Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies a selector string comprising of the result name, segment number, and chain number. If you do not specify the result name, the default result instance is used. Example: |
| timeout | double | Specifies the timeout 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 method waits until the measurement is complete. This value is expressed in seconds. |
| vhtSigAPeakPowerMaximum | out double | Upon return, contains the peak power of the VHT-SIG-A field. When you set the SetAveragingEnabled(string, RFmxWlanMXOfdmModAccAveragingEnabled) method to True , this method returns the maximum of the VHT-SIG-A field peak power results computed for each averaging count. This value is expressed in dBm. |
| vhtStfPeakPowerMaximum | out double | Upon return, contains the peak power of the VHT-STF field. When you set the OFDMModAccAveragingEnabled method to True , this parameter returns the maximum of the VHT-STF peak power results computed for each averaging count. This value is expressed in dBm. |
| vhtLtfPeakPowerMaximum | out double | Upon return, contains the peak power of the VHT-LTF field. When you set the OFDMModAccAveragingEnabled method to True , this parameter returns the maximum of the VHT-LTF peak power results computed for each averaging count. This value is expressed in dBm. |
| vhtSigBPeakPowerMaximum | out double | Upon return, contains the peak power of the VHT-SIG-B field. When you set the OFDMModAccAveragingEnabled method to True , this parameter returns the maximum of the VHT-SIG-B field peak power results computed for each averaging count. This value is expressed in dBm. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
