①
EXT
This is the external oscillator input terminal for inputting a sine wave with ampli-
tude 1.0 V to this terminal. The signal applied to this terminal is adjusted to a
suitable output voltage using the SPM software and is added to the cantilever
vibration piezoelectric element. Set the frequency using an external oscillator.
②
OSCO
This terminal outputs the reference voltage (sine wave with amplitude
±
10 V) for
the voltage applied to the cantilever-vibrating piezoelectric element when the
Slope-detection method is used in the AC mode AFM operation. You can turn the
OSCO terminal on and off and change its frequency using the SPM software.
When the OSCO terminal is off, it is disconnected from the DDS, so the
terminal is virtually short-circuited to GND (0 V) through the amplifier.
Terminals for connecting optional accessories
③
LIFT
Use this terminal when connecting to the optional Q controller. TTL level HI is
output when the cantilever is lifted in the Lift mode.
④
FA3
Use this terminal when connecting to the optional Q controller.
