Quick questions

You should be able to answer these questions without too much difficulty after studying this TLP. If not, then you should go through it again!

1. Which operating mode allows for the fastest scanning speeds?

a. Contact mode

b. Tapping mode

c. Non-contact mode

Answer: A

Deeper questions

The following questions require some thought and reaching the answer may require you to think beyond the contents of this TLP.

2. If high frequency noise is seen in an image, what should be done?

a. Increase the feedback gains

b. Decrease the feedback gains

c. Change the tip

d. Recalibrate the AFM

Answer: B. This is due to oscillation of the feedback circuit when the gains are set too high.
