Faster Impedance Measurements at Low Frequency

01.03.2022

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...

Discovering the MF-IA Impedance Analyzer Option

11.02.2022

The MF-IA option for the MFLI

This blog post introduces the MF-IA Impedance Analyzer option, which can be added to the MFLI Lock-in Amplifier to enhance it with the same impedance analyzer and precision LCR meter functionality as the MFIA Impedance Analyzer. Adding the MF-IA option to your MFLI gives you the ability to measure the...

How to Set Two Oscillation Frequencies for the MFIA?

09.02.2022

Result of configuring two osc frequencies

Sometimes we want to measure impedance at two different frequencies simultaneously. The second frequency can be either higher-order harmonics or completely independent from the first one. Thanks to the MF-MD Multi-Demodulator option, we can conveniently set this up. In this short blog post, we will walk you through.

How Does a Zurich Instruments Lock-In Amplifier Work?

07.02.2022

General architecture of a Zurich Instruments lock-in amplifier.

Have you ever wondered what is going on inside your Zurich Instruments lock-in amplifier? Lock-in amplifiers enable precise measurements of small signals buried in noise. While analog instruments have been used for decades, the development of analog-to-digital converters with high speed, resolution, and linearity has more recently enabled the realization...

Best Practices in Sensor Characterization and Control - Q&A

02.12.2021

Bode plot of the resonance of a sensor

For this webinar we teamed up with Dr. Tomás Manzaneque , whose work focuses on the fabrication, modeling and interfacing of mechanical micro-resonators in different fields of application: examples are rheological sensing, ultra-sensitive mass sensing, passive conditioning of RF signals for the Internet-of-Things communications, and single-cell biopsy. His research interests...

Un'architettura LabVIEW per costruire sistemi DLTS con lo MFIA

23.09.2021

MFIA configuration

Questo blog post descrive un codice basato su LabVIEW™ per utilizzare l'analizzatore di impedenza MFIA per effetturare misure di spettroscopia transitoria di livello profondo (DLTS), compreso un template per aggiungere il controllo di un termoregolatore di terze parti. La DLTS è una tecnica potente e comunemente usata per studiare la...

Efficient Generation of Dynamic Pulses

08.09.2021

Rabi Cyclic

Solid-state qubits are typically characterized and operated by a series of very short pulses. To achieve a high-fidelity control, it is necessary to generate many sequences of them, with very accurate timing. In this blog post, I will show how to use the advanced feature set of the HDAWG Arbitrary...

The LabOne Multi-Device Synchronization Feature

24.08.2021

Configuration to measure the Hall effect using 2 MFLI Lock-in Amplifiers synchronized with MDS.

In this blog post we want to present a lesser known but very powerful LabOne ® tool freely available to all Zurich Instruments users: multi-device synchronization (MDS). Although all Zurich Instruments lock-ins and impedance analyzers are equipped with multiple demodulators either natively or through upgrade options, and most instruments have...

Impedance Characterization of Wearable Capacitive Sensors

18.08.2021

Histogram

This blog post explains how the Zurich Instruments MFIA can be used to characterise wearable capacitive sensors, and introduces two recently published studies where innovative flexible wearable sensors have been developed which operate on the principle of capacitive sensing. These studies present different approaches to comfortable-to-wear sensors with sensing performance...
