3.2.3.4 XY Parameters
Adjusting these parameters will alter the voltages applied to
the X and Y ceramics, which can be used for measuring and
reducing Z noise in images (see Appendix D for instructions
on how to complete a Noise Floor). XY HV Gain allows gain
reduction of the X and Y high-voltage amplifiers, similar to Z
HV Gain. Reducing the X and Y GPID settings will decrease
strain gauge activity. This will affect linearization, but will also
reduce the noise floor of the system.
3.2.3.5 Other Controls
1.
Beeper: Enables a beeper that notifies an operator that a scan is completed with an
audible tone. (Speakers must be enabled)
2.
Amplitude Value: Displays the current Z amplitude used in Tip Approach. This value
should correspond with the Selected Frequency on the Pre Scan tab.
3.
Feedback Limit: This function controls the feedback LED that turns green when Tip
Approach has achieved feedback. If the feedback light is flickering when the tip is in
feedback, increase this value by 0.01V.
4.
Extend Factor: This function determines the percent decrease of vibrational amplitude
of the probe in vibrating mode. The typical range for extend factor is 0.7-0.95, with 0.95
creating a 5% reduction in vibrational amplitude for high resolution scanning.
5.
Extend Delta: This function determines the amount of probe deflection on the surface
in non-vibrating mode. Extend delta is typically 0.1, meaning the Top-Bottom signal will
deflect by 0.1V before feedback is initiated.
6.
Tip Approach motor jog: This function will appear in the Other Controls sub-window
when the advanced tip approach options are not visible.
