Agilent 5500 SPM User’s Guide 176
cantilever modulation that results from this applied signal is monitored
as a measure of the sample’s elastic properties.
Force Modulation is a contact imaging mode and the Deflection signal
will be routed to the feedback loop.
Choose Mode > Force Modulation, then choose Controls > AC Mode to
open the Force Modulation Controls window:
Figure 119 Force Modulation Controls window
In Force Modulation Mode, Lock-in 1 is enabled, with the Deflection
channel as its input. The following settings are also available:
Amplitude Displays the amplitude, in volts, of cantilever
deflection.
Drive (%) The amplitude of the lock-in drive signal, stated as
a percentage (0-100 %) of the maximum available
10 V.
Frequency (kHz) Displays the frequency of the lock-in signal.
Gain Multiplies the output of the lock-in by the selected
factor. Use a larger multiplier to improve the
signal-to-noise ratio for a small signal. Ensure that
the gain will not result in an amplitude exceeding
