①
Z/20 terminal
Outputs one twentieth of the output voltage of the Z-axis driving amplifier (the
voltage applied to the Z-axis piezoelectric element). This terminal is connected to
the oscilloscope.
②
CH2 terminal
Outputs the signal selected using the SPM software. This terminal is connected to
the oscilloscope.
③
ADB terminal
This is an input terminal used to add an external signal to a specimen bias signal.
The maximum input voltage is
±
10 V. However, the maximum output voltage that
can be applied to the piezoelectric scanner is
±
12 V in total (external input signal
plus internal bias signal). Check the superimposition of the input signal to the bias
voltage using the Scan window.
④
ADX terminal
This is an input terminal used to add an external signal to an X-axis scanning signal.
A voltage that is 15 times larger than the input signal voltage is applied to the
piezoelectric scanner. The maximum input voltage is
±
10 V. However, the maxi-
mum voltage that can be applied to the piezoelectric scanner is
±
150 V in total.
Check the superimposition of the input signal to the X scanner using the Scan
window.
⑤
ADY terminal
This is an input terminal used to add an external signal to a Y-axis scanning signal.
A voltage that is 15 times larger than this input signal voltage is applied to the
piezoelectric scanner. The maximum input voltage is
±
10 V. However, the maxi-
mum voltage that can be applied to the piezoelectric scanner is
±
150 V in total.
Check the superimposition of the input signal to the Y scanner using the Scan
window.
⑥
ADZ terminal
This is an input terminal used to add an external signal to a Z-axis feedback signal.
A voltage that is 15 times larger than this input signal voltage is applied to the
piezoelectric scanner. The maximum input voltage is
±
10 V. However, the maxi-
mum voltage that can be applied to the piezoelectric scanner is
±
150 V in total.
Check the superimposition of the input signal to the Z scanner using the Scan
window.

The following terminals are used for connecting optional accessories.
⑦
LOCK
Connects a lock-in amplifier for extensional use.
