The USRP family of products is designed for RF applications from DC to 6 GHz, including multiple-antenna (MIMO) systems. Example application areas include white spaces, mobile phones, public safety, spectrum monitoring, radio networking, cognitive radio, satellite navigation, and amateur radio.

NI, through the Ettus Research brand, offers a premium software-defined radio portfolio combining ease of use and a robust open-source software community.  Leveraging the power of the USRP Hardware Driver&#; (UHD), engineers have access to an ecosystem of software options, from open-source to graphical system design.

The open-source GNU Radio software code repository helps engineers interface with hundreds of active members supporting other users and growing the codebase.

Through this open-source community, GNU Radio software continues to evolve and address more applications including RF and communications system design encompassing both MAC and PHY research, spectrum monitoring and signal intelligence, and wireless sensors and tracking.

Among other software options, engineers can program with a graphical system design approach using NI LabVIEW software. With NI and Ettus software-defined radio hardware and LabVIEW, they can prototype their wireless systems faster and significantly shorten their time to results. NI and Ettus offer a complete platform with an option to reuse existing software tools for simplified programming in a unified design flow that scales from design to deployment.

Universal Software Radio Peripheral

The Universal Software Radio Peripheral (USRP) is a versatile and flexible hardware platform that enables software-defined radio (SDR) capabilities. It has become popular in the SDR community due to its openness and modifiability.

The USRP consists of two main components:

1. RF Frontend: The RF frontend includes a wideband radio frequency (RF) transceiver with configurable parameters like frequency range, bandwidth, and modulation schemes. It allows the USRP to receive and transmit radio signals across a broad range of frequencies, typically from tens of megahertz to several gigahertz.

2. FPGA and Processor: The USRP incorporates an onboard Field-Programmable Gate Array (FPGA) and a processor (usually an embedded processor like an ARM CPU). The FPGA provides hardware-level programmability, allowing for real-time signal processing and digital radio functionalities. The embedded processor handles tasks like communication with the host computer, data streaming, and managing higher-level functions.

The key advantage of the USRP is its ability to be controlled and configured by software running on a host computer. Users can program the USRP's FPGA to implement custom signal processing algorithms, modulations, and protocols. This software-defined approach eliminates the need for dedicated hardware for each communication standard, making it possible to reconfigure the radio for various wireless applications without physical modifications.

USRP devices are widely used in a range of applications, including:

1. Research and Development: USRPs are popular among researchers and developers working on wireless communication systems, protocol analysis, and signal processing. They offer a flexible platform for experimenting with new algorithms and protocols.

2. Communication Prototyping: In the field of wireless communications, USRPs are used to prototype and test new communication standards, enabling rapid iteration and development.

3. Education: USRPs are valuable tools for teaching and learning about SDR principles, wireless communication, and digital signal processing.

4. Cognitive Radio: USRPs can be used in cognitive radio systems, which aim to intelligently adapt to the radio frequency spectrum's available resources.

5. Radio Monitoring and Security: SDR capabilities of USRPs enable monitoring and analyzing radio signals, making them useful for radio spectrum monitoring, security, and surveillance applications.

Universal Software Radio Peripheral offers a powerful and flexible solution for working with software-defined radio, empowering researchers, developers, and enthusiasts to explore and innovate in the field of wireless communications.
