I am a graduate student from Georgia Tech. We have a Multimode SPM with an E type piezo tube. We need to learn the frequency response of the piezo in z direction and/or the transfer function of the piezo. Is this information available to users? If so how can I obtain it?
Best Regards,
Giray
This is easy to do with a NanoScope V. Here is a quick recipe:
1) Engage on the surface in contact mode.
2) Use the Generic Lockin feature and set Lock-In 1 to drive Z and Vertical as the input (see attached image)
3) Sweep
You should see the main resonance around ~12 kHz.
Hope this helps,
Fritz
