# SCPI: CALCulate:AFRF:MEASurement<Instance>:MEValuation:DEModulation:FDEViation:DEViation
value: CalculateStruct = driver.afRf.measurement.multiEval.demodulation.fdeviation.deviation.calculate()

Queries the demodulation results for FM or FM stereo demodulation. A statistical evaluation of the frequency deviation or multiplex deviation is returned. CALCulate commands return error indicators instead of measurement values.

return:

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