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


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 RFmxGSM_WaitforMeasurementComplete function or RFmxGSM_CheckMeasurementStatus function.


Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxGSM_Initialize function.
selectorString char[] Specifies a selector string comprising of the signal name and result name. The result name can either be specified through this input or the resultName 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 resultName parameter or the default result instance is used.
You can use the RFmxGSM_BuildSignalString function to build the selector string.
resultName char[] 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.
