| Abstract: | In order to overcome the shortage of the traditional calibration method, to simplify the panel design and calibration process of automated test equipments, a program-controlled multiplexed channel switch circuit with wide range input voltage is de-signed based on single-chip microcomputer technology and RS-422 communication interface. Working principle of circuit, choice of components, hardware and software design process are introduced. The circuit has been applied to some test equipments, and runs normally. |
