Abstract

Diversification and complication of circuit units of modern radar bring requirement of more functions for signal source used for test. Based on virtual instrument, microprocessor, DDS, CPLD and circuit share technologies, a portable integrated signal source for circuit unit test of radar is developed, which integrates DC power supplies, AC power supplies, low frequency signal source, intermediate frequency signal source and digital signal source into one instrument. The composition of the hardware and the software of the integrated signal source and their design principles are given in the paper. Testing results show that the integrated signal source provides a good test platform for circuit units of radar.
