int32 __stdcall RFmxCDMA2k_CDAFetchSymbolPhaseErrorTrace (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float32 symbolPhaseError[], int32 arraySize, int32* actualArraySize);

Purpose

Returns the symbol phase error 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 RFmxCDMA2k_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.
Examples:
""
"signal::sig1"
"result::r1"
"signal::sig1/result::r1"
You can use the RFmxCDMA2k_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
symbolPhaseError float32[] Returns the array of symbol phase error values of the configured measurement channel. This value is expressed in degrees.
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 RFmxCDMA2k_GetError function.

The general meaning of the status code is as follows:

Value Meaning
0 Success
Positive Values Warnings
Negative Values Errors
