SDR-LW 3940 Note is the latest four-channel high-performance SDR (Software Defined Radio) standalone device launched by LUOWAVE, consisting of an onboard processor, FPGA, and RF front-end. The FPGA utilizes the resource-rich and user-programmable Xilinx MPSoC ZU11EG. This SDR device features a built-in Ubuntu system and integrates application software such as GNU Radio.
The SDR-LW 3940 Note has 4 transmit channels and 4 receive channels, supporting an instantaneous bandwidth of 200MHz per channel. High-speed interconnection between the host and the SDR board is achieved via PCIe Gen3 x8, constructing a full-link data processing path with high throughput and low latency. With precise clock management and synchronization signal processing mechanisms, the Luowave LW320 provides excellent phase consistency and collaborative capabilities. The 3940 Note is the ruggedized all-in-one version of the Luowave LW420, significantly enhancing environmental adaptability and operational stability through its reinforced structure and professional display, making it particularly suitable for field testing and application requirements in complex environments.
