Nanonis Tramea software




The software is the instrument! Find out how the Nanonis Tramea™ software can respond to the highest demands in quantum transport measurements.

The Tramea™ software provides a superior “one fits all framework” with impressive embedded functionality. Yet, it is easily expandable for customized experiments using either the existing add-on modules or user-programmed functions.
Based on more than 30 man-years of development and with an excellent track record for reliability the Tramea™ software can significantly increase day-to-day efficiency and productivity.


  Software Handling

The Nanonis Tramea™ software is based on the latest developments in programming techniques and signal processing to provide a more powerful experimental platform. With its modular architecture and multi-window application all data are acquired simultaneously and transmitted to all software instruments at all times. Only the windows and functions necessary for the current experiment need to be open compared to 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.

  Live Signals

Plenty of signals: Up to 24 Inputs, up to 48 outputs and a large number of internal signals, 24 of which are seamlessly accessible throughout the entire Nanonis software. Any signal can be selected in any module for observation, acquisition or noise analysis without affecting other modules. With the modular architecture, all data are acquired simultaneously and transmitted to all software instruments at all times. 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. Up to 24 signals can be streamed to disk at full real-time speed.

  Ultrafast precise measurements

A typical transport measurement could take an enormous amount of time due to the limited speed of most  measurement systems. With Nanonis Tramea™, these measurements can be performed in a matter of minutes instead of several hours: the core module of the Tramea software is a fast sweeper module capable of two- and three-dimensional sweeps, and capable of generating and acquiring up to 20’000 points per second on 24 channels in parallel. That’s up to 1000x faster than current systems, without any compromise in signal quality. Combine the speed of a waveform generator with the performance of a precision DC source.

  Intelligent Adaptive Oversampling

Nanonis Tramea™ adds an additional degree of intelligence to data acquisition: Measurement speed can be adapted automatically to the actual value and required quality of the input signal. This results in faster measurements
for intervals where no interesting input signal is expected (e.g. just noise) and in higher quality data for the measurement ranges of interest.
  • User-selectable input ranges determine the speed of the measurement depending on the input signal value. Avoid spending precious measurement time when the signal is of no interest
  • Intelligent adaptive oversampling* automatically adjusts measurement speed so that a target signal-to-noise ratio is achieved. This ensures maximum measurement speed for a required data quality
Both methods can be used in parallel on up to 4 input signals. The most restrictive condition determines measurement speed

  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 data acquisition allowing the same channels to be acquired in the time- and frequency domain as well as in a conventional manner simultaneously.

  Signal Handling and Safety

Signal handling is designed to maximize productivity and safety of the sample at the same time.
  • All signals are displayed in physical units (SI). Calibrations take into account external divider or gain stages ensuring that the acquired data do not require any additional calibration
  • Linear combinations of output signals are easily configurable. Capacitive coupling of the sample can easily be compensated
  • Slew-rate limitations and global voltage limits can be configured individually for each output ensuring that no transients or too large voltages are applied to the sample

  Easy Customization

One of the fascinating aspects of scientific research is that experiments have their own dynamics. That requires a high degree of flexibility from the measurement system.
Nanonis Tramea™ is sufficiently open to give researchers the necessary customization possibilities, thanks to its generic TCP interface.
  • Generic TCP/IP interface allows control of most instrument functions as well as data readout
  • Direct access to Tramea™ functions over a standarized interface
  • Not bound to a specific programming language: Program Nanonis Tramea from Python, Matlab, C++ or other programming environments
A more comprehensive customization is possible with the LabVIEW Programming Interface Add-on. Fast, time-deterministic customization is available through the Scripting Add-on module.

  Quantum Dot Simulator

The quantum dot simulator lets you explore the complete Nanonis Tramea™ measurement system as if it were connected to a real quantum dot . It includes the full feature set of the software.
  • Learn the operation of the software by setting up a stability diagram measurement
  • Test the functionality of various software modules including Lock-ins, graphs and sweepers
  • Verify the correct functioning of measurement routines written in the Programming Interface, the scripting module or for the TCP interface
