Radio Frequency Recording and Playback System

System principle:

The RF recording and playback system consists of a host computer, USRP-LW X310, UBX-LW 160 and an antenna. During signal acquisition, the system receives wireless electromagnetic signals through USRP-LW X310, UBX-LW 160 and antennas, and the signal data is saved to the hard disk through the host computer. During signal playback, the collected signal data is selected by the host computer, and the data is transmitted to the electromagnetic environment through USRP-LW, UBX-LW 160 and the antenna.

System function:

The main function of the RF recording and playback system is to quickly capture, display and save the signals in the wireless electromagnetic signal environment. The system provides data analytics tools, which can be used for secondary processing and analysis in Matlab. The collected data can be quickly transmitted to the wireless electromagnetic environment after relevant processing, which is convenient for users to quickly reconstruct the complex wireless electromagnetic environment.

System application:

The RF recording and playback system can help users quickly build a large-bandwidth electromagnetic signal acquisition and system. Modeling and analysis of various electromagnetic environment channels can be used to quickly build interference systems.
