The coupler allows integration to a potentiostat for electrochemical studies. The output signal from the
•
crystal is coupled out by the same network. The signal is then passed through an RMS-to-DC (TRMS)
converter and evaluated by a successive approximation A/D-converter (ADC).
The PLD then performs some low-level math functions and delivers the data to a
•
ground-isolated (ISO), USB interface (USB).
