New opportunities with the open architecture test system

The general view of the Open Architecture test system is shown in Figure 1. It is a distributed object environment under Microsoft Windows operating system. The test system itself has been defined as a modularized system with a module control software and a backplane communication library. The definition of modules includes digital modules, device power-supply (DPS) module, arbitrary waveform generator (AWG) module, digitizer module etc. An open backplane communication library accessed via C++ language based test program and a GUI test programming layer above C++ provides a generalized user??s interface for the test system.
