Meas Setup
FM
Pressing this key, when it is not selected, selects and activates the FM demodulation function.
Pressing it a second time branches to the FM Demod menu where FM demodulation settings can
be adjusted.

State Saved Saved in instrument state.
Initial S/W Revision Prior to A.02.00
Channel BW (FM Demod)
Sets the RBW setting used by the hardware during the demodulation period in nonzero spans.
Note that this is a separate parameter only for the demodulation function and does not affect the
RBW setting in the BW menu which is used during the normal sweep. The flat top filter type must
be used during the demodulation period. A 5 kHz Video Bandwidth filter is used.
In Zero Span, the instrument’s RBW & VBW filters are used for the demodulation; thus, the
Channel BW (and RBW filter type) will match those of the instrument. This allows gap-free
listening. The Channel BW key is grayed out and the value displayed on the key matches the
current RBW of the instrument. Upon leaving zero span, the previous setting of Channel BW and
the flattop filter type are restored.
