Parameters

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.

rmsEvm  Double

Upon return, contains the RMS EVM of the composite signal. This value is expressed as a percentage.

peakEvm  Double

Upon return, contains the peak value of the uplink EVM. This value is expressed as a percentage.

rho  Double

Upon return, contains the correlation of the received signal with the reference signal normalized by the signal power.

frequencyError  Double

Upon return, contains the frequency error. This value is expressed in Hz.

chipRateError  Double

Upon return, contains the chip rate error. This value is expressed in parts per million (ppm).

rmsMagnitudeError  Double

Upon return, contains the RMS magnitude error of the composite signal. This value is expressed as a percentage.

rmsPhaseError  Double

Upon return, contains the RMS phase error of the composite signal. This value is expressed in degrees (deg).
