# SCPI: CALCulate:AFRF:MEASurement<Instance>:MEValuation:SQUality:VOIP:DEViation
value: CalculateStruct = driver.afRf.measurement.multiEval.signalQuality.voip.deviation.calculate()

Query the signal quality results measured for the VoIP path. CALCulate commands return error indicators instead of measurement values.

return:

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

value: ResultData = driver.afRf.measurement.multiEval.signalQuality.voip.deviation.fetch()

Query the signal quality results measured for the VoIP path. CALCulate commands return error indicators instead of measurement values.

return:
