class CalculateStruct[source]

Response structure. Fields:

  • Reliability: int: ‘Reliability indicator’

  • Mod_Type: enums.ResultStatus2: DBPSk1: 1 Mbit/s DBPSK DQPSk2: 2 Mbit/s DQPSK CCK5: 5.5 Mbit/s CCK CCK11: 11 Mbit/s CCK

  • Plcp_Type: enums.ResultStatus2: Short or long PLCP

  • Payload_Length: enums.ResultStatus2: No parameter help available

  • Burst_Power: enums.ResultStatus2: No parameter help available

  • Evm_Peak: enums.ResultStatus2: Error vector magnitude peak value

  • Evm: enums.ResultStatus2: No parameter help available

  • Freq_Error: enums.ResultStatus2: Center frequency error

  • Clock_Error: enums.ResultStatus2: Chip clock error

  • Iq_Offset: enums.ResultStatus2: No parameter help available

  • Gain_Imbalance: enums.ResultStatus2: Gain imbalance

  • Quad_Error: enums.ResultStatus2: Quadrature error

  • Out_Of_Tol: enums.ResultStatus2: Out of tolerance result, i.e. the percentage of measurement intervals of the statistic count for modulation measurements exceeding the specified modulation limits.

  • Burst_Rate: enums.ResultStatus2: If a modulation filter is used, the burst rate indicates the share of bursts of the selected modulation format in the bursts received. Otherwise, it returns 1.

# SCPI: CALCulate:WLAN:MEASurement<Instance>:MEValuation:MODulation:DSSS:SDEViation
value: CalculateStruct = driver.wlanMeas.multiEval.modulation.dsss.standardDev.calculate()

Return the current, average, minimum, maximum and standard deviation single value results for DSSS signals. 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.

return:

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