int32 __stdcall RFmxLTE_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 RFmxLTE_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.

| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function. |
| selectorString | char[] | Specifies a selector string) comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxLTE_BuildSignalString) function to build the selector string. |

| 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 RFmxLTE_GetError) function. The general meaning of the status code is as follows: |

int32 __stdcall RFmxLTE_AnalyzeIQ1Waveform (niRFmxInstrHandle instrumentHandle, char selectorString[], char resultName[], float64 x0, float64 dx, NIComplexSingle IQ[], int32 arraySize, int32 reset, int64 reserved);
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. Use this function only if the is function only if the is function only if the RFMXINSTR_ATTR_RECOMMENDED_ACQUISITION_TYPE) attribute value is either tribute value is either RFMXINSTR_VAL_RECOMMENDED_ACQUISITION_TYPE_IQ or RFMXINSTR_VAL_RECOMMENDED_ACQUISITION_TYPE_IQ_OR_SPECTRAL.
When using the Analysis-Only mode in RFmxLTE, the RFmx 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.
