View Data in Real Time 3D:
l
Open the Master ArGL Panel by selecting from the menu bar AFM Analysis
⇒
3D Surface Plots.
l
From the Surface pull-down select Real time
l
From the Data Type pull-down to the right of it, select the desired channel in that image (usually
Height or Zsenor).
l
Click the Do It button.
l
You can click and drag on the 3D data to change the view.
Moving the Sample Between Scans:
l
Sometimes, it is desirable to move to another point of interest after some scans have been
taken. For features within 12.5 microns, use the X Offset and Y Offset fields. Note that a neg-
ative is to the left or below the initial area.
l
For features that are further away, use the arrows toward the edges of the Video Panel. The
single arrows are slow, and the double arrows are fast. It is also possible to click and hold the
double arrows for faster, continuous movement. See
4.5 for an example of sample movement.
Note These buttons move the sample rather than the cantilever, and so the laser and objective
stay in alignment. Be sure to avoid accidentally moving the tip, and remember that the smaller
arrow buttons in the upper left hand corner of the Video Panel are set to the cantilever rather than
to the sample.
1. Q When I make changes to scanning parameters, when do those changes take effect in
the scanned image?
2. A Most parameters in the main tab of the main panel (See 1. ) will update as soon as you
make a change. Note that changing points, lines, or scan rate, will tak effect next frame.
If you check the Delay Update box just above the Setpoint parameter, then any changes you
make to parameters above that box will only update next frame. Until the image is complete, the
changed variables are highlighted in blue.
You can always force a new image by clicking Frame Up or Frame Down. A nice way to see the
effect of changing imaging parameters can be as follows:
l
Check the Delay Update box as described above.
l
Click Frame Up and collect a dozen scan lines. Observe the image quality
l
Make some changes to the scan parameters (number of points, rate, gains, setpoint).
l
Click Frame Up again.
l
Observe as the exact same scan region is ”painted over” with new data taken with your new para-
meter choices.
