Nanonis Tramea signal performance


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.

Discover some of the performance highlights available with Nanonis Tramea™:

  High resolution DA conversion

Nanonis Tramea™ uses the fastest 20-bit, 1-ppm DA-converters available on the market. The patented hrDAC technology transforms these state-of-the-art converters into even higher resolution 22-bit devices.
  • true 20-bit native resolution on every output
  • 22-bit resolution with hrDAC, individually selectable for each output. Stepsize down to 5 μV with an output range of ±10 V.
  • Fully AC-capable with 40 kHz analog bandwidth
  • Smallest amplitudes possible, therefore no mixers required for DC+AC operation

  High precision

Still using 16-bit converters because higher resolution converters have poor precision?
It is no longer necessary to choose between high-resolution or high-precision outputs. The Nanonis Tramea™ outputs feature true 20-bit precision, meaning impressive 1 ppm maximum error.
  • INL error of 1 20-bit LSB (typical) meaning maximum deviation of 1 ppm from ideal behavior
  • DNL of 0.5 20-bit LSB (typical) resulting in highly constant step size over the full output range
  • High linearity down to -120 dBFS for exceptional small signal performance
  • 1 MS/s sampling rate for dynamically changing signals (lock-in, arbitrary waveforms, pulsed-gate,...)

  High resolution AD conversion

A custom-designed input stage followed by 18-bit AD-converters allows the acquisition even of the weakest analog signals while using the full input range of ±10 V. Conventional instruments would require gain switching for achieving similar results.
  • 18-bit input resolution at 1 MS/s
  • 22-bit ENOB at 1 kS/s
  • 100 kHz analog bandwidth
  • High linearity for the precise acquisition of small amplitude signals. No gain switching required.

  Low noise

When experiments require energies of just a few μeV low noise is mandatory. The Nanonis Tramea™ outputs have an extremely low noise floor below 25 nv/√Hz at ±10 V output range.
  • 25 nV/√Hz with ±10 V output range
  • Less than 170 nV RMS noise 0.1 - 10 Hz with ±10 V output range
  • Less than 10 μV RMS noise 10 Hz - 300 kHz with ±10 V output range

  Low drift with temperature stabilization

Transport measurements can last very long and it is of utmost importance to keep all signals applied to the sample as stable as possible during this time. The voltage reference of the analog electronics is temperature-stabilized for lowest drift and lowest temperature coefficient. The relative drift between different channels of the same TSC is also minimized.
  • Less than 1.5 μV drift in 12 hours
  • Less than 3 μV/°C temperature coefficient
