Later al-Modulation FFM mea
• Source signal
Since the source signal of the Lateral-Modulation FFM measurement tab window is
set for measuring lateral-modulation FFM, you need not set it. The measurement
pixels are fixed at 256 × 256. When measurement starts, the images appear as
follows:
• Source Gain
The same as that in the AC-AFM tab window.
• Lo
ck-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 lateral-modulation FFM. Details
on setting the lock-in amplifier will be provided later.

You can confirm the scan mode and source-signal settings at lateral-modulation
FFM measurement from the Lateral-Modulation FFM measurement tab win-
dow by moving directly to the advanced setting tab window.
Scan mode:
Measurement mode:
Source signal 1:
Source signal 2:
Source signal 3:
Source signal 4:
Although the scan mode is 4 Inputs during lateral-modulation FFM measure-
ment, source signal 4 is ignored, and the system actually acquires 3 images si-
multane ously.
