| Abstract: | It is hard to produce microwave measurement instrument in batches because of distributed parameters.To facilitate maintenance and manufacture of microwave measurement instrument,this paper brings forward PnP(plug and play)technology including circuit unit and software protocol.The circuit unit is realized by I2C bus which mean simple structure and easy to use.I2C bus controller is designed by CPLD and can be used either in ISA bus or PCI bus system and have no EMI interference to microwave measurement instrument.The software protocol can be used in all operation systems including Microsoft Windows.By this technology the application software of microwave instrument can identify all function boards of instrument,then configure it automatically and load software function component for it.No need to debug the function board again when the microwave instrument is put into production.This technology is used in highly sensitive broadband EMI Test Receiver successfully. |
