摘　　要：测控系统的零点和增益决定了系统的转移函数，一直受到重视。零点的调整比较简单，增益的调整则复杂得多，首先需要一台高精度的信号源作为基准方可实现。本文介绍一种用于增益校准的高精度直流信号源。It is paid attention to that the offset and gain of the measurement and control system decide the transfer function of the system. Adjustment for the offset is very easy, but to adjust the gain is complicated,it must be required a high precision signal sources as a reference sources to implement. This paper describes a high precision DC signal sources used for the gain calibration.
