The Next Generation of Quantum Analyzers – SHFQA Launch Event


SHFQA Launch Event

On September 1, we launched the second generation of our readout analyzers for superconducting and spin qubits - the SHFQA Quantum Analyzer. On November 17, we dedicated an hour-long event to provide you with the latest insights into the instrument, demonstrate key features and answer your questions. If you missed...

Function Generation Via Auxiliary Outputs on Your Instruments


Function Generation

Introduction Quite often one wants to generate an electrical waveform to assist his or her lock-in or impedance measurements. Such a function can be generated by a dedicated function generator, but ideally should be produced by the same instrument, not only to save lab space but also to minimize the...

Focus on Recovering Signals in Optical Experiments - Q&A


Recovering Signals

This blog post accompanies the webinar “Focus on signal processing in optical experiments". Thank you to everybody who joined the live event and participated actively by voting in the poll and asking so many relevant questions. The answers to all questions are provided at the end of this blog post...

Getting Additional Insights into Your Setup with the MF-DIG Option


DIG Schematics

Lock-in amplifiers are at their best when rejecting the noise and increasing the signal-to-noise ratio. When the setup is well characterized the measurements are carried out at a single frequency and measured against external parameters. Throughout the measurement, detailed noise spectra reveal critical changes in the physics of the experiment...

Boost Your SPM Applications - Q&A


Boost SPM Webinar Screenshot

Following up on the webinar dedicated to Kelvin probe force microscopy (KPFM) techniques, I'd like to post a short summary in this blog as well as answers to most questions raised during this event. The recording of this webinar can be found on the Zurich Instruments YouTube channel here. In...

Inductance of an SMD Shunt Resistor



The reliable and accurate measurement of current is critical to optimising any electronic system. The most commonly used method to measure current flows within a circuit is by using a low-value resistor mounted in series, and then measuring the voltage drop across this resistor. These current sensing resistors are commonly...

The Many Applications of the MF-MD Multi-Demodulator Option


Demodulator Schematic

In my research days, lock-in amplifiers were a standard fixture in a transport measurement setup, and there were many of them. Each lock-in measured one signal in the experiment. Adding more lock-in amplifiers in the setup was the only way to learn more about the device transport properties, but this...

This blog post answers questions asked by the audience during our webinar "Nanoscale light-matter interactions" hosted by Physics Today and featuring guest speakers Markus Raschke and Samuel Johnson. The webinar was recorded and is available on demand here. Here’s a selection of questions asked during the webinar, which we have...

Optimize Signal Acquisition for Optical Measurements - Q&A


Signal Acquisition

This blog post answers the many appreciated questions asked by the audience during the two recent webinar events "Optimize signal acquisition for optical measurements" and "Optimize signal acquisition for optics and photonics measurements". Both events were recorded and are available here and here. Both webinars covered these points: Lock-in amplifier...
