Set Offset
SFG can add or delete offset to the sine/square/triangle
waveform, thus changing the waveform vertical position.
Use the OFFSET knob.

Turn the knob right (higher position)
or left (lower position).
The range is −5V ~ +5V for 50Ω
load.
Limitation
Note that the output amplitude, including the offset, is
still limited to:
−5 ~ +5V (50Ω load)
−10 ~ +10V (no load)
Therefore excessive offset leads to peak clip as below.
