A Portable Pulse Signal Generator for Photoelectric Detection System

This paper presents the design of a simple portable large pulse signal generator, which is used to drive high-brightness LED luminescence and provide analog strong light source for photoelectric detector, so as to check the working state of system in pulse radiation measurement. This design is based on programmable CPLD device and two-stage drive circuit to generate single pulse signal with adjustable pulse width and amplitude manually. The prototype with the advantages of small volume, light weight, large output signal amplitude and low cost, which has been successfully applied in strong pulse radiation measurement for large-scale equipment such as accelerator.
