Design of a Multi-function Signal Source System

In order to solve the problem that the single signal source can not meet the requirement of the test, a new design scheme of multi - function signal source system is put forward. The hardware and software design of the signal source system are described in detail, the scheme is based on the consideration of three aspects of standardization, high speed and reliability, the hardware environment is based on PCI Compact industrial control computer, the signal source board of CPCI 3U structure is designed, and supporting software to adopt modular design. The scheme can realize the independent output and simultaneous output of the multi type, multi channel high precision and high reliability signals. The experimental results show that the system has good stability, high reliability and convenient use, and can meet the design requirements.
