int32 __stdcall RFmxWCDMA_ACPFetchTotalCarrierPower (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64* totalCarrierPower);

Purpose

Fetches the total carrier power for the ACP measurement.

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.
Output
Name Type Description
totalCarrierPower float64* Returns the sum of all active carrier powers, where each carrier power corresponds to the value of the RFMXWCDMA_ATTR_ACP_RESULTS_CARRIER_ABSOLUTE_POWER attribute. This value is expressed in dBm. For a single-carrier measurement, total carrier power is the same as carrier absolute power.

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:

Value Meaning
0 Success
Positive Values Warnings
Negative Values Errors
