RFmxNR_AnalyzeIQ1WaveformSplit
int32 __stdcall RFmxNR_AnalyzeIQ1WaveformSplit (niRFmxInstrHandle instrumentHandle, char selectorString[], char resultName[], float64 x0, float64 dx, float32 I[], float32 Q[], int32 arraySize, int32 reset, int64 reserved);
Purpose
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
RFMXINSTR_ATTR_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.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxNR_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 RFmxNR_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" |
| x0 | float64 | Specifies the start time of the input Y array. This value is expressed in seconds. |
| dx | float64 | Specifies the frequency interval between data points in the spectrum. |
| IQ | NIComplexSingle[] | Specifies the array of the real part of complex-valued time domain data. This array corresponds to the in-phase (I) data. |
| IQ | NIComplexSingle[] | Specifies the array of the imaginary part of complex-valued time domain data. This array corresponds to the quadrature-phase (Q) data. |
| arraySize | int32 | Specifies the size of the array. |
| reset | int32 | Resets measurement averaging. If you enable averaging, set this parameter to TRUE for first record and FALSE for subsequent records.
|
| reserved | int64 | Reserved for future use. Any value passed to this parameter will be ignored. |
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 RFmxNR_GetError function. The general meaning of the status code is as follows:
