Abstract:Focusing on the difficult problems of manual calibration of coaxial attenuators, such as long time and prone to human errors in the calibration process, through research on automatic calibration methods for attenuators, research and development of variable attenuator program control devices, research on the control principles of standard equipment such as measurement receivers, network analyzers, signal generators, and the use of bus control technology, VS is used to design a set of attenuator attenuation, initial attenuation Automatic testing software for projects such as voltage standing wave ratio, and the establishment of an automatic attenuator calibration platform to achieve rapid attenuator calibration. After verification, the calibration platform operates stably, with accurate and reliable data, greatly improving the attenuator detection efficiency.
