Interfaces: How to Make or Break a Nanodevice - Q&A


This blog post accompanies the webinar "Interfaces: How to make or break a nanodevice". In this webinar, we discussed the role of interfaces for nanodevices: why they are important, how they can destroy the properties of a nanodevice, and how you can characterize interfaces using different measurement techniques.

DLTS User Meeting 2022 – Q&A


DLTS User Meeting 2022

This blog post presents a selection of questions and answers raised during the DLTS User Meeting 2022. The meeting intended to bring together the community who may face common measurement challenges and allow them to share core competencies and know-how.

Hands-on Electrochemical Impedance Spectroscopy


Hands-on Electrochemical Impedance Spectroscopy

This blog post accompanies the webinar, which introduced basics of electrochemical impedance spectroscopy (EIS) and provided practical tips & tricks to measure EIS consistently. We share the recording, additional information and answers to the questions asked by the attendees during the webinar.

DC-biased Impedance Measurements Using an External Bias Tee


DC-biased impedance measurement

A bias tee is often used in DC-biased impedance measurements. In fact, some impedance analyzers may have a built-in bias tee to allow the output of a sine wave with DC offset. Advanced ones such as the MFIA Impedance Analyzer, are further equipped with an analog adder path to add...

Qubit and Resonator Spectroscopy at the Speed Limit: Your Measurements. Faster.


Qubit Spectroscopy

Getting your measurements up and running as fast as possible is a priority at Zurich Instruments. Together with one of our Application Scientists, researchers at the ETH Zurich - Paul Scherrer Institute (PSI) Quantum Computing Hub were able to install the SHFQC Qubit Controller and perform qubit spectroscopy, Ramsey, and Rabi measurements on 5 qubits in parallel in half a day. The ability of our instruments to perform fast frequency sweeping was at the heart of the fast qubit tune-up procedures. Learn more in this blog post.

Quantum Technology User Meeting 2022 in Munich


Participants of the QT User Meeting

Isn't the best way to learn about experimental methods by exchange with other experts in the field? In this spirit, we hosted the Quantum Technology User Meeting together with Rohde & Schwarz from 13.-15.06.2022 in Munich. If you could not join in person, take a look at this blog post - and stay tuned for the next edition.

Why You Should Use the SHFQC for Few-Qubit Measurements


Two-qubit setup based on SHFQC

It all starts with a few qubits: a masterfully engineered few-qubit system forms the groundwork for advances in large-scale quantum computers. This blog post gives you our 5 top reasons why you should base your few-qubit setup on the Zurich Instruments SHFQC Qubit Controller.

This blog post summarizes the latest academic project of Dino, our new Application Scientist Impedance Analysis. He investigated materials for high-temperature fuel cells in Fukuoka, Japan and the results made it to the front cover of Nature Materials. Learn how light can be used to increase the ionic conductivity of standard electrolyte materials for solid oxide fuel cells, and how to measure this effect using the MFIA Impedance Analyzer.

A Pythonic Approach to LabOne


A Pythonic Approach to LabOne

In this blog post, we intend to shed light on zhinst-toolkit, our all-new high-level Python API. It aims to provide a pythonic approach to interface the test and measurement instruments from Zurich Instruments.

对于一些阻抗测量的应用,诸如传感器表征、电介质材料表征来说,有时需要同时测量两个频率的阻抗值。除了基频之外,另一个频率可能是倍频,也有可能是另一个完全独立的频率。当您的 MFIA 安装 MF-MD 多频选件 之后,就可以完成这一要求,只不过这里的设置与 MFLI 中的 MF-MD 多频选件振荡器频率设置步骤略有不同,这篇博文将予以说明。

Impedance Characterization of a Wideband Bias Tee

A bias tee is often used to add a DC offset to an RF signal ideally without affecting its transmission. In the simplest format, this is often achieved with an L||C circuit, where the high-frequency RF signal passes through the capacitor C, and the DC counterpart is injected across the...




测试测量中常用到任意波形发生器来产生波形和序列,作为系统激励信号。对波形和序列的快速刷新,甚至波形参数的实时调控,是提升测量效率和执行高级调控算法的关键。传统的任意波形发生器在播放波形前,用户需要编译和上传定序程序和逐点定义的全部波形到仪器。当播放的波形很长或者需要频繁更换或重新定序时,需要反复地进行编译和上传,占用很多时间,降低了测试效率。我们的任意波形发生器 HDAWG 的新功能——Command Table 命令表,可以与内置的数字振荡器结合,很好地解决这个问题,仅仅需要少量的波形采样点就可以播放复杂的波形, 并且可以对波形参数进行实时调控。比如,任意波形发生器只需要32个波形采样点(波形单元的最短长度)来产生 Figure 1 和 Figure 2 里的波形序列。

Faster Impedance Measurements at Low Frequency


MFIA Impedance Analyzer

Impedance measurements at frequencies as low as 1 mHz can take a significant amount of time for a multi-point sweep. The MFIA Impedance Analyzer allows for sweeps from 1 mHz to 5 MHz, with a freely selectable number of points up to 100000. In standard mode on the MFIA, a...




经常有用户想了解如何用锁相放大器测量和处理直流信号。常见的需求是对直流信号进行产生和自动扫描,降噪提取,放大输出等操作。因为这属于相对特殊的应用,在进行参数设置时需要注意的地方比较多。在 Jelena 的博文中介绍了用 HF2LI 检测直流信号。在这篇博文中,我将以 MFLI 为例,为大家介绍如何实现这些功能和如何优化参数设置。作为理解参数设置的基础,我们先简要回顾锁相放大器的基本原理。如果想系统学习锁相放大器的原理,可以阅读原理详细介绍, 观看教学视频。
