Description
Software Defined Radio Lab is a software programmable hardware transceiver which allows limitless communication laboratory experiments to be performed on a single device. The entry barrier is lowered to include the under graduate students by providing a graphical programming environment. The system is ideally suited for applications requiring high RF performance and great bandwidth such as physical layer prototyping, dynamic spectrum access and cognitive radio, spectrum monitoring and even networked sensor deployment.
The Superspeed USB 3.0 interface at 5Gbps serves as the connection between the SDR-LAB and the mobile workstation.This enables the user to realize 60 MS/s of real-time bandwidth in the receive and transmit directions, simultaneously (full duplex). FPGA is autoloading so hardware is plug and play as a pen drive! No need to program the FPGA for most cases!
The systems offer MIMO capability with high bandwidth and dynamic range. Two units may be connected to realize a
complete 2×2 MIMO configuration. External PPS and reference inputs can also be used to create larger multi-channel systems. ASIC houses complete RF and DAQ subsystems on a single board. Coupled with these benefits it hosts onboard RF Transceiver subsystems capable of tuning frequencies from 70MHz to 6GHz.
