Designed for superior durability and reliability, the VPX3-E320 incorporates Curtiss-Wright’s industry-leading rugged hardware design and validation practices to meet the stringent requirements of the most demanding front-line environments. Paired with the industry-leading UHD-based software-defined radio workflow, this product is truly unique. Bringing the NI Ettus Research USRP E320 to the VPX form factor, the VPX3-E320 is a ruggedized, user-programmable software-defined radio, ideal for low-to-medium bandwidth RF applications and aligned to The Open Group Sensor Open Systems Architecture™ (SOSA) and U.S. Army’s C5ISR/EW Modular Open Suite of Standards (CMOSS) Technical Standards. This product is compatible with the USRP Hardware Driver (UHD) maintained by NI in a VPX SDR.

Just like the NI Ettus Research USRP E320, the VPX3-E320 features a flexible 2 x 2 MIMO RF Agile Transceiver with 12-bit ADC and DACs. The board supports tunable bandwidths from 200 kHz to 56 MHz over a frequency range from 70 MHz to 6 GHz.

Baseband signal processing uses an AMD Zynq 7045 System-on-Chip FPGA to deliver accelerated FPGA computations and software-based processing using its dual-core Arm® CPU. Device configuration can be accomplished with the NI USRP Hardware Driver (UHD), either through GNU Radio or with common programming languages such as Python or C++. Applications previously developed on the USRP E320 will port directly to the VPX3-E320.
