This new bus standard applications in the United States, the Chinese munity are very much appreciated, numerous researchers. And after years of exploration, the country has made great progress in the implementation of certain aspects of the specific application, especially in the application of many military radar systems.D. Millimeter wave electronic test equipment to advance Numerous civilian and military electronic equipment in the millimeterwave development, particularly in the military field, and its development more rapidly. AdvanceTaking into account the future of electronic warfare systems signal environment will reach 12 million pulses / sec, equipment systems may want to perform several one hundred million , the current IC processing power can not meet the requirements of military electronic equipment, which will affect the next generation of electronic warfare systems operational capability, this must be the development of ultrahighspeed integrated circuits (VHSIC). So from a monolithic integrated circuit chip set test into several one hundred thousand to one million across several, which correspondingly substantial increase in the difficulty of the test.Ⅲ. Electronic Measurement Technology TrendsA. Networking and modulars Software Instrument (Softwareisinstrument) pletely broke the traditional instruments can only be given by the manufacturer the user can not change the situation.C.
