Content review – Lock-in detection

on 15.02.2021 at 15:20 by kivanc on Blog of Kivanç Esat
Test and measurement tasks often carry the challenge that sought for signals are buried in noise. The fundamental use of a lock-in amplifier is to recover these signals, but modern digital lock-in amplifiers can do much more than this. To help you take […]

Automating IQ mixer calibration on the HDIQ

on 03.02.2021 at 22:43 by Chunyan Shi on Blog of Chunyan
As a crucial step in the bring-up of superconducting experiments, IQ mixer calibration normally requires multiple instruments from different parties and manual cabling work. This blog post describes how to use the Zurich Instruments HDIQ, HDAWG and UHFQA (or other […]

Sensing finger movements via impedance measurements

on 19.01.2021 at 12:22 by magda on Blog of Magdalena Marszalek
Smart clothes, wearables and biosensors do not sound as futuristic as they used to. The development in this field of science and engineering is rapid and it is no longer a niche – as seen in the first or even […]

Fast Frequency Sweeps for Impedance Measurements

on 19.01.2021 at 10:59 by Tim Ashworth on Blog of Tim Ashworth
When characterising a device or material as a function of frequency, the resulting spectrum may change with time as the environment or material itself evolves. This time evolution can be captured by taking sequential frequency sweeps with the LabOne Sweeper […]

Compensating Cables for Accurate Impedance Measurements

on 19.01.2021 at 10:45 by Tim Ashworth on Blog of Tim Ashworth
Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly […]

Proximity sensors: inductive or capacitive? Using the MFIA to measure the sensitivity and response time of both sensing regimes

on 07.01.2021 at 17:36 by Meng on Blog of Meng Li
Introduction A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. […]

The Next Generation of Quantum Analyzers: SHFQA Launch Event – Summary and Q&A

on 01.12.2020 at 11:31 by tobias on Blog of Tobias Thiele
On September 1, we launched the second generation of our readout analyzers for superconducting and spin qubits – the SHFQA Quantum Analyzer. Last week on November 17, we dedicated an hour-long event to provide you with the latest insights into […]

Function Generation Via Auxiliary Outputs on Your Instruments

on 26.11.2020 at 17:33 by Meng on Blog of Meng Li
Introduction Quite often one wants to generate an electrical waveform to assist his/her lock-in or impedance measurements. Such a function can be generated by a dedicated function generator, but ideally should be done in the same instrument, not only to […]

Get additional insights into your setup with the MF-DIG option

on 08.11.2020 at 15:50 by Jelena on Blog of Jelena Trbovic
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 […]

How to Retrieve the Carrier Frequency of Phase-Modulated or Carrier-Suppressed Signals with Costas Loops

on 08.11.2020 at 13:43 by Mehdi on Blog of Mehdi Alem
Introduction  Phase-locked loops (PLLs) are widely used to recover the frequency of a carrier signal in many detection systems such as lock-in amplifiers and data receivers. In order to properly lock to the carrier phase and extract its frequency, a […]
