Circuit Board Dynamic Function Testing System
1. Introduction to System Functions
The Universal Functional Tester is a function-testing platform centered around an industrial PC as its control core. It integrates a standard GPIB interface, a multi-channel programmable waveform generator, programmable I/O channels, and a data acquisition module—enabling users to perform maximum flexibility in simulating and testing analog or digital signals from a wide variety of circuits under test. The collected data can then be analyzed qualitatively or quantitatively via the system’s dedicated software.
Additionally, thanks to the GPIB interface, any device compliant with the GPIB standard can be seamlessly integrated into the system, providing virtually limitless scalability. Combined with a flexible and user-friendly human-machine interaction interface, this setup significantly enhances convenience for users during operation.
