class StandardDevCls

StandardDev commands group definition. 5 total commands, 1 Subgroups, 3 group commands

calculate() → List[ResultStatus2]

# SCPI: CALCulate:GPRF:MEASurement<Instance>:POWer:SDEViation
value: List[enums.ResultStatus2] = driver.power.standardDev.calculate()

Returns power results for all segments, see ‘Results in list mode’.

INTRO_CMD_HELP: The following results can be retrieved:

• ‘Current RMS’ (…:POWer:CURRent?)

• ‘Current Min.’ (…:MINimum:CURRent?)

• ‘Current Max.’ (…:MAXimum:CURRent?)

• ‘Average RMS’ (…:AVERage?)

• ‘Minimum’ (…:PEAK:MINimum?)

• ‘Maximum’ (…:PEAK:MAXimum?)

• ‘Standard Deviation’ (…:SDEViation?)

The values described below are returned by FETCh and READ commands. CALCulate commands return error codes instead, one value for each result listed below.

Use RsCmwGprfMeas.reliability.last_value to read the updated reliability indicator.

return:

power_std_dev_cur: float Comma-separated list of power values, one value per measured segment Unit: dBm (SDEViation: dB)

fetch() → List[float]

# SCPI: FETCh:GPRF:MEASurement<Instance>:POWer:SDEViation
value: List[float] = driver.power.standardDev.fetch()

Returns power results for all segments, see ‘Results in list mode’.
