| Abstract: | In order to structure the RF power auto-calibration system and improve the efficiency of RF power calibration and measure. The author design a kind of interface card circuit using NAT9914. The implement method of software is discussed and the flow chart of software design is given. This interface card has been successfully used in RF power auto-calibration system and the basic function of GPIB has been already implemented. And it is helpful for engineering technicians. |
