Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used.

timeout

Type: SystemDouble
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.

meanRmsSymbolEvm

Type: SystemDouble
Upon return, contains the RMS symbol EVM for the selected time slot and channel, averaged over all averaging iterations. This value is expressed as a percentage.

maximumPeakSymbolEvm

Type: SystemDouble
Upon return, contains the maximum value of the peak symbol EVMs, among all averaging iterations for the selected time slot and channel. This value is expressed as a percentage.

frequencyError

Type: SystemDouble
Upon return, contains the frequency error averaged over all measured slots. This value is expressed in Hz.

chipRateError

Type: SystemDouble
Upon return, contains the chip rate error. This value is expressed in ppm.

meanRmsSymbolMagnitudeError

Type: SystemDouble
Upon return, contains the RMS symbol magnitude error for the selected time slot and channel, averaged over all averaging iterations. This value is expressed as a percentage.

meanRmsSymbolPhaseError

Type: SystemDouble
Upon return, contains the RMS symbol phase error for the selected time slot and channel, averaged over all averaging iterations. This value is expressed in degrees.

meanSymbolPower

Type: SystemDouble
Upon return, contains the mean symbol power for the selected time slot and channel. This value is expressed in dB if you set the SetPowerUnit(String, RFmxTdscdmaMXCdaPowerUnit) method to dB, and in dBm if you set the CDA Pwr Unit method to dBm.
