The oscillation controller (OC6) adds dynamic and multifrequency AFM capabilities to the Nanonis controller. With 5x the input bandwidth of the previous generation OC4 unit, the controller can handle signals from DC to 25 MHz or even 100MHz with the highest accuracy. The redesigned output signal path offers improved linearity, signal purity, and fully digital amplitude control. With user-selectable ranges and filters to reduce broadband noise and optimise signal quality for the application, it offers uncompromised performance also for signals down to DC. The high-current output stage can be bypassed for applications not requiring large driving currents, lowering noise to less than 5 nV/sqrt(Hz).

The HVA4 family is a set of high voltage amplifiers designed for nano-positioning applications using piezo elements. Three different models with maximum output voltages of ±140 V, ±220 V or ±400 V let the user choose an optimal setup for the required application. The unit has six channels featuring four inputs (X, Y, Z and AUX) divided into three groups (X&Y, Z, AUX). Each group has its individual gain selector with 4 settings. Z and AUX inputs additionally have switchable polarities.

Provides all the required supply voltages for the Nanonis HVA4 and PMD4. Up to two of these instruments can be connected to a single HVS4.

The Nanonis PMD4 piezo driver was specifically designed with low-temperature applications in mind, where slip-stick motors require very fast slip-transitions. The patented electronics of the PMD4 can provide waveforms with up to ±400V and deliver peak currents above 20 A. This results in fast transitions taking significantly less than 1 μs even at peak voltage into a real load. The very sharp transitions and high voltages also allow for simpler piezo stacks resulting in more rugged mechanical designs. The PMD4 can drive loads up to 3 μF.

Nanonis adaptation kits exist for many commercially available UHV SPMs including those from SPECS themselves, as well as Omicron, RHK, JEOL, Unisoku and Bruker.

The original microscope cables connect directly to the pin-compatible interface, which makes it extremely simple to connect the control system to the microscope. The adaptation kit powers both STM and AFM pre-amplifiers and switches current and bias gains. In the case of beam deflection AFM models, the laser diode is monitored directly by the Nanonis software and the beam-deflection module displays the signals from the photo-detector. Control of inertial motors (x, y, z, mirrors and PSD) for coarse motion as well as automatic approach is seamlessly integrated in the Nanonis software and requires the Nanonis Piezo Motor Driver (PMD4).

The power of lego blocks: Build a fully customized experiment in LabVIEW or any other programming language

Script your own high-speed measurement sequences on the real-time system with scripting module SI 5. When speed and precise timing matter, measurement routines just can’t be fast enough. With a time-deterministic approach and 50 μs time interval between commands, scripting significantly boosts execution speed and reduces measurement time. The module is seamlessly integrated in standard measurement modules: Scripts can be easily called from other modules, and custom functions or pre-defined measurement can be started from within a script. The scripting module is not intended as a replacement of the Nanonis Programming Interface, but as complementary module: It allows 100x faster execution speed while the Programming Interface offers more flexibility.

The atom tracking module is designed to track topographical features (not only atoms) dynamically and can therefore measure and compensate for thermal drift and sample tilt. A fully automated procedure automatically calculates drift velocity and sample tilt in both X and Y-directions as well as drift in Z-direction and compensates for these. This module is of particular interest when the tip position has to follow a local extremum (e.g. an atom or molecule, maximum or minimum) between point-spectroscopy or when scanning a small scan area where drift is highly noticeable.
