Parameters

selectorString

Type: SystemString
Pass an empty string. The signal name that is passed when creating the signal configuration 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.

rmsSymbolEvm

Type: SystemDouble
Upon return, contains the RMS ymbol EVM of the configured measurement channel. This value is expressed as a percentage.

peakSymbolEvm

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

rmsSymbolMagnitudeError

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

rmsSymbolPhaseError

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

meanSymbolPower

Type: SystemDouble
Upon return, contains the mean symbol power of the configured measurement channel. This value is expressed in dB or dBm.

frequencyError

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

chipRateError

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