Frequency Response Measurement with Chirps and Leakage-Free FFT

on 28.10.2016 at 16:08 by brunok on Blog of Bruno Küng
Introduction This post explains how to measure the frequency response of a component or system with high spectral resolution in a minimum amount of time. Rather than sweeping the frequency and recording each spectral point individually, the approach presented here is […]

LabOne Software Trigger as a tool for multichannel mapping applications

on 25.11.2015 at 13:27 by Romain Stomp on Blog of Romain Stomp
In earlier blogs, we presented several methods to synchronize data acquisition with third party instruments, either via the DIO input as a Hardware trigger (TTL pulse), some gated triggering scheme for pass/fail analysis or to capture only transient phenomena in a longer […]

Optimizing PLL Performance with the PID Advisor and Auto Tune

on 27.07.2015 at 13:48 by brunok on Blog of Bruno Küng
Comparison of measured and simulated step response
Introduction LabOne provides two tools that save time and improve performance for anybody working with the UHF-PID controller: The PID Advisor and the Auto Tune feature. They allow automation of the feedback parameter tuning required to achieve the best PID (proportional-integral-derivative) controller performance. In […]

Achieving High Data Transfer Rates with the UHFLI

on 07.07.2015 at 16:42 by brunok on Blog of Bruno Küng
Introduction The UHFLI Lock-in amplifier features the smallest time constant on the market, making it an excellent instrument for fast measurements like in imaging applications. The UHFLI can provide demodulated data at a bandwidth of up to 5.2 MHz and sampled at up […]

Pass/Fail Tests for Failure Analysis

on 08.06.2015 at 16:34 by Romain Stomp on Blog of Romain Stomp
For quality control in manufacturing process, there are many ways to tests for transistors or other component failure, but for high throughput verification usually simple Pass/Fail tests are required. Since devices are tested for various functions, different tests need to be performed […]

Processing Data in Different Applications with LabOne Net Link

on 01.07.2014 at 14:01 by James Wei on Blog of James Wei
Many HF2 and UHF users take advantage of the API provided by Zurich Instruments to program in Matlab, Python, Labview and C to record data from the HF2 and UHF devices. Both HF2 and UHF also provide the possibility to stream […]

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 […]

Ring-Down Method for Rapid Determination of High Q-factor Resonators

on 18.12.2013 at 15:45 by Romain Stomp on Blog of Romain Stomp
With the miniaturization of circuits and components such as MEMS and now also NEMS (Nano-Electro-Mechanical Systems), the variety and quality of macro-fabricated devices have dramatically increased, leading to packaged or embedded systems with particularly sensitive electromechanical properties. The basic properties, […]

GHz Differential Amplifier using a 180° 2-Way Power Splitter

on 10.10.2013 at 15:29 by flavio on Blog of Flavio Heer
Every now and then, a differential amplifier in the frequency range of the UHFLI lock-in amplifier is needed. The requirements for such an amplifier are low noise and a frequency range of at least 600 MHz. A commercial solution with […]
