RFmxEVDO_CDAFetchUplinkCodeDomainIAndQPower
int32 __stdcall RFmxEVDO_CDAFetchUplinkCodeDomainIAndQPower (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64* IMeanActivePower, float64* QMeanActivePower, float64* IPeakInactivePower, float64* QPeakInactivePower);
Purpose
Fetches the I and Q mean active powers and the I and Q peak inactive powers.
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. |
| IMeanActivePower | float64* | Returns the average power of all active code channels measured on the I-branch. If you set the CDA Power Unit attribute to dBm, the measurement returns the absolute measured power in dBm. Otherwise, the measurement returns the value relative to the total power in dB.
|
| QMeanActivePower | float64* | Returns the average power of all active code channels measured on the Q-branch. If you set the CDA Power Unit attribute to dBm, the measurement returns the absolute measured power in dBm. Otherwise, the measurement returns the value relative to the total power in dB.
|
| IPeakInactivePower | float64* | Returns the largest measured code power among the set of inactive channels on the I-branch, and in the code domain of the base spreading factor. The base spreading factor depends on the configured physical layer subtype, and is 16 for subtype 0/1; 32 otherwise. If you set the CDA Power Unit attribute to dBm, the measurement returns the absolute measured power in dBm. Otherwise, the measurement returns the value relative to the total power in dB.
|
| QPeakInactivePower | float64* | Returns the largest measured code power among the set of inactive channels on the Q-branch, and in the code domain of the base spreading factor. The base spreading factor depends on the configured physical layer subtype, and is 16 for subtype 0/1; 32 otherwise.

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:
