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

Stops acquisition and measurements associated with signal instance that you specify in the selectorString parameter, which were previously initiated by the RFmxNR_Initiate) function or measurement read functions. Calling this function is optional, unless you want to stop a measurement before it is complete. This function executes even if there is an incoming error.

Performs the enabled measurements on the I/Q complex waveform that you specify in IQ parameter. Call this function after you configure the signal and measurement attributes. You can fetch measurement results using the Fetch functions or result attributes in the attribute node. Use this function only if the Recommended Acquisition Type attribute value is either IQ or IQorSpectral. When using the Analysis-Only mode in RFmxNR, the RFmx driver ignores the RFmx hardware settings such as reference level and attenuation. The only RF hardware settings that are not ignored are the center frequency and trigger type, since it is needed for spectral measurement traces as well as some measurements such as ModAcc, ACP, and SEM.
