Description
This softkey (Option 002 only) accesses the frequency mo dulation
softkeys. These softkeys engage external and internal frequency
mo dulation. They allow you to dene the coupling, waveform, rate,
and deviation of the internal FM.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
FM On/Off Ext
Toggles on and o the frequency
mo dulation mo de for an external FM
source.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
FM On/Off Int
Toggles on and o the frequency
mo dulation mo de using the internal
FM generator.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Internal FM Rate
Sets the rate of the internal frequency
mo dulation.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Internal FM Deviation
Sets the deviation of the internal
frequency mo dulation.

FM Coupling 100kHz
Sets AC coupling for mo dulation rates
of 100 kHz or greater. The RF signal
is phase lo cked.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
FM Coupling DC
Sets DC coupling for mo dulation
rates of less than 100 kHz. The phase
lo cked lo op is op en.
