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 […]

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 […]

Using Vertical Axis Groups to plot signals of different scales or units

on 13.10.2014 at 10:52 by Paolo Navaretti on Blog of Paolo Navaretti
LabOne offers a flexible display of multiple signal waves within the same plot. This blog describes the functionality of the vertical axis groups which allow a fine control on how signals are bound together within the plot. Vertical Axis groups […]

Loading data saved from the LabOne UI in Python

on 05.08.2014 at 17:07 by Daniel on Blog of Daniel Wright
Demodulator R signal with threshold.
The LabOne User Interface can continuously save instrument data such as demodulator samples to hard disk as binary data in MAT (Matlab®) files or as plain text in CSV (comma separated value) files. Using MAT files, demodulator data can be recorded at full […]

Basic vector network analyzer (VNA) measurements using the UHFLI

on 03.07.2014 at 15:43 by dragan on Blog of Dragan Lesic
Introduction This article describes how to measure reflection and transmission coefficients using a Zurich Instruments UHFLI Lock-in Amplifier and a directional coupler. Network analysis is a commonly performed in RF measurement. A network analyzer is an instrument that measures the network […]

Sideband Analysis with Lock-in Amplifiers

on 27.02.2014 at 20:10 by Sadik on Blog of Sadik Hafizovic
When a sinusoidal waveform is periodically modulated in either amplitude or frequency sidebands are generated as a result of this carrier modulation. These sidebands can be measured using a lock-in amplifier. Zurich Instruments lock-in amplifiers (HF2LI and UHFLI) can measure […]

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 […]
