R&S FSV-K7/K7S
For higher AF frequencies the demodulation bandwidth must be increased.
Remote command:
[SENSe:]FILTer<n>:DEMPhasis[:STATe]
[SENSe:]FILTer<n>:DEMPhasis:TCONstant
SFM:
[SENSe:]SFM:<ChannelType>:FILTer:DEMPhasis:STATe
[SENSe:]SFM:<ChannelType>:FILTer:DEMPhasis:TCONstant
All AF Filter Off ← AF Filter ← AM
Disables all specified AF Filters.
Remote command:
[SENSe:]FILTer<n>:AOFF
AF Range ← AM
Opens a submenu to define the diagram scaling for AF displays.
Dev per Division ← AF Range ← AM
Opens an edit dialog box to set the modulation depth or the phase deviation (Analog
Demodulation only), or frequency deviation per division:
AM display:
FM display:
PM display:
The softkey is not available if logarithmic display is set ( "Deviation Lin/Log" softkey).
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:PDIVision
Reference Position ← AF Range ← AM
Determines the position of the reference line for the modulation depth or the phase
deviation (Analog Demodulation only) or frequency deviation on the y-axis of the dia-
gram. By default, this line is set to 0.
The position is entered as a percentage of the diagram height with 100 % correspond-
ing to the upper diagram border. The default setting is 50 % (diagram center) for the
display of the AM, FM, or PM signal, and 100 % (upper diagram border) for the AF
spectrum display of the AM, FM, or PM signal.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RPOSition
Reference Value ← AF Range ← AM
Determines the modulation depth or the phase deviation (Analog Demodulation only)
or the frequency deviation at the reference line of the y-axis. The reference value is set
separately for each display of the AM, FM, and PM signal and the AF spectrum of the
AM, FM, and PM signal.
