The design of PMA's hardware and software for one kind of ship navigation radar was investigated. This PMA adopted embedded computer based on PC104 architecture, and integrated COTS products with USB interface, including high precision DMM and broadband oscilloscope. Various signals transformed in the radar system can be tested accurately and easily online.
