11.4.8.1 Basic Demodulation Settings
The basic demodulation measurement parameters define how the measurement is
performed.
Useful commands described elsewhere:

chapter 11.4.8.2, "Time Domain Zoom Settings", on page 256
Basic demodulation commands:
[SENSe:]ADEMod<n>:AF:COUPling................................................................................255
[SENSe:]ADEMod:PM:RPOint[:X]....................................................................................255
[SENSe:]ADEMod:SQUelch[:STATe]............................................................................... 256
[SENSe:]ADEMod:SQUelch:LEVel...................................................................................256
[SENSe:]ADEMod<n>:AF:COUPling <Coupling>
This command selects the coupling of the AF path of the analyzer in the specified win-
dow.
Parameters:
<Coupling> AC | DC
*RST: AC (PM); DC (FM)
Example:
ADEM:AF:COUP DC
Switches on DC coupling.
Manual operation: See "AF Coupling" on page 108
[SENSe:]ADEMod:PM:RPOint[:X] <Time>
This command determines the position where the phase of the PM-demodulated signal
is set to 0 rad. The maximum possible value depends on the measurement time
selected in the instrument; this value is output in response to the query
ADEM:PM:RPO:X? MAX.
