Scan Axis, Maximum scan ranges
X/Y/Z-Axis Range
The calibration values of each of the scanner axes. The calibration values are
given as the maximum motion range of the scanner (when Overscan is set
to 0%).
Set
Opens the scan axis correction dialog (see next section).
Scan Axis, Axis Orthogonality
The X- and Y-Axes of the scanner are generally not perfectly orthogonal,
and their orientation with respect to the AFM housing may vary. The easy-
Scan software corrects these errors by adding/subtracting some of the X
scanner command signal to the Y scanner command signal and vice versa.
X/Y Angle
The angle between then the X and Y axis of the scanner hardware. The
software uses this value to correct the scan command signals such that the
scan axes are orthogonal.
Rotation
The angle between the X axis of the scanner and the X axis of the micro-
scope body (figure
Scanner coordinate system (p.86)). The software uses this
value to correct the scan command signals such that the scan axis is parallel
to the X axis of the microscope body.
I/O Signals, Maximum input signal values
Deflection
The calibration of the cantilever deflection signal.
Amplitude
The calibration value of the cantilever vibration amplitude signal.
Phase
The calibration value of the cantilever vibration phase shift signal.
Tip current
The calibration value of the internal Tip current measurement
