ull-down menu.
You can select measurement modes that are av
p
ailable in the contact AFM such as
viscoelasticity, lateral modulation FFM and electrostatic force measurements. The

from the pull-down menu.
Fback Filter/Hz is the parameter that determines the response speed of the feedback
circuit. The larger the specified value is, the faster the response speed becomes, thus
producing a sharp image, but the feedback circuit easily oscillates. Usually, select
the highest speed at which the feedback circuit does not oscillate while watching an
image during scanning.
