Capturing transients with Zurich Instruments Toolkit: Programing your instruments was never that easy

on 07.04.2021 at 09:27 by Meng on Blog of Meng Li
In many applications, Zurich Instruments lock-in amplifiers and impedance analyzers are integrated into a larger measurement system. Having an application programable interface (API) to obtain necessary information from the instruments is of great importance in such cases. Thanks to the […]

Sensing finger movements via impedance measurements

on 19.01.2021 at 12:22 by magda on Blog of Magdalena Marszalek
Smart clothes, wearables and biosensors do not sound as futuristic as they used to. The development in this field of science and engineering is rapid and it is no longer a niche – as seen in the first or even […]

Dynamic suppression of unwanted frequency components with an HF2LI

on 26.06.2015 at 14:17 by Paolo Navaretti on Blog of Paolo Navaretti
There are many experimental situations in which the component of interest in a signal is not the strongest one, but some other related component, for instance the side bands in amplitude or frequency modulated signals. In such a case, the […]

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 […]

Exploring the HF2LI-MOD: Measuring Bessel Functions

on 20.10.2011 at 12:40 by Andrin on Blog of Andrin Doll
In this post, I demonstrate the capabilities of the HF2LI-MOD upgrade by demodulating 4 FM sidebands simultaneously. With the help of a basic sweep routine programmed in LabVIEW, I measure 5 Bessel functions by direct sideband demodulation of an FM signal. This post might give you an inspiration on how to improve your measurement sensitivity by introducing an advanced demodulation scheme of multiple sidebands.

Pseudoheterodyne Detection in Optics

on 15.09.2011 at 15:56 by Andrin on Blog of Andrin Doll
There is a new application note about pseudoheterodyne detection in nearfield optics. The application has also relevance for laser spectroscopy. Hereafter are a few personal comments about phase sensitive detection in optics, as I participated in the described experiments.
