In order to communicate between terminal devices and avionics which are connected with 1553B bus during satellite pay-load testing field, communication board from 1553B to standard peripherals interface is needed. In this paper, through studying 1553B bus and PCI bus protocol, one conversation technology between 1553B and PCI bus in space-ground testing filed is present-ed. The paper put forward hardware diagram, partial principle and interface FPGA realization. Through test, the board can realize communication between remote terminal device and computer with PCI bus and has been used in XXX satellite ground testing filed.
