The RFeye Node 40-8 from CRFS is a Purpose-Built RF Receiver for spectrum regulators from 9 kHz to 8 GHz with an instantaneous bandwidth of 40 MHz. It combines high performance spectrum monitoring with a rugged form factor at an affordable price. This receiver provides real-time spectrum operations and is low in Size, Weight, and Power (SWaP) making it easy to deploy where it is needed. It has a sampling rate of 62.5 MS/s I&Q and uses the latest superheterodyne receiver technology to provide outstanding quality and performance at a competitive price. The receiver is a complete spectrum monitoring and geolocation system designed for evaluating remote deployment in distributed networks both indoors and outdoors, including in hostile environments.

The RFeye Node 40-8 is characterized by outstanding noise figure, channel re-tune time and spurious free dynamic range parameters. It also allows multiple concurrent measurements and geolocations to be performed and multiple users to connect simultaneously from remote locations. It has a noise figure of 10 dB (9 kHz to 100 MHz) and a phase noise of -103 dBc/Hz at 20 kHz offset (receiver input at 1 GHz). With exceptional sensitivity, low power and low data back-haul requirements, this receiver delivers uninterrupted spectrum vigilance.

The RFeye Node 40-8 is powered by an Intel E3845 quad-core CPU and uses the Linux, kernel v2.6 operating system. It has an Ethernet port for networking, USB2.0/3.0 ports, 2 x IEEE1394 expansion ports and one SMA passive or active port for GNSS antenna input. The RFeye Node 40-8 requires a DC supply of 12 V with support for Power over Ethernet and consumes less than 25 W of power. It is available in compact, rugged, weatherproof housing that measures 200 x 50 x 130 mm with 4x SMA connectors. The receiver is ideal for regulators (spectrum management and interference hunting), defense (test range spectrum management) and security (technical surveillance counter measures) applications.
