| Abstract: | Microcomputers have been widely used in circuit test. In order to automatize the testing and improve test speed,efforts have to be made on the development of the interface to microcomputers and on its applications. The implementation of automatic test of DAC' s using microcomputers is dealt with in the paper. Also described are the development of test-specific interface and its application.i. e. bus extension for microcomputers,isolation of microcomputers from test, programmable power supply .relay matrices and 8-16 bit data channels etc. |
