class ResultData[source]

Response structure. Fields:

  • Reliability: int: ‘Reliability indicator’

  • Iphase: List[float]: N in-phase amplitudes (IPhase) and N quadrature-phase (QPhase) amplitudes, where N is equal to the number of processed 50-symbol blocks; see ‘I/Q constellation trace points (EDR) ‘.

  • Qphase: List[float]: No parameter help available

fetch() → ResultData[source]
# SCPI: FETCh:BLUetooth:MEASurement<Instance>:MEValuation:TRACe:IQDiff
value: ResultData = driver.bluetooth.measurement.multiEval.trace.iqDifference.fetch()

Returns the values of the traces in the I/Q constellation diagrams. The mnemonics IQABs, IQDiff, and IQERr denote the absolute, differential and I/Q constellation error results. The I/Q traces are available for EDR packets (method RsCMPX_BluetoothMeas.Configure.Bluetooth.Measurement.InputSignal.btype EDR) .

return:

structure: for return value, see the help for ResultData structure arguments.
