The DBA8000 is a compact state-of-the-art Digital Bridge Amplifier. It is built to the latest standards in digital and analogue technology. WPI’s Digital Bridge Amplifier (DBA8000) has 8 identical channels that can be configured and calibrated independently and used as a Full Bridge Amplifier, Half Bridge Amplifier or as a Differential Amplifier (DC coupled). In any of these modes, analogue input signals are converted in real-time into digital values (24-bit resolution) and processed by a Digital Signal Processor (DSP) microcontroller. Real-time digital signals are then converted in to analogue signals that can be measured from the BNC output sockets. This same digital data are also made available at the Ethernet port or displayed on the LCD in a resolution up to five significant figures.

In the bridge amplifier mode, eight digital signal synthesizers generate the excitation amplitudes (with the desired phase and frequency) for the bridges. All parameter settings can be stored in up to 10 different parameter memories to ensure quick installation and start-up. The DBA8000 is fully menu driven using the touch screen LCD that displays menus and enables the operator to select or enter data. A password protected hierarchical structure limits the privileges for users and owners; the administrator always has full control over all parameters of the DBA8000. The Digital Bridge Amplifier’s programmed software parameters and, or, memories can be exported to (or imported from) an FTP server for easy updates. The DBA8000 is fully compatible with most brands of biomedical transducers and is pre-configured for WPI’s popular FORT force transducers. What makes this amplifier so unique is that measurements from experimental subjects can be displayed in the standard units (such as mmHg, mmO₂, mV, KPa) or any other units that can be programmed with defined parameters. Indeed the DBA8000 is the new workhorse of Bridge Amplifiers!
