The Keysight N6841A RF Sensor provides an extremely cost effective way to improve spectral awareness. The RF Sensor is enclosed in a weatherproof case allowing wide area, close-proximity signal monitoring, detection and location in any environment. Its open programming interface allows users to dynamically link to a wide range of software applications. An Ethernet TCP/IP network connection allows for remote deployment of a network of multiple sensors within a single room, throughout a city, or across the world.


  • Wideband RF receiver with 20 MHz to 6 GHz tuning range and 20MHz Digital IF bandwidth
  • 2 Switched RF Inputs with broad attenuation and wide dynamic range
  • Signal capture using deep memory buffer (512 MB) or IQ streaming (up to 1.9MHz bandwidth)
  • Timing synchronization accuracy less than 20ns for GPS and less than 40 ns for IEEE-1588


  • Frequency Regulators needing ITU-R spectrum monitoring systems or interference detection and location systems
  • Government and Industry Frequency Managers needing spectrum monitoring for test range management
  • Spectrum Security and Policy Managers needing in-place monitoring systems and indoor emitter locations systems
  • Engineers needing affordable high-speed, high-resolution search, intercept and tipping systems

Outdoor deployable:

  • IP67-rated weatherproof enclosure
  • Mobile or fixed site deployment using battery power or optional mains adaptor


  • Spectrum Monitoring, Signal intercept, collection and classification using the N6820ES Signal Surveyor software

  • Signal Capture and Analysis using the Vector Signal Analyzer software
  • Emitter location and RF Geo-Analytics using the N6854A Geolocation Server software
  • Remote spectrum and signal monitoring and collection using Keysight Spectrum Visualizer software
  • Custom applications, written using the Sensor Access Library (SAL) API.
  • A growing list of third party applications
