Returns the recovered physical uplink shared channel (PUSCH) constellation points. The constellation points of different slots in the RFMXLTE_ATTR_MODACC_MEASUREMENT_LENGTH are concatenated.
Syntax
int32 __stdcall RFmxLTE_ModAccFetchPUSCHConstellationTraceSplit(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float32 dataConstellationI[], float32 dataConstellationQ[], int32 dataConstellationArraySize, int32 *dataConstellationActualArraySize, float32 dmrsConstellationI[], float32 dmrsConstellationQ[], int32 dmrsConstellationArraySize, int32 *dmrsConstellationActualArraySize)
Remarks
Use "carrier<k>" or "subblock<n>/carrier<k>" as the selector string to read results from this function.
Parameters
Name | Direction | Type | Description |
---|---|---|---|
instrumentHandle | [in] | niRFmxInstrHandle | This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function. |
selectorString | [in] | char | This parameter specifies a Selector String comprising of the signal name, result name, subblock number, and carrier number. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "subblock0/carrier0". |
timeout | [in] | float64 | This parameter specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the function waits until the measurement is complete. The default value is 10. |
dataConstellationI | [out] | float32 | This parameter Returns the real part of data constellation trace. |
dataConstellationQ | [out] | float32 | This parameter Returns the imaginary part of data constellation trace. |
dataConstellationArraySize | [in] | int32 | This parameter returns the demodulation reference signal (DMRS) constellation trace. |
dataConstellationActualArraySize | [out] | int32 * | Returns the actual size of dataConstellation array, if you pass NULL to all output array parameters, and set the dataConstellationArraySize parameter to 0. |
dmrsConstellationI | [out] | float32 | This parameter Returns the real part of demodulation reference signal (DMRS) constellation trace. |
dmrsConstellationQ | [out] | float32 | This parameter Returns the imaginary part of demodulation reference signal (DMRS) constellation trace. |
dmrsConstellationArraySize | [in] | int32 | Specifies the size of the DMRSConstellation array. Set the DMRSConstellationArraySize parameter to 0 to get the size of the DMRSConstellation array in the DMRSConstellationActualArraySize parameter. |
dmrsConstellationActualArraySize | [out] | int32 * | Returns the actual size of DMRSConstellation array, if you pass NULL to all output array parameters, and set the DMRSConstellationArraySize parameter to 0. |
Returns
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:
Value | Meaning |
---|---|
0 | Success |
Positive Values | Warnings |
Negative Values | Errors |
