RFmxEVDO_CDAFetchUplinkSymbolPowerTrace
int32 __stdcall RFmxEVDO_CDAFetchUplinkSymbolPowerTrace (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float32 symbolPowers[], int32 arraySize, int32* actualArraySize);
Purpose
Returns the symbol power trace of the configured measurement channel.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxEVDO_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. Examples: "" "signal::sig1" You can use the RFmxEVDO_BuildSignalString function to build the selector string. |
| timeout | float64 | 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. |
| symbolPowers | float32[] | Returns the real signal values stored in an array. |
| 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. |
| 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 RFmxEVDO_GetError function. The general meaning of the status code is as follows:
