When selection is complete, press the
EXIT
key to release the setting mode.
The above completes setting of the amplitude modulation.
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.
• Amplitude setting vs. maximum or minimum amplitudes
:
Max. amplitude = Amplitude setting
÷
2 [1 + (depth %
÷
100)]
Min. amplitude = Amplitude setting
÷
2 [1
−
(depth %
÷
100)]
• At 0 % depth, the output amplitude is 1/2 the setting. At 100 % depth, the output amplitude is the
same as the setting.
• During modulation, if the oscillation mode of the other channel is changed, modulation stops.
• To start or stop a modulation operation on both channels simultaneously by manual operation
or via remote control (GPIB or USB), set both channels to modulation mode and set
OPER-COMMON to on.
