# SCPI: FETCh:AFRF:MEASurement<Instance>:MEValuation:DEMLeft:AFSignal:DEViation
value: float = driver.afRf.measurement.multiEval.demodLeft.afSignal.deviation.fetch()

Query the AF frequency results for the left demodulator channel. For FM stereo, these results are related to the left audio channel.

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

return:

frequency: Frequency of the AF signal Unit: Hz

read() → float[source]
