class CalculateStruct[source]

Response structure. Fields:

  • Reliability: int: decimal ‘Conventions and General Information’. In list mode, a zero reliability indicator indicates that the results in all measured segments are valid. A non-zero value indicates that an error occurred in at least one of the measured segments.

  • Seg_Reliability: List[int]: 0 | 3 | 4 | 8 The segment reliability indicates whether one of the following exceptions occurred in this segment: 0: No error 3: Signal overflow 4: Signal low 8: Synchronization error If a combination of exceptions occurs, the most severe error is indicated.

calculate() → CalculateStruct[source]
# SCPI: CALCulate:EVDO:MEASurement<instance>:MEValuation:LIST:MODulation:SDEViation
value: CalculateStruct = driver.multiEval.listPy.modulation.standardDev.calculate()

Returns modulation single value results in list mode. To define the statistical length for AVERage, MAXimum, MINimum calculation and enable the calculation of the results use the command method RsCmwEvdoMeas.Configure.MultiEval.ListPy. Segment.Modulation.set. The ranges indicated below apply to all results except standard deviation results. The minimum for standard deviation results equals 0. The maximum equals the width of the indicated range divided by two. Exceptions are explicitly stated. The values listed below in curly brackets {} are returned for each active segment: {…}seg 1, {… }seg 2, …, {…}seg n. The number of active segments n is determined by method RsCmwEvdoMeas.Configure.MultiEval.ListPy. count. The values described below are returned by FETCh and READ commands. CALCulate commands return limit check results instead, one value for each result listed below.
