If DC is selected, the absolute frequency is displayed, i.e. an input signal with an
offset relative to the center frequency is not displayed symmetrically with respect to
the zero line.
If AC is selected, the frequency offset is automatically corrected, i.e. the trace is
always symmetric with respect to the zero line.
●
PM signal display
If DC is selected, the phase runs according to the existing frequency offset. In addi-
tion, the DC signal contains a phase offset of ± π.
If AC is selected, the frequency offset and phase offset are automatically corrected,
i.e. the trace is always symmetric with respect to the zero line.
Remote command:
[SENSe:]ADEMod<n>:AF:COUPling
on page 122
Deviation Lin/Log ← AF Range
Switches between logarithmic and linear display of the modulation depth or the phase
deviation (Analog Demodulation only) or the frequency deviation.
Remote command:
