RFeye Node Plus – RF Sensor
RFeye Node Plus 100-18 overview
The RFeye Node Plus 100-18 is a high-performance spectrum analyzer and monitoring receiver designed for fast, long-distance data transfer via a 10 Gigabit Ethernet SFP+ port, supporting both fiber optic and copper connections. It covers a tuning range of 9 kHz to 18 GHz and features edge processing for full 100 MHz instantaneous bandwidth (IBW) recording, capture, and streaming. With a 120 dB dynamic range, 390 GHz/s sweep speed at 2 MHz RBW, and best-in-class frequency accuracy, tuning time, and phase noise performance, the sensor delivers exceptional RF sensing capabilities.
The RFeye Node Plus 100-18 delivers an optimal balance of SWaP-C and edge performance. Equipped with a high-speed processor, 10GigE SFP data interface, SSD port, and PCIe OCuLink port, it enables advanced RF intelligence capture and sharing, including full 100 MHz streaming via VITA-49. Geolocation streaming supports standard Asterix and Google Protocol Buffer data formats. Built for rugged environments, the sensor comes with a range of Control PC options.
