Description
This
softkey
(Option 002 only) activates the frequency modulation
mode for an external source. The FM source is connected to the FM
modulation connector. The FM sensitivity function is active. It is
factory preset to 10 MHz/V. Use the numeric entry keys, arrow keys,
or rotary knob to change the sensitivity to 100
kHz/V
or 1 MHz/V.
When external FM is in effect, the RF output is frequency modulated
with a rate and depth set by the external source. The FM coupling
is controlled by the following softkeys: FM Coupling
1OOkHz
FM Coupling DC!.
The FM coupling defaults to 100 kHz. This is AC
coupling for FM rates of 100 kHz or greater. For modulation rates
below 100 kHz, choose DC-coupled FM.
An asterisk next to the key label indicates that external FM is active
and
FM
is displayed on the message line.
For synthesizers without Option 002, see FM
