class CalculateStruct[source]

Response structure. Fields:

  • Reliability: int: ‘Reliability indicator’

  • 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.

  • Mcs_Index: enums.ResultStatus2: Modulation and coding scheme index

  • Mod_Type: enums.ResultStatus2: No parameter help available

  • Payload_Sym: enums.ResultStatus2: Number of OFDM symbols in the payload of the measured burst

  • Measured_Sym: enums.ResultStatus2: Number of measured payload OFDM symbols

  • Payload_Bytes: enums.ResultStatus2: Number of bytes in the payload of the measured burst.

  • Guard_Interval: enums.ResultStatus2: SHORt, LONG: short or long guard interval (up to 802.11ac) GI08, GI16, GI32: 0.8 μs, 1.6 μs, and 3.2 μs guard interval durations (for 802.11ax)

# SCPI: CALCulate:WLAN:MEASurement<Instance>:MEValuation:MODulation:MINimum
value: CalculateStruct = driver.wlanMeas.multiEval.modulation.minimum.calculate()

Return the single value results for OFDM SISO measurements. For MIMO measurements, the stream/antenna-independent values are returned. 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:
