■ Advanced Control
Whe n you click on the Advanced Control button, the Advanced Control window opens.
The Advanced Control window includes some parameters that are not often used, and
other parameters that are necessary to perform optional measurements.
The Advanced Control window has three tab windows in which you can specify detailed
parameters.
Scan tab window
Specify detailed parameters that are necessary for a scan.

When this check box is clicked on, the signal input from the ADX terminal on
the rear of the SPM CONTROL unit is added to the X-axis scanning signal.
The signal input from the ADX terminal is increased to a signal 20 times
greater in voltage through the piezo-d
ting a ± 1 V sine wave to the ADX terminal outputs ± 20 V.
The maximum input rating of the ADX terminal is ± 10 V. However, if the sum
of the input voltage and X-axis scanning voltage exceeds
voltage of the SPM CONTROL unit, the maximum X-axis scanning voltage is
saturated at the power-supply voltage.
Y Signal
When this check box is clicked on, the signal input from the ADY terminal on
the rear of the SPM CONTROL unit is added to the Y-axis scanning signal.
The signal input from the ADY terminal is increased to a signal 20 times
greater in voltage through the piezo-drive high-power amplifier. That is, input-
ting a ± 1 V sine wave to the ADY terminal outputs ± 20 V.
The maximum input rating of the ADY terminal is ± 10 V. However, if the sum
of the input voltage and Y-axis scanning voltage exceeds the power-supply
