AMPL Sets the sine/square/triangle waveform
amplitude. Turn left (decrease) or right
(increase).
When pulled out, attenuates the
sine/square/triangle waveform
amplitude by −20dB. The −20dB display
turns On.

This knob is available in SFG-2100
series only. It becomes effective in
sweep mode and AM/FM mode.
In Sweep mode: Sets the sweep span.
Turn left (narrow) or right (wide). The
range is 1 ~ 100. For sweep details, see
page36.
In AM/FM mode:
Sets the FM deviation (page38).
Turn left (decrease) or right (increase).
The range is over −50kHz ~ +50kHz,
centered at 1MHz.
When pulled out, sets the AM
depth (page37). Turn left (shallow) or
right (deep). The range is 0 ~ 100%.
Power switch Turns the main power On/Off. For
power up sequence, see page20.
