Oscillation Controller with Integrated Digital PLL
For the finest control of mechanical oscillators
The Oscillation Controller (OC4) adds all dynamic AFM capabilities to the Nanonis Base Package. The z-feedback of the SPM controller can regulate on any signal coming from the mechanical resonator with any predifined SafeTip conditions. Imaging modes include among others: non-contact AFM, intermittent contact mode, phase imaging, dissipation. With an input bandwidth of 5MHz, the OC4 can operate any type of cantilever, tuning fork, needle sensors, etc. and their harmonics.

 |
 |
|
|
|
- Fully digital PLL up to 5MHz: no introduction of noise or drift from analog or mixed signals.
- Digitally integrated into the Nanonis control system.
- Any signal or combination can be used as z-feedback, user-defined SafeTip™ features.
- Easy access and analysis of internal signals reporting frequency shift, amplitude, phase and excitation.
- Integrated oscilloscope and spectrum analyzer (FFT) with continuous display up to 5MHz
- Demodulation bandwidth up to 5 kHz
- Frequency and phase sweep spectrum for maximum amplitude and minimum excitation.
- perfectPLL™: automatic PLL-tuning according to the Q-factor, demodulation bandwidth and gain.
- Accurate amplitude detection: lock-in technique for amplitude detection instead of RMS-to-DC conversion.
