What it Takes for High-Speed AFM Measurements

on 19.02.2014 at 14:06 by Romain Stomp on Blog of Romain Stomp
Typically for biological and catalysis applications, time matters! And AFM images that record in 10 minutes or more are not acceptable. We often receive inquiries about what constitutes a complete solution for ‘fast AFM’ and what Zurich Instruments can offer […]

Taking Your Microfluidics EIS Measurement to the Ultra-High Frequency Domain

on 08.01.2014 at 13:28 by James Wei on Blog of James Wei
Introduction The HF2IS Impedance Spectroscope from Zurich Instruments is a versatile tool suitable for label-free electrical impedance spectroscopy (EIS) of single cells in the domain of cell counting and discrimination. The high frequency range, from DC to 50 MHz, and the […]

Meanwhile I have helped so many people working with lock-in amplifiers with a handful of generally applicable Tricks, that I’d like to share them in a compact compilation. Certainly they apply to the Zurich Instruments HF2LI Lock-in Amplifier and to […]

Double-sideband Suppressed-carrier Modulation

on 28.08.2013 at 11:17 by Sadik on Blog of Sadik Hafizovic
Double-sideband Suppressed-carrier (DSB-SC) modulation is an amplitude modulation, which consists only of the two symmetrical sidebands and no carrier band. I came across this scheme in an ultra-sound application, where the power utilization can be maximized when all power is […]

Broadcasting FM and AM Radio with the Zurich Instruments UHFLI 600 MHz Lock-in Amplifier

on 06.05.2013 at 17:19 by Sadik on Blog of Sadik Hafizovic
Following my previous blog, Listening to FM Radio with the UHFLI 600 MHz Lock-in Amplifier and PLL, people advised me to also try and broadcast FM Radio. Naturally for this I had to retreat into Zurich Instruments’ shielded radiation lab, […]

Listening to FM Radio with the UHFLI 600 MHz Lock-in Amplifier and PLL

on 17.04.2013 at 11:10 by Sadik on Blog of Sadik Hafizovic
A guy at Zurich Instruments soldered a 3.5mm headphone socket to a BNC cable and attached a 75-cm antenna wire to the Signal Input of our 600MHz UHFLI Lock-in Amplifier with UHF-PID PID/PLL option and was happily listening to FM […]
