calculate() → CalculateStruct[source]
# SCPI: CALCulate:WLAN:MEASurement<Instance>:MEValuation:MODulation:DSSS:SDEViation
value: CalculateStruct = driver.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.
