Problems solved by technology

[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 multi-channel broadband signals.

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] A dual-channel digital radio frequency storage board includes two relatively independent data acquisition, processing and playback branches, which are left processing branch and right processing branch. Such as figure 2 As shown, the left processing branch includes: an ADC-L chip as an ADC data acquisition module, model AT84AD001BITD; a V4-L chip as an FPGA acquisition control module, model XC4VSX55; a piece of DAC-L chip as a DAC data playback module L chip, the model is AD9736BBC. The right processing branch includes: an ADC-R chip as an ADC data acquisition module, model AT84AD001BITD; a V4-R chip as an FPGA acquisition control module, model XC4VSX55; a DAC-R chip as a DAC data playback module, The model number is AD9736BBC. These two relatively independent data acquisition, processing and playback branches share a V5 chip as the F...

The two-channel digital radio-frequency memory board is provided with two signal acquisition processing playback circuit branches, and each circuit branch has the sampling rate of 1.2GSPS and the playback rate of 1.2GSPS; and the two-channel digital radio-frequency memory board has various signal acquisition processing playback modes and data transmission mode, can realize functions of memorizing and forwarding signals with high frequency, and is suitable to be applied to the field of radar and electronic warfare confrontation.

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. Contents of the invention [0004] The purpose of the present invention is t...
