Controller Base Package Software


The software is the instrument! Find out how the Nanonis software can respond to the highest demands in SPM applications. With its track record for reliability, the Nanonis controller can significantly increase day-to-day efficiency and productivity. Also, the completely redesigned user interface makes it even more enjoyable to master complex scientific experiments.

  Software Handling

The Nanonis software is based on the latest developments in programming techniques and signal processing. With its modular architecture and multi-window application all data are acquired simultaneously and transmitted to all modules at all times. Only the windows and functions necessary for the current experiment need to be open compared of an interface with a single window that often will have irrelevant sections displayed  using valuable screen real estate. The window layout and settings can be stored and recalled at the click of a button for quick experiment switching.

  Optimized User Experience

The software design has been optimized for more efficient workflow, resulting in a streamlined and simpler design. With software-instruments becoming more and more of a standard, the software departs from its hardware ties and makes any user feel at home quicker thanks to its modern, yet timeless design.

  48 Live Signals

48 signals: 8 Inputs, 8 outputs plus  internal signals, 24 of which are seamlessly accessible throughout the entire Nanonis software. Any signal can be selected in any module for feedback, spectroscopy or noise analysis. The distinction between inputs and outputs is blurred to provide a more powerful experimental platform. All operations between signals are performed in the digital domain with intuitive software-control without the drawbacks of analog signal processing. Signals are displayed in physical units using a floating point representation with assigned SI units for immediate quantitative results.

  Interactive Scan Control

Three modes are integrated in this module: 'Scan', 'Follow-me' and 'Spectroscopy'. All scan parameters can be adjusted on-the-fly without delay during scanning, and it is possible to zoom, navigate and paste multiple scanned images to the background for reference. Any of the 24 signals can be displayed in multiple windows. Pause then resume scan with no data loss after tip cleaning, spectroscopy, or manipulation. The motion of the tip is visualized in real-time when scanning or positioning with the mouse.

  Multipass scanning

Scan control supports multi-pass scanning, where a single line can be scanned multiple times with different parameters for each trip over the surface. For each pass, bias and feedback setpoint can be changed. Furthermore it is possible to record a channel, e.g. topography, and then play it back in the following path - a typical MFM application. For complete freedom and flexibility the user can call a homegrown LabVIEW program to change all settings after each pass, or combine MultipPass with scripting functions to allow very fast execution of experiments.

  2D and 3D Spectroscopy

Advanced spectroscopy modules allow for experiments at a point, along a line, a cloud or a grid, including combined grid and scanning mode that can have different pixel densities.
  • Z-spectroscopy with user-defined retract condition
  • Bias spectroscopy with up to 20’000 pixels/s, variable bias point spacing and 7 timing parameters available before, during and after the spectroscopy sweep
  • Generic sweeper: sweep one of 13 possible signals (8 physical outputs and 5 internally calculated) while recording any other channels.
  • Custom experiments programmed in the Programming Interface

  Spectrum Analyzer, Graphs and Oscilloscopes

  • dual channel oscilloscope with post- and pre-trigger 
  • spectrum analyzer: continuous display of any of the 48 channels
  • signal charts and history: rolling charts for continuous data monitoring and acquisition
  • long term spectrum: record data over hours or days to discriminate environmental effects from the microscope measurements.
All analyzers, graphs and oscilloscopes are completely independent and can run at the same time as image scans and spectroscopy allowing the same channels to be acquired in the time- and frequency domain as well as in a conventional manner simultaneously.

  Open File Format

The Nanonis file format (.sxm) for scan images, binary file format (.3ds) for experiment on a grid and ASCII file format for simple experiments are described in details in the contextual help. Most processing software such as SPIP, Mountains, Gwyddion, WSxM and SPIW open Nanonis files. The file header can be read directly in Notepad++. Matlab, Python, and LabVIEW routines are provided for customized post-data processing.
