Pseudo-random number generator in the run time of AWGs

on 08.11.2019 at 14:34 by claudius on Blog of Claudius Riek
This post discusses ways to generate noise signals within a well-defined frequency range, amplitude, defined distribution (white, Gaussian, etc.), and minimal correlation using Arbitrary Waveform Generators (AWG). Sample-by-sample programming of the waveform leads to very well-defined properties, but the signal […]

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 […]

LabOne Imaging: Software Trigger’s new Grid Mode

on 27.09.2016 at 11:32 by Daniel on Blog of Daniel Wright
An image obtained using SW Trigger's Grid Mode.
In LabOne Release 16.04 the Software Trigger receives a powerful extension, Grid Mode, which organises the triggered data in a 2-D matrix allowing image construction direct from LabOne. This blog explains how this new functionality works and describes its most […]

Working with LabOne Software Trigger Data in Matlab

on 18.04.2016 at 10:42 by Daniel on Blog of Daniel Wright
LabOne’s Software (SW) Trigger allows the user to save bursts of instrument signals (e.g. its demodulator samples or a PID controller’s error value) when a specified trigger condition is met. The SW Trigger works much in the same way as […]

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 […]

Using HF2IS Impedance Spectroscope for FRA, 2-Terminal and 4-Terminal Measurements

on 19.09.2013 at 14:14 by James Wei on Blog of James Wei
Often there are questions from our HF2IS Impedance Spectroscope users on how to configure the HF2IS for frequency response analysis (FRA), 2-Terminal impedance measurement, or 4-Terminal impedance measurement. This short blog will clarify the proper physical connections as well as […]

ω/2 Demodulation for a Parametric Oscillator

on 27.02.2013 at 10:04 by James Wei on Blog of James Wei
We often get questions from HF2LI lock-in amplifier customers who characterize MEMS and sometimes from those doing AFM scans on how to measure at half reference frequency using a lock-in amplifier. Half reference frequency lock-in measurement is often necessary when […]

Generate Cole-Cole impedance plot using HF2IS Impedance Spectroscope

on 11.12.2012 at 08:36 by James Wei on Blog of James Wei
In the version of ziControl prior  to 12.08, our HF2IS Impedance Spectroscope customers could only observe the impedance measured through post-processing: one had to save the measurement X, Y data onto the PC, calculate the voltage and current quantity and […]
