• Lock-in amplifier setting button
This button opens the Lock-in Amplifier Control window, which sets the extended
lock-in amplifier that is necessary for measuring viscoelasticity. Details on setting
the lock-in amplifier will be provided later.

You can confirm the scan mode and source-signal settings at viscoelasticity
measurement from the Viscoelasticity measurement (KFM) tab window by
moving directly to the advanced setting tab window.
