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.

rmsSymbolEvm  Double

Upon return, contains the RMS symbol EVM of the configured measurement channel. This value is expressed as a percentage.

peakSymbolEvm  Double

Upon return, contains the peak symbol EVM of the configured measurement channel. This value is expressed as a percentage.

rmsSymbolMagnitudeError  Double

Upon return, contains the RMS symbol magnitude error of the configured measurement channel. This value is expressed as a percentage.

rmsSymbolPhaseError  Double

Upon return, contains the RMS symbol phase error of the configured measurement channel. This value is expressed in degrees.

meanSymbolPower  Double

Upon return, contains the mean symbol power of the configured measurement channel. This value is expressed in dB, when you set the SetPowerUnit(String, RFmxCdma2kMXCdaPowerUnit) method to dB, and in dBm, when you set the CDA Pwr Unit method to dBm.

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).
