Digital radio frequency memory board

Abstract

The invention provides a digital radio frequency memory board. An analog / digital converter module for the digital radio frequency memory board is used for acquiring an external analog signal at a high speed, converting the external analog signal into a digital signal and transmitting the digital signal to a first field programmable gate array (FPGA) module, wherein the first FPGA module is used for performing primary programmable processing on the digital signal and transmitting the digital signal to a second FPGA module; the second FPGA module is used for performing secondary programmable processing on data and finally transmitting the data to a digital / analog converter module; the digital / analog converter module is used for converting the digital signal into an analog signal at a high speed and outputting the analog signal; a first static random access memory (SRAM) module is connected with the first FPGA module and is used for caching data of the first FPGA module; and a second SRAM module is connected with the second FPGA module and is used for caching data of the second FPGA module. The digital radio frequency memory board has high-speed data acquisition and playback capacity, and the functions of data acquisition, storage, transmission and playback can be flexibly realized.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a digital radio frequency storage board. Background technique [0002] Based on high-speed sampling technology and digital storage technology, digital radio frequency storage technology has the ability to store and reproduce high-frequency signals, and is widely used in the radar field. [0003] At present, digital radio frequency storage technology is commonly used in radar signal test equipment to realize radar function and performance testing. The delay of the analog signal of the module needs to be as short as possible, and it is difficult to meet such a demanding requirement by using a general-purpose digital signal processor (DSP, Digital Signal Processer). Contents of the invention [0004] The invention provides a digital radio frequency storage board, which has high-speed data collection and playback capabilities, and can flexibly realize functions such as data c...
