Description

technical field

[0001] The invention relates to a dual-channel digital radio frequency storage board, which belongs to the technical field of data storage. 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 fields of radar and electronic warfare.

[0003] The sampling and playback rates of existing digital radio frequency memory boards are mostly below 500MSPS, which cannot meet the current requirements for acquisition, storage, processing, and playback of hundreds of MHz or even GHz broadband signals. Most of the digital radio frequency storage boards that can work at the GSPS rate have only one channel for data acquisition, processing, and playback, and cannot adapt to the application of multiple broadband signals.
