Design of vector signal generator RF dynamic switching system

The current RF dynamic switching system of the vector signal generator proposed is too long and the power loss is high. In order to solve the above problems, the vector signal generator RF dynamic switching system is designed based on time division multiplexing(TDM) technology. The AV1443 vector signal generator is used as the vector signal generator. During the design process, the application program sends the chip to convert the vector signal Information is processed in a unified manner, and data output and input ports with information conversion are designed. The dynamic calculation of the radio frequency state is performed in a multi-channel environment. The discrete fourier algorithm is used to express and analyze the radio frequency dynamics of the vector signal. The experimental results show that the TDM-based vector signal generator RF dynamic switching system can shorten the switching time and reduce the power loss. The switching time of the system in this paper is 0.02 s shorter than that of the traditional system under the same working frequency, and the power consumption of the system after completing the whole switching task is always controlled within 1 W.
