DATA PHYSICS 'MOBILIZER II' Spectrum analyser
State of the art spectrum analyser used for single- and multi-shaker modal testing of structures. 32 input channels and 4 output channels with 24-bit resolution. The Mobilizer chassis connects to a laptop PC via Ethernet and runs SignalCalc software that interfaces with a range of modal analysis packages.

DATA PHYSICS 'QUATTRO' Spectrum analyser
State of the art spectrum analyser used for single- and dual-shaker modal testing of structures. 4 input channels and 2 output channels with 24-bit resolution. The Quattro analyser connects to a laptop PC via Ethernet and runs SignalCalc software that interfaces with a rannge of modal analysis packages.

NATIONAL INSTRUMENTS ‘COMPACT DAQ’
NI-USB 9233, NI USB-9234 and NI USB-9239 24-bit 4-channel data acquisition systems, with automatic anti-alias filtering, driving IEPE and Voltage-output accelerometers. LabVIEWirtual instruments (VIs) developed for continuous data acquisition and interfacing with modal analysis software.

GEOSIG GSR-24 Seismic recorder
This functions as a battery-powered stand-alone 24 bit data acquisition system with scheduling and GPS synchronisation. These recorders were used with units from FEUP to for measurements on the Humber Bridge in 2008. Seen here connected to a set of three QA-700 accelerometers.

Bespoke remote data acquisition systems such as the one shown here, have been created for monitoring of football stadia, chimneys, bridges and buildings, using robust, high quality acquisition and computing hardware.
