The GRXLAN family of SDR’s (software definable receivers) provides a cost effective solution where single or multiple receiver channels are required in a communication EW environment. The receivers provide base band I/Q outputs, which then may be manipulated to derive spectral information including demodulation for listening purposes.
With multiple receiver channels in a rugged and compact rack, the GRX receivers are suitable for fixed and mobile applications.
Meeting the challenge of the modern HF & V/UHF signals scenario, the GRX-LAN receiver series utilizes the latest technology to achieve outstanding receiver performance.
High dynamic range circuitry, with Digital Signal Processing and sophisticated host man-machine interface graphics combine in a cutting edge SDR solution for modern HF & V/UHF ESM monitoring requirements.
LAN interface offers stand alone and advance system applications.
