“源”为电压源和电流源,“表”为测量表,“源表”即指一种可作为四象限的电压源或电流源提供精确的电压或电流,同时可同步测量电流值或电压值的测量仪表;源表突出特点:使用一台仪器进行多种测量 ;数字源表是电学测试的必备仪器之一,是一种多用途仪器、特别适合现代半导体、纳米器件和材料、有机半导体、太阳能电池、印刷电子技术等领域;


数字源表功能:

①集合电压源、电流源、电压表、电流表、电子负载的功能于一身,广泛用于各类精密器件的测量。

②支持四象限工作,可作为源或负载

数字源表优点:

同时精确提供和测量电压和/或电流;

      同步测量,减少测试时间


提供和测量非常广的电流和电压;

      电压测试范围30uV-300V,电流测试范围1pA-1A


支持运行用户脚本程序,无需电脑控制,提高生产测试速度;

      序列测试,简化操作,降低成本


采用用户熟悉的图形界面,不管用户经验是否丰富,使用起来都非常简便;

      触屏操作


 

与传统电源比:

电源过零需要改变线连接方式;

       增加需反复开关机械开关,降低了设备可靠性


电压电流限制精度有限;

       电压1%,电流10mA


与电源结合万用表组合比:

万用表电源组合需要编程实现设备控制及同步;

       复杂连线、编程开发


电源限压限流性能差

       限压限流精度低,瞬态特性也无法保证
