Recording and playback of sub6g 5g NR signal based on USRP x310

     Based on the generation and acquisition capabilities of x310 and Ubx wideband signals, an outfield signal acquisition and playback system is built for a wireless communication technology company. The maximum signal acquisition and generation bandwidth of Ubx is 160MHz, which can fully meet the carrier bandwidth requirement of 100MHz for 5g NR signal. Meanwhile, it has a large dynamic range, which also guarantees the acquisition and playback quality of 5g NR signal. By recording the field signal, the electromagnetic environment or interested signal can be reproduced and used for the test of the tested object in the laboratory. The test system can not only be used for recording and playback of 5g NR, but also suitable for any other scene recording or constructing low-cost test solutions such as GPS signal
