frequency of Lock-in 1 to determine the resonance
frequency of the cantilever.
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
10 V, beyond which the signal will be clipped. The
default value is x1 (the amplitude times 1).
Drive Mechanism
The mechanism (AAC, MAC or Top MAC) used
on the microscope.
Zero Phase
Sets the phase at the current frequency to zero,
making it easier to interpret phase changes from
the current value.
Q Control On
By applying a phase-shifted version of the
cantilever deflection signal on top of the drive
signal, Q control can either increase or decrease
the effective quality factor of the system. Select
this
On
check box to enable the Q Control
feedback loop. By default, Q Control is turned
Off.
Drive (%)
Sets the amplitude of the Q Control phase-shifted
signal, stated as a percentage (0-100 %) of the
maximum available.
Optimize
Sets the optimal Q-Control Phase Shift and Drive.
When you initiate the approach, the Amplitude 1 and Phase 1 signals
will be routed through the Deflection and Friction channels,
respectively, to the main controller. During the laser and detector
alignment procedure the
Pass Through
check boxes will be selected to
