RFmxWLAN_OFDMModAccFetchPEAveragePower
int32 __stdcall RFmxWLAN_OFDMModAccFetchPEAveragePower (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64* PEAveragePowerMean);
Purpose
Fetches the average power of the packet extension field.
Use "segment<n>/chain<k>" as the selector string to read results from this function.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWLAN_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name, result name, segment number, and chain number. 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: "segment0/chain0" "signal::sig1/segment0/chain0" "signal::sig1/result::r1/segment0/chain0" "result::r1/segment0/chain0" You can use the RFmxWLAN_BuildChainString 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. |

| Name | Type | Description |
| PEAveragePowerMean | float64* | Returns the average power of the packet extension field. This parameter is applicable for 802.11ax signals. When you set the
RFMXWLAN_ATTR_OFDMMODACC_AVERAGING_ENABLED attribute to RFMXWLAN_VAL_OFDMMODACC_AVERAGING_ENABLED_TRUE, this parameter returns the mean of the packet extension field average power results computed for each averaging count. This value is expressed in dBm.

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 RFmxWLAN_GetError function. The general meaning of the status code is as follows:
