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 […]

A deep dive into data acquisition with the DAQ tool

on 25.11.2019 at 14:21 by moritz on Blog of Moritz Kirste
Introduction Looking at the heart of experimental science you will find data acquisition. Why? Because even the most perfectly conceived experiment is worth nothing if nobody acquires, analyzes and stores data for further analysis and reproduction of results. Despite its […]

Frequency-Domain Response of Lock-in Filters

on 19.03.2019 at 18:10 by Mehdi on Blog of Mehdi Alem
Introduction  The response of a lock-in amplifier is characterized by the parameters of its low-pass filter (LPF), i.e. time constant and filter order. The temporal response of the LPF demonstrates the latency of measurement while its spectral response shows the […]

Enhancing the Luminosity Quality of Sulfur Plasma Lamps by the HF2PLL Phase-Locked Loop

on 07.12.2017 at 14:11 by Mehdi on Blog of Mehdi Alem
Introduction The choice of technology in lighting industry requires a trade-off between color rendering and luminous efficacy because the spectral sensitivity of the human eye varies with wavelength. As sustainable development has become a priority, the manufacturing industry of lighting […]

Noise Analysis of Signal Components

on 29.03.2017 at 13:57 by Mehdi on Blog of Mehdi Alem
Introduction  In this post, the relation between the noise of signal amplitude and phase on one hand and the noise of in-phase and quadrature components of the signal on the other hand is investigated. We try to respond to the wrong […]

LabOne for HF2: using digital lines as trigger sources

on 03.02.2016 at 11:39 by Romain Stomp on Blog of Romain Stomp
Since LabOne 15.11 release and onward, accessible from our download area, all HF2LI users with the enabled HF2LI-WEB option can now benefit from the latest software developments that were previously reserved for the UHFLI. One tool that is now totally new for this […]

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 […]

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 […]
