Expanded View of the Series G  Potentiostat

The Series G 300 and Series G 750 Potentiostats consist of two printed circuit boards: a Potentiostat Board and Controller Board.  

The cell cable is connected to the Potentiostat Board (top) directly into the analog electronics of the potentiostatic circuitry.  In operation, about 75% of the Potentiostat Board is covered by a shield to reduce noise pick-up. The four LEDs on the Potentiostat Board indicate cell ON/OFF and diagnostic conditions.

The Controller Board (bottom) is where the digital components of the Potentiostat are located.  These include the DACs for signal generation and Analog-to-Digital Converters for signal measurement.  The Direct Digital Synthesis board for EIS measurement is piggy-backed onto the Controller Board. The input/outputs on the Controller Board include four SMC Connectors (like a BNC, but smaller) for various analog signal.  The 15-pin D connector provides all sorts of analog and digital I/O signals so that the Gamry Potentiostat has all the tools to communicate with the outside world or interconnect with other instruments.
