RFmxBT_Initiate
int32 __stdcall RFmxBT_Initiate (niRFmxInstrHandle instrumentHandle, char selectorString[], char resultName[]);
Purpose
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
RFmxBT_WaitforMeasurementComplete function or
RFmxBT_CheckMeasurementStatus function.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxBT_Initialize function. |
| selectorString | char[] | Specifies 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. Example: "" "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxBT_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. Example: "" "result::r1" "r1" |
Return Value
| Name | Type | Description | ||||||||
| status | int32 | 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 RFmxBT_GetError function. The general meaning of the status code is as follows:
