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. […]

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 […]

Measuring Dielectric Properties of Materials with Varying Thickness

on 30.09.2020 at 08:52 by Meng on Blog of Meng Li
Introduction A dielectric is traditionally defined as an electrical insulator, with very poor conductivity at DC [1]. However, because of its polarizability, charges can be stored in a dielectric material, typically in the format of dipoles, in the low and […]

Inductance of an SMD Shunt Resistor measured with the MFIA

on 15.09.2020 at 10:32 by Tim Ashworth on Blog of Tim Ashworth
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 […]

The many applications of the MF-MD Multi-Demodulator option

on 24.08.2020 at 09:08 by Jelena on Blog of Jelena Trbovic
During 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 […]
