Performing DC I-V Sweeps on the MFIA

10.01.2020

Input Gain and Impedance

Characterizing the impedance of components and materials with the MFIA is done by necessity with an AC signal. However, the MFIA and MFLI can also take DC measurements. This blog post shows how easy it is to take DC measurements, specifically I-V measurements, and highlights a few points to be...

Electrochemical Impedance Spectroscopy of Tap Water

06.01.2020

Nyquist Plot

Electrochemical impedance spectroscopy (EIS) is a popular non-destructive technique to characterize the physicochemical properties of materials, particularly at the solid-liquid (or electrode-electrolyte) interface. Despite the complexity of the measured data, EIS can be used to study many electrochemical devices (batteries, supercapacitors and fuel cells), dielectric coatings, as well as microfluidic chips...

A Deep Dive into Data Acquisition with the DAQ Tool

25.11.2019

DAQ

Looking at the heart of experimental science you will find data acquisition. Why? Because even the most perfectly conceived experiment is worth nothing if nobody acquires, analyzes and stores data for further analysis and reproduction of results. Despite its obvious importance, data acquisition does not always receive the necessary attention...

How to Generate QAM Signaling with the HDAWG

25.11.2019

QAM Signalling

Digital modulation is extensively used in telecommunications, radar systems and quantum technologies. Corresponding to every analog modulation technique, i.e., amplitude modulation (AM), phase modulation (PM) and frequency modulation (FM), there is a digital version of signal modulation...

Bioimpedance of a Muscle Contraction

22.11.2019

Arm with Electrodes

Impedance measurements of biological tissue are commonly used in bio-engineering and life sciences to assess the condition and composition of tissue in a non-invasive, reproducible way. In addition, bio-impedance measurements, also known as bioelectrical impedance analysis (BIA) or electrical impedance myography (EIM), can be used to monitor processes such as...

AWG Precompensation for High-Fidelity CZ Gates in Transmon Qubits

02.11.2019

Noise feature of HDAWG 5V range

High quantum gate fidelity is essential for all quantum hardware platforms. Temporal sensitivity to flux noise and flux pulse distortion can pose major limitations to achieving high fidelity with repeatable two-qubit gates in transmon qubits. In a recent publication, Rol and collaborators demonstrated a fast (40 ns), low-leakage (0.1%), high-fidelity...

Resonance Enhancement - A Tale of Two Data Analysis Methods

17.09.2019

Big Data Big Picture

Benefit and Challenge of Resonance Enhancement Resonance enhancement technique is the fastlane toward raising signal well above the noise floor to increase signal-to-noise ratio (SNR) and dynamical range. Such an approach is common for scanning probe microscopy (SPM) or nano-/micro-electromechanical systems (NEMS/MEMS) that rely on mechanical amplification from a vibrating...

Synchronizing Multiple MFLI Lock-in Amplifiers

16.09.2019

MFLIs rear connection

Multi-channel signal generation and detection are indispensable in many applications such as multi-qubit quantum computing and multi-sensor systems. Synchronization of signal channels comes to the equation when the temporal sequence of events is of interest, especially for fast physical phenomena with short lifetimes...

Are Your Parametric Two-Qubit Gates Limited by the Driving AWG?

13.09.2019

HDAWG Noise Floor

If you are using the Zurich Instruments HDAWG, the answer is no. Let's see why. Parametrically modulated superconducting qubit gates (parametric gates) are usually accomplished by RF-modulation – typically several hundred MHz – of the flux through a mediating coupler element or qubit. Usually, many dBm of signal power are...

Reloading Data into LabOne Modules

29.08.2019

HDF View

LabOne ® now supports reloading data into its modules when using the HDF5 file format. Starting from LabOne 19.05, data acquired in modules such as the Sweeper, DAQ, Scope and Spectrum Analyzer, can be reloaded into the same LabOne module. When the data is loaded into the module, it is...

What is the Basic Accuracy of an Impedance Analyzer?

29.08.2019

Reactance Chart

This blog post explains the meaning of basic accuracy when referring to impedance analyzers. The accuracy of an impedance analyzer is a critical parameter that allows the user to know how close the measured impedance will be to the true impedance of the device or sample under test. As the...

Automated 2D Impedance Sweeps on the MFIA

28.08.2019

MFIA with DUT attached

Many devices and materials exhibit an impedance which depends on both frequency and other parameters such as bias voltage. To fully characterize the impedance of these samples requires an impedance analyzer with the ability to sweep in two dimensions. The MFIA (and MFLI with MF-IA option) can be easily controlled via any of the five included APIs to open up the full parameter space of impedance analysis...

Connecting the MFLI to an External Signal Generator

26.07.2019

The Setup

This blog post describes how to use the MFLI Lock-in Amplifier with an external reference frequency. The reference frequency comes from a signal generator Model 6221 from Keithley which is used to apply higher voltage pulses or sinusoidal signals on the sample. In some situations the MFLI can be used...

Bringing Together the SPM Community in Zurich

SPM Usermeeting Group Picture

"Jamais 2 sans 3" as the French say, where number 3 worked as a charm. We were able to host the third SPM User Meeting in our home city and brought together more users than ever before to share their experiences with Zurich Instruments! Scanning probe microscopy is a broad...
