Abstract: This paper introduces an Electronic Measurement Workstation(EMW) design and implementation based on Virtual Instrument(VI) architecture. It introduces the idea of the Event Processor(EP) and implements it through FPGA. The EMW uses the EP as the control unit of the system, and USB2.0 bus as the communication means between the device and the PC. It integrates several hardware modules, such as oscillograph, logic analyzer, signal generator, etc. The software is developed by using LabWindows/CVI and VC++7.1 based on Windows OS, and it realizes the synchronization and inter-action between related measurement modules.

Key words: Virtual Instrument(VI), Electronic Measurement Workstation(EMW), Event Processor(EP), inter-action
