Relative to current value (Standard, Advanced)
When active, the Start and the End values are added to the value the mod-
ulated output had before starting the modulation.
When the Tip Potential is modulated, the current value is the Tip voltage
set in the Z-Controller panel.
When the Z-Axis is modulated, the current value is the sample surface
height, as measured using the Z-Controller output. Otherwise, the meas-
urement z-position is given by the value of the Ref. Z-Plane in the Imaging
Panel.
Modulation time (Easy, Standard, Advanced)
The time used to change the Modulated output from the Start to the End
value.
Keep Z-Controller active (Advanced)
The Z-Controller will continue to change the Z-position so as to keep tip-
sample interaction constant. This option is not available when the Modu-
lated output is set to the Z-Axis.
This setting can for example be used to measure tip current as a function of
applied voltage whilst keeping the tip-sample force constant.
Measurement (Easy, Standard, Advanced)
Data points (Easy, Standard, Advanced)
The number of data points in one spectroscopic measurement. The data
points are equally distributed over the modulation range.
Averages (Easy, Standard, Advanced)
The number of times the modulation is repeated to obtain an averaged
spectroscopic measurement. The measurement results of aborted modula-
