③ After selecting, press the
EXIT
key to release the setting mode.
The above completes DC offset modulation setting.
Other operations:
• Amplitude setting vs. maximum amplitudes
: Max. amplitude = Amplitude setting + DC offset deviation
• 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.
• Setting items at DC offset deviation (MODU menu)
