UPC-32 Instrument Sequence Control Based on LabVIEW

The unit UPC-32 supplied by PACIPIC company, is a programmable three-phase power supply control which is used for the alternating current power supply of AMX series products. In the application of performance test for an electronic product, it is achieved the performance data via analysis meter PZ4000, that is used for the object test and analysis in dif This article introduces a sequence control method of unit UPC-32 based on the Lab VIEW software. It is by means of GPIB interface bus to realize the communication between PC machine and programmable power control unit UPC-32. In this application, the power control is taken by a unit UPC-32 through its driver programming . In this programming, to make the software reusability is a purpose design, which is used with sub drive VI to improve the software application. The design also improves the testing automation, testing efficiency and accuracy, being easy to extending.
