Spectrum Instrumentation for Quantum Research

Case Study: AWG used for Quantum Research | Spectrum   Precision is always important in research and there can be few research areas needing greater precision than that of quantum research. The Institute for Quantum Optics and Quantum Information at the University of Innsbruck, Austria needed an Arbitrary Waveform Generator (AWG) to generate a wide variety of signals for their research. Radio Frequency Regime The first application is applying a multiple-frequency signal in the radio frequency regime. Each frequency component is realised using a sinusoidal function.  The resulting beat signal is used to simultaneously address individual ions in a trapped-ion quantum simulator. The ion trap is shown in figures 1 and 4. Christine Maier, a researcher at the Institute, explains, “We are doing the quantum simulation with trapped, cooled calcium ions, for which single-ion addressability is essential. To achieve this, we send a laser beam through an acousto-optic deflector (AOD). […]

Real-time antenna gain and TRP measurements from a chamber on your desktop

Our webinar “Real-time antenna gain and TRP measurements from a chamber on your desktop” is available to watch-on-demand Calgary, AB, Canada – September 13, 2017: Did you miss our live webinar and want to learn how very-near-field systems can accurately evaluate antenna performance including gain measurements in seconds on your desktop. Now, our webinar is available to watch-on-demand. Click here to watch. Overview: EMSCAN’s RFxpert is a desktop very-near-field test system that is able to accurately measure radiated power and efficiency for antennas. This system allows designers to easily and quickly check antenna and wireless device performance without always needing to resort to a chamber. New software developed for RFxpert to convert between the very-near-field and the far-field has shown that radiation patterns can now be measured more accurately. These improvements to pattern accuracy mean that gain measurements can now be reliably done on the desktop scanners provided by EMSCAN again reducing the […]
