1.2. Hardware Circuitry
The PARSTAT 4000 circuitry includes:
Two 16-bit digital-to-analog converters (DACs) for versatile waveform generation.
Three 18-bit analog-to-digital converters (ADCs) to measure current (I), potential (E),
SYNC ADC INPUT.
An onboard microprocessor to perform the experiment defined by the operating
software.
Onboard memory to store the programmed parameters and data point values.
The PARSTAT 4000 operates with VersaStudio in either the potentiostatic or
galvanostatic mode, described below.
1.2.1. Potentiostatic mode
In this mode, the PARSTAT 4000 controls the potential at the working-sense electrode
with respect to the reference electrode (see Figure 2). The counter electrode is driven to
the potential required (consistent with the + 48 V compliance of the control amplifier) to
establish the desired working potential. The range over which the working electrode
potential can be controlled is + 10 V.
