RF and Microwave Instrumentation

Agilent Network Analyzer

Experimental Set-ups and Techniques

We have implemented several ready to use set-ups and techniques, some of them also in combination with the cryomagnetic systems and the RF and MW Instrumentation above.

  • Lakeshore TTPX Cryogenic Probe Station, equipped with 4 DC probes and nano-electronics for current measurements in the picoampere range.

  • Home-made etherodyne spectrometer for single-tone, pulsed-wave transmission spectroscopy (6-10 GHz)
  • Microwave components and electronics for single-tone and two-tone continuous-wave transmission spectroscopy (0-18 GHz)

Additional Equipments and facilities

  • Optical and UV light sources with diffraction grating (300-750 nm)
  • Omicron LDM 375/670 Laser Source
  • KS 4123 wedge bonder
  • Sample fabrication is available at the building by means of shared optical litography and nano-lithography (EBL, FIB and RIE) laboratories.
  • Additional spectroscopic techniques are available in the same building at Centro Interterdipartimentale Grandi Strumenti (CIGS) upon request.
  • An additional machine shop service with mechanical, electrical and informatic expertise is also available in the building.

Measurements Control and Automation

Example of an home-made python-based Graphical User Interface.

We currently use the Python Programming Language and Anaconda distribution to implement the control and automation of our instruments and measurements, exploting available frameworks (e.g. QCoDes) as well as home-made software. We also have experience on National Instruments LabVIEW for some applications.
