(ITA) Come effettuare misure Deep-Level Transient Spectroscopy (DLTS) tramite Impedance Analyzer MFIA

on 18.03.2021 at 08:30 by Roberto Foddis on Blog di Roberto Foddis
Obiettivo: produrre un treno di impulsi quadri di tensione e misurare transitori di capacità. Questo articolo illustrerà come produrre un’onda quadra in tensione ed acquisire i conseguenti transitori di capacità, in una scala temporale molto corta (ad esempio 20 us), […]

Practical active qubit reset

on 05.03.2021 at 15:48 by andrea on Blog of Andrea Corna
Practical active qubit reset When working with qubits, it’s essential to have a reliable state preparation. The easiest method for superconductive qubits is to passively wait for the qubit to decay into its ground state, but it’s slow and has […]

Webinar summary with Q&A – Probing local magnetic field patterns

on 26.02.2021 at 15:04 by Jelena on Blog of Jelena Trbovic
In this webinar we teamed up with Prof Martino Poggio who’s work focuses on understanding the physics of materials and phenomena that is strongly dependent on the local conditions, be it by impurities or through the design through local probing […]

Content review – Lock-in detection

on 15.02.2021 at 15:20 by kivanc on Blog of Kivanç Esat
Test and measurement tasks often carry the challenge that sought for signals are buried in noise. The fundamental use of a lock-in amplifier is to recover these signals, but modern digital lock-in amplifiers can do much more than this. To help you take […]

Automating IQ mixer calibration on the HDIQ

on 03.02.2021 at 22:43 by Chunyan Shi on Blog of Chunyan
As a crucial step in the bring-up of superconducting experiments, IQ mixer calibration normally requires multiple instruments from different parties and manual cabling work. This blog post describes how to use the Zurich Instruments HDIQ, HDAWG and UHFQA (or other […]

Sensing finger movements via impedance measurements

on 19.01.2021 at 12:22 by magda on Blog of Magdalena Marszalek
Smart clothes, wearables and biosensors do not sound as futuristic as they used to. The development in this field of science and engineering is rapid and it is no longer a niche – as seen in the first or even […]

Fast Frequency Sweeps for Impedance Measurements

on 19.01.2021 at 10:59 by Tim Ashworth on Blog of Tim Ashworth
When characterising a device or material as a function of frequency, the resulting spectrum may change with time as the environment or material itself evolves. This time evolution can be captured by taking sequential frequency sweeps with the LabOne Sweeper […]

Compensating Cables for Accurate Impedance Measurements

on 19.01.2021 at 10:45 by Tim Ashworth on Blog of Tim Ashworth
Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly […]

Proximity sensors: inductive or capacitive? Using the MFIA to measure the sensitivity and response time of both sensing regimes

on 07.01.2021 at 17:36 by Meng on Blog of Meng Li
Introduction A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. […]

The Next Generation of Quantum Analyzers: SHFQA Launch Event – Summary and Q&A

on 01.12.2020 at 11:31 by tobias on Blog of Tobias Thiele
On September 1, we launched the second generation of our readout analyzers for superconducting and spin qubits – the SHFQA Quantum Analyzer. Last week on November 17, we dedicated an hour-long event to provide you with the latest insights into […]

Function Generation Via Auxiliary Outputs on Your Instruments

on 26.11.2020 at 17:33 by Meng on Blog of Meng Li
Introduction Quite often one wants to generate an electrical waveform to assist his/her lock-in or impedance measurements. Such a function can be generated by a dedicated function generator, but ideally should be done in the same instrument, not only to […]
