SPM Fundamentals for the MultiMode
Hardware
22 MultiMode SPM Instruction Manual Rev. B
Because each scanner exhibits its own unique piezo properties, each has its own parameter file.
When scanners are changed, the parameter file for the new scanner is changed along with it,
ensuring maximum accuracy at any scan size. Loading new parameter files requires only a few
seconds. Table 2.1a describes the range capabilities of each MultiMode SPM scanner.

Figure 2.1f depicts the electrode configuration used on one type of scanner piezo tube. Electrodes
are oriented as shown when the MultiMode is viewed from the front. AC signals applied to
conductive areas of the tube create piezo movement along the three major axes. With the Scan
angle parameter in the control panel set to 0.00, the fast-scan direction is in the direction of the X-
axis.
