摘要
本文研制的微机化阶梯扫描伏安仪，以Ｚ８０微型计算机为核心，由１２位数字信号发生器、恒电位器，１２位数据采集系统以及数据输出线路和逻辑控制电路组成，可提供单扫描和循环扫描的电压。信号允许输入动态范围为±１０伏，最小采样间隔为２毫伏。本仪器具有采样精度高、速度快、数据处理能力强、使用灵活方便等优点。
A microcomputer-based staircase sweep voltamograph has been designed by us, which consists of a Z80 microcomputer, a 12-bit digital signal generator, a potentiostat, a 12-bit data acquistion system, digital output circuits and logic control circuits. It can generate the signal of single sweep and cyclic sweep with linear and staircase voltage. The input dynamic range of the signal is ±10V Sand minimuma cquistion interval is 2 mV. The instrument has many advan- tages such as high data collection accuracy and speed,versatile data processing, and flexible and convenient operation.
