ADEMOD
CALCulate<1|2>:MARKer:FUNCtion:ADEMod:FERRor[:RESult<1...6>?]
This command queries the frequency error with FM and PM demodulation. With FM
demodulation, trace 1 to 6 is selected with the numeric suffix (:RESult<1...6>). With PM
demodulation, the frequency error is determined from the current measurement data
(CLR/WRITE trace). The numeric suffixes <1|2> are irrelevant.
The offset thus determined differs from that calculated in the [SENSe:]ADEMod:FM:OFFSet?
command since, for determination of the frequency deviation, the modulation is removed by
means of lowpass filtering, producing results that are different from those obtained by averaging
with the SENSe command.
This command is only available for traces in the FM and PM result display. If another result
display is selected, the command is disabled.
Example

ADEMOD
CALCulate<1|2>:MARKer:FUNCtion:ADEMod:FM[:RESult<1...6>?]
This command queries the results of FM modulation measurement. The numeric suffix
(:RESult<1...6>) indicates whether trace 1, 2, 3, 4, 5 or 6 is selected. The numeric suffixes
<1|2> are irrelevant.
