③
After making a selection, press the
EXIT
key to exit function setting.
The above completes frequency modulation setting.
Other operations:
• When the oscillation mode is changed to modulation (MODU), modulation occurs at the setting at that
time point.
To stop modulation: Press the
STOP
key. Resume modulation by pressing the
START
key.
• During modulation, if the oscillation mode of the other channel is changed, modulation stops.
• To start or stop modulation of both channels simultaneously on a manual operation or via
remote control (GPIB or USB), set both channels to modulation mode and set OPER-COMMON to
on.
If the BOTH lamp is on, behavior is the same even though OPER-COMMON is off.
