Advanced Basic DC 4 Signal Conditioner

The Advanced Basic DC4 (ABDC4) signal conditioner was designed to provide a clean interface between laboratory hardware and the ACQ-7700 Acquisition Interface Unit.  Instruments such as flow meters, transducers, and gas analyzers provide an analog output with a standard BNC connection.  Capitalizing on this common connector, the simple BNC connectors on the Advanced Basic DC 4 make connection simple, without the need for special interface cables. Since the 7700 series signal conditioners utilize a graphical user interface for configuration, researchers have the capability to save amplifier settings within the software.
