Sensor Characterization and Control

on 25.05.2020 at 08:00 by kivanc on Blog of Kivanç Esat
Sensors come with different flavors. They can be inertial devices for motion detection; can be based on photosensitive materials; can be absorbing surrounding molecules to detect their concentration, and so on. Developments in micromachining and micro/nanoelectromechanical system (MEMS/NEMS) technologies lead to miniaturization and low power consumption. Hence, multiple sensors […]

Resonance enhancement: a tale of two data analysis methods

on 17.09.2019 at 11:37 by Romain Stomp on Blog of Romain Stomp
The Benefit and Challenge of using 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) […]

How to measure PLL/PID bandwidth under real experimental conditions

on 14.11.2017 at 10:52 by Romain Stomp on Blog of Romain Stomp
With the merging of PLL and PID tab in LabOne for MFLI and UHFLI, the PID Advisor section is now identical for both type of feedback loops and various system models can be tested. After all, a Phase Locked-Loop (PLL) […]

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 […]

HF2PLL for KPFM Applications

on 14.04.2013 at 13:17 by andreas on Blog of Andreas Senn
Kelvin Probe Force Microscopy (KPFM) is a scanning technique that allows the detection of a electrostatic potential distribution of a surface. The HF2PLL supports several variants of KPFM, some of them are mentioned in this post. Amplitude modulated KPFM (AM-KPFM) […]

Using TipProtect to extend AFM tip life expectancy

on 03.12.2012 at 14:51 by andreas on Blog of Andreas Senn
Using a Zurich Instruments Lock-In amplifier, you are enabled to perform a multitude of AFM measurement modes. Particularly interesting is NC-AFM operation which makes use of the built-in PLL capability. Earlier, a user could easily crash his tip into a […]
