Nanonis Tramea: Instrument Concept
Speed and Performance
The concept behind the Nanonis Tramea™ quantum transport measurement system is a major advancement compared to the technology used in most conventional acquisition systems. Some of the most important differences are:
- FPGA and real-time data generation and acquisition: Measurements run on an FPGA or a dedicated CPU which guarantee much faster speed and perfectly constant point spacing, in contrast to slow point-by-point data acquisition
- Increased performance with FPGA-based data processing: Instruments like lock-ins, function generators and oscilloscopes are implemented in the FPGA hardware. They are not only more flexible than conventional "boxed" hardware but also allow more advanced signal processing and better signal performance
- No low-speed buses for measurement control: Conventional systems have to rely on slow data buses like GPIB or RS-232 for instrument control due to their architecture based on multiple single-purpose boxes. These slow techniques are no longer needed since data acquisition runs on a real-time system inside a single instrument.
- Separated data acquisition and data storage: Data storage and display on the measurement PC are independent from the actual measurement. The PC is no longer slowing down or influencing measurements.
- Integrated digital architecture: The integration of all functions into one platform with purely digital signal processing eliminates the need of analog signal routing and complex wiring. Operations between signals can be done much faster, in a user-friendly fashion and without risk of sample damage
- Scalable architecture: The concept and workflow do not change if the number of signals is increased or the application requires new measurement techniques. This means immediate productivity and the ability to grow with the experimental requirements without any drawback
- Dedicated state of the art hardware: The hardware delivers superior performance for quantum transport measurements since it was designed with exactly this application in mind. It uses the best components available for the application. It is not limited by requirements asking for general-purpose use.
The Nanonis Tramea™ hardware delivers stunning signal performance which was previously unthinkable for a similar multi-channel package. It offers high resolution, high precision, low noise, low drift, the highest DC and AC performance and multiple-channel functionality within a single package. This level of signal quality is only possible by combining no-compromise electronic design, meticulous component selection and advanced signal processing.
- Lower output noise than most dedicated DC sources
- Up to 48 outputs
- High-resolution DA conversion: true-20-bit analog outputs, 22-bit with hrDAC
- High resolution AD-conversion: Up to 22-bit
- 120 dB dynamic range
- Lock-ins with over 100 dB dynamic reserve
- Temperature stabilized for lowest drift
