- calculate() CalculateStruct [source]
# SCPI: CALCulate:WLAN:MEASurement<Instance>:MEValuation:MODulation:CURRent value: CalculateStruct = driver.multiEval.modulation.current.calculate()
Return the single value results for OFDM SISO measurements. For MIMO measurements, the stream/antenna-independent values are returned. For 80+80 MHz signals, the segment-independent values are returned. There are current, average, minimum, maximum and standard deviation results. 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.
