R&S FSV-K7/K7S
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
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:
DISPlay[:WINDow<n>]:TRACe<t>:Y:SPACing
Unit ← AF Range
Opens a submenu to define the modulation unit.
Phase Unit (Rad/Deg) ← Unit ← AF Range
Sets the phase unit to rad or deg for displaying PM signals.
Remote command:
UNIT:THD
THD Unit (% / DB) ← Unit ← AF Range
Sets the unit to percent or DB for THD measurements.
Remote command:
UNIT:THD
Abs. Dev Unit (kHz/dBm) ← Unit ← AF Range
Sets the unit for absolute deviation to kHz or dBm. This softkey is only available with
the FM Stereo option K7S.
Remote command:
UNIT:ADEV
Rel. Dev Unit (dB / %) ← Unit ← AF Range
Sets the unit for relative deviation to dB or percent. This softkey is only available with
the FM Stereo option K7S.
Remote command:
UNIT:RDEV
Unit
Opens a submenu to define the modulation unit.
