Nanonis Tramea ™ : Instrument Concept -
Speed and Performance
The concept behind the Nanonis Tramea™ quantum transport mea-
surement system is a major advancement compared to the technology
used in most conventional measurement systems. Some of the most
important differences are: • The integration of all functions into one platform with purely dig-
ital 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.
• Real-time data generation and acquisition and FPGA-based sig-
nal processing offer massively faster speed, more flexibility and
superior signal performance compared to conventional “boxed”
hardware. Also, slow data busses like GPIB or RS-232 are no longer
necessary since data acquisition runs on a real-time system in a
single instrument. For the same reason, the measurement PC has no
influence on the measurement speed. • 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.
