Resolution, Scanning Speed and Demodulation Bandwidth

on 06.12.2011 at 09:40 by Andrin
This post is about the interplay between resolution, scanning speed and demodulation bandwidth. I demonstrate how the scanning process can be described in spatial, time and frequency domain, and show that this is a valuable toolbox to analyze your measurement setup as a whole.

Exploring the HF2LI-MOD: Measuring Bessel Functions

on 20.10.2011 at 12:40 by Andrin
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
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.

Controlling Zurich Instruments Devices with LabVIEW

on 06.09.2011 at 14:56 by Andrin
With Zurich Instruments LabVIEW driver, you can integrate your device into complex laboratory setups and create your own graphical interface for simplified experiment control.The driver provides access to all adjustable parameters and measurement readings of your Instrument.
In this post, I explain on the VIs included in our LabVIEW driver and on a simple example on parameter setup and data streaming. LabVIEW beginners find a link to our Getting Started for guaranteed programming success in LabVIEW.
