Namespace: NationalInstruments.RFmx.EvdoMX
public int FetchUplinkEvm(string selectorString, double timeout, out double uplinkRmsEvm, out double uplinkPeakEvm, out double uplinkRho, out double frequencyError, out double chipRateError, out double uplinkRmsMagnitudeError, out double uplinkRmsPhaseError)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. |
| timeout | double | 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 method waits until the measurement is complete. |
| uplinkRmsEvm | out double | Upon return, contains the RMS of the EVM, as a percentage. |
| uplinkPeakEvm | out double | Upon return, contains the peak value of the uplink EVM, as a percentage. |
| uplinkRho | out double | Upon return, contains the Rho value. |
| frequencyError | out double | Upon return, contains the detected frequency error in Hz. |
| chipRateError | out double | Upon return, contains the chip rate error in parts per million (ppm). |
| uplinkRmsMagnitudeError | out double | Upon return, contains the RMS of the magnitude error, as a percentage. |
| uplinkRmsPhaseError | out double | Upon return, contains the RMS of the phase error in degrees. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
