall RFmxNR_Initiate(niRFmxInstrHandle instrumentHandle, char selectorString[], char resultName[])

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 the signal name and result name. The result name can either be specified through this input or the Result Name parameter. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name in this parameter, either the result name specified by the Result Name parameter or the default result instance is used. The default value is "" (empty string).
Example:
""
"signal::sig1"
"result::r1"
"signal::sig1/result::r1"
You can use the RFmxNR_BuildSignalString function to build the Selector String.

resultName[in]char

This parameter specifies the name to be associated with measurement results. Provide a unique name, such as "r1" to enable fetching of multiple measurement results and traces. This input accepts the result name with or without the "result::" prefix. The default value is "" (empty string) which refers to default result instance.
Example:
"result::r1"
"r1"

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:
