Absolute Time Recovery using Agilent TDC

Abtract: This document describes the methodology to utilize the Agilent (Acqiris) U1051A Time to Digital Converter (TDC) module in applications requiring absolute time measurements beyond the range of the module. The TDC module is a precise event counter with 50 ps timing precision.

Fusion via Tokamak

In this paper published in the volume 80 of the Review of Scientific Instruments (73222996) in October 2009, you will learn about fusion experiment through a Tokamak  device. After testing, the authors acknowledge that it’s one of our Agilent cPCI digitizer that is the best solution to support this experiment requirements.

ADC cards in mass spectrometer for planetary space research

We have just discovered that the first 2013 issue of the Journal of Mass Spectrometry Volume 48, Issue 1, published by John Wiley & Sons, Ltd. features an article from Riedo, A., Bieler, A., Neuland, M., Tulej, M. and Wurz, P. (2013), Performance evaluation of a miniature laser ablation time-of-flight mass spectrometer designed for in situ investigations in planetary space research. J. Mass Spectrom., 48: 1–15. doi: 10.1002/jms.3104. These researchers work at the Institute of Physics at the university of Bern. They explain in the article how they develop a miniature mass spectrometer that could be used in future space mission to analyze the chemical composition of planetary surfaces, their moons, asteroids and comets.  They relied on 2 Agilent high-speed ADC cards to do the data acquisition and processing: the U1084A and U1082A check how in the article. 

High-speed ADC with FPGA used as a FFT spectrometer

This article was published jointly by the ETHZ Department of Astronomy and the Institute of Applied Physics at University of Bern who tested the relevance of using a Fast Fourier Transform (FFT) spectrometer to measure trace gases such as ozone and water vapor in the atmosphere in real time. As we are facing more and more issues with global warming and ozone depletion. This article  introduces a new technology that is maybe today used more largely. In any cases the ADC  board used in this case was one of the first digitizer with on-board processing developed by our team.

Müller, Axel Murk, Christian Monstein,  Niklaus  Kämpfe, Hansueli Meyer

Why averagers rock?

The graph speaks for itself. Our latest 8-bit 4Gs/s data converter which can be ordered with an averager FDK option definitely shows a better SNR in comparison to his older counterpart the U1082A and U1081A. 

Wideband on-board processing digitizer in HPTRF instrument

Today, we have the pleasure to share with you an article published in the Review of Scientific Instruments, vol. 81, 103101 (2010) by Joseph M. Muretta, Alexander Kyrychenko, Alexey S. Ladokhin, David J. Kast, Gregory D. Gillispie, and David D. Thomas. This paper was sent to us by one of our business development engineer based in United States, William Accola. The authors describe a high-performance time-resolved fluorescence (HPTRF) spectrometer that dramatically increases the rate at which precise and accurate subnanosecond-resolved fluorescence emission waveforms can be acquired in response to pulsed excitation. You will see the article that these performances have been achieved using a 10-bit 8 GS/s digitizer. Which one is it? The first one to guess will get a T-shirt. Now check the article and learn about the advantages to use such a digitizer:
