The following table shows the required demodulation bandwidth for an error less than
0.5 dB up to a maximum AF frequency.
deemphasis
max. AF frequency
required demodulation bandwidth
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
Coupled ← AF Filter ← Left
All channels for which this option is enabled are configured identically, i.e. the channel
settings are coupled. If you change the settings for one coupled channel, the settings
are changed for all other coupled channels, as well. The settings are taken from the
first channel for which coupling is enabled.
Remote command:
[SENSe:]SFM:<ChannelType>:RSUMmary:COUPling
All AF Filter Off ← AF Filter ← Left
Disables all specified AF Filters.
Remote command:
[SENSe:]FILTer<n>:AOFF
AF Range ← Left
Opens a submenu to define the diagram scaling for AF displays.
Dev per Division ← AF Range ← Left
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).
