Observation of Later
You can perform lateral modulation FFM measurement by additionally installing the
optional Extended Lock-in Amplifier. When the lock-in amplifier is connected to the
SPM controller, you have to set the instrument using the software to display the tab
window for lateral modulation FFM measurement.
rvation of a topography image
You first observe the topography image of the specimen surface, and confirm that you
can obtain a good image. T
ng Lock-in Amplifier
Set the lock-in amplifier as you did in Sect. 5.5.3 when you observe an image in the
lateral modulation FFM measurement tab window.
Carry out the AFM observation using the Contact mode according to the
usual method.
Confirm that you can observe well the AFM topography image.
When scan is finished, specify parameters according to the settings of the
rs window.
