The University of Ghent bought an HBM GEN5i for the project. According to Frederik Allaeys, this data acquisition system was chosen in particular because of its modular structure, which allows cards for different applications to be added easily. The GEN5i is a complete, portable data acquisition system that has been specially developed for high-speed data acquisition with sampling rates of up to 100 megasamples per second. It can be expanded to a maximum of 160 simultaneous measurement channels, and is therefore suitable for complex measuring set-ups. The laboratory in Ghent uses an average of ten to fifteen channels and sampling rates of up to 25 MS/s.
The GEN5i data recorder is a complete computer containing an integral hard disk for storing data. This data can be sent for further analysis via standard interfaces such as WLAN, Gigabit Ethernet or USB. In addition, the standard configuration of the recorder includes various filters, as well as HBM’s Perception software for the processing, analysis and visualisation on the screen of an enormous amount of measurement data. The GEN5i is a transient recorder, which records extremely fast and one-off signals. This type of signal is often characteristic of destructive material tests, fire tests and high voltage. The recorder can be configured and started quickly, thanks to its simple user interface and proprietary software.
