Subsampling Techniques for Achieving Waveform Precision in Picoseconds


An arbitrary waveform generator (AWG) can generate pulses with a timing resolution much finer than its sampling period. Users are often unaware of this capability, yet it enables highly precise timing control in application use cases such as NV center dynamical decoupling, flux pulse width control, AWG channel deskew, and IQ mixer calibration...

Mass Sensing – An Overview


Among sensing applications, mass measurements have received a lot of attention with the shrinking of devices and the ability to detect individual particles. We have witnessed the shift from macroscopic devices such as the micro-balance to micrometer-size resonator devices and, now, to 2D or 1D materials with exquisite resolution down to a single proton's mass...

Electrochemical Impedance Spectroscopy Beyond 300 GΩ


MFIA Impedance Analyzer

In electrochemistry, the characteristics of a given process can be assessed by electrochemical impedance spectroscopy (EIS). A semicircle in the Nyquist plot usually corresponds to electrochemical processes that can be modelled as a parallel connection of a resistor (R) and a capacitor (C). The diameter of the semicircle provides the value of R, while the associated time constant (also known as relaxation time) is given by RC...

Impedance Measurements on Grounded Components


Setup for measuring grounded components with the MFIA

The MFIA is a high-precision impedance analyzer. It measures voltage, current and phase to calculate impedance. As is the case for most impedance analyzers, the measurement circuit is designed so that the device under test (DUT) is operated under floating conditions, which means that none of the terminals of the DUT is connected to the ground...

Dielectric Impedance Measurements of Chocolates

Swiss chocolates are famous worldwide thanks to their high quality of taste. Switzerland is also renowned as the country with the highest chocolate consumption per capita. Today, many popular brands can be found even in the supermarket. Are you curious about what makes the chocolates special? And which non-destructive technique (NDT) can be employed to measure them?

Hands-on Superconducting Qubit Characterization


This blog post accompanies the webinar "Superconducting Qubit Characterization", which introduced the basic physics of transmon qubits as well as the tools and methods required to tune them up. The webinar included a live Q&A session, but due to time constraints, not all of the viewers' questions could be answered within the duration of the session. Below, we address the technical questions asked during the webinar...

Synchronizing Multiple AWG Channels


Pulse sheet

Does your application require multiple AWG channels with precise and stable timing synchronization? In this blog post, we will show how to achieve this with the HDAWG Arbitrary Waveform Generator for setup sizes ranging from few channels up to 144. We demonstrate 3 methods suitable for different use cases.

Understanding the Sweep Duration in the LabOne Sweeper Module

A fast sweep capability is often desired by researchers working on fast physical phenomena or short-lived samples, and may also be beneficial purely from a time-saving perspective. This blog post will elucidate the factors on which the sweep rate depends and guide you along several possible ways to make the...

How to Choose the Optimal Demodulator Data Transfer Rate


Setting the data transfer rate in the UHFLI Lock-in Amplifier

The most beautiful measurement data is useless if it cannot be saved and analyzed. Choosing the data transfer rate from the instrument to the host computer wisely is important to capture the information of interest and avoid measurement artifacts. In this blog post, we will look at the data transfer concept of a Zurich Instruments lock-in amplifier in more detail and provide guidelines on how to choose it.
