# SCPI: CALCulate:AFRF:MEASurement<Instance>:MEValuation:SQUality:DEMLeft:CURRent
value: CalculateStruct = driver.afRf.measurement.multiEval.signalQuality.demodLeft.current.calculate()

Query the signal quality results measured for the left demodulator channel. For FM stereo, these results are related to the left audio channel. CALCulate commands return error indicators instead of measurement values.

return:

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

fetch() → ResultData[source]
# SCPI: FETCh:AFRF:MEASurement<Instance>:MEValuation:SQUality:DEMLeft:CURRent
value: ResultData = driver.afRf.measurement.multiEval.signalQuality.demodLeft.current.fetch()

Query the signal quality results measured for the left demodulator channel. For FM stereo, these results are related to the left audio channel. CALCulate commands return error indicators instead of measurement values.

return:

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

read() → ResultData[source]
# SCPI: READ:AFRF:MEASurement<Instance>:MEValuation:SQUality:DEMLeft:CURRent
value: ResultData = driver.afRf.measurement.multiEval.signalQuality.demodLeft.current.read()

Query the signal quality results measured for the left demodulator channel. For FM stereo, these results are related to the left audio channel. CALCulate commands return error indicators instead of measurement values.
