RFmxWCDMA_ModAccFetchRCDEArray
int32 __stdcall RFmxWCDMA_ModAccFetchRCDEArray (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 peakRCDE[], int32 peakRCDESpreadingFactor[], int32 peakRCDECode[], int32 peakRCDEBranch[], int32 arraySize, int32* actualArraySize);
Purpose
Fetches arrays of peak relative CDE values of the active channels, of the carriers and the corresponding code numbers, spreading factors, and branches. Each element in these arrays corresponds to the peak value among the relative code domain errors of all the active channels in each carrier.
Parameters
| Input | ||||||
| Name | Type | Description | ||||
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWCDMA_Initialize function. | ||||
| selectorString | char[] | Specifies a selector string comprising of the signal name and result name. 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. Example: "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxWCDMA_BuildSignalString function to build the selector string. |
||||
| timeout | float64 | Specifies the timeout, in seconds, for fetching the specified measurement. 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. | ||||
| arraySize | int32 | Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter. | ||||
| Output | ||||||
| Name | Type | Description | ||||
| peakRCDE | float64[] | Returns the array of maximum value among the relative code domain errors (RCDEs) for all active channels. This value is expressed in dB.
The relative CDEs are computed by despreading the descrambled error vector corresponding to each active channel with the appropriate active channel codes. The RCDE is defined as the ratio of the mean power of this despread error vector to the mean power of the corresponding reference waveform. |
||||
| peakRCDESpreadingFactor | int32[] | Returns the array of spreading factors of the channel corresponding to the value of the peakRCDE parameter.
|
||||
| peakRCDECode | int32[] | Returns the array of spreading codes of the channel corresponding to the value of the peakRCDE parameter.
|
||||
| peakRCDEBranch | int32[] | Returns the array of branches of the channel corresponding to the value of the peakRCDE parameter.
|
||||
| actualArraySize | int32* | Returns the actual size of the array, if you pass NULL to all output array parameters, and set the arraySize parameter to 0. | ||||
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 RFmxWCDMA_GetError function. The general meaning of the status code is as follows:
