The various types and varieties of wireless technologies pose an escalating challenge for intelligence and homeland-security agencies. Whether the mission is to intercept, collect, detect, monitor and track, or trend and analyze, our diverse technology base and deep familiarity with wireless communications gives you an edge that increases the probability of sooner detection, assessment, and response.

Keysight solutions for spectrum monitoring and signal analysis include a range of portable and benchtop tools plus software for monitoring the many wireless signals that are crowding the spectrum.

Spectrum Monitoring Receivers

Wireless technologies pose an ever-increasing need to monitor the RF spectrum and protect against RF interferers. Keysight provides the range of spectrum monitoring tools you need from high performance signal analyzers to remote weather proof sensors to affordable hand-held signal analyzers.

Emitter Location Workflow

Below are the primary steps you need to perform emitter location.
  1. Deployment Planning and Modeling
  2. RF Survey, Signal Classification
  3. Emitter Location
  4. Signal Analysis and Identification
  5. Spectrum Data and Report Generation

Automating RF Survey, Signal Classification

The N6820ES Signal Surveyor 4D software is compatible with many RF receivers, including the N6841A RF Sensor, M9393A PXI Vector Signal Analyzer, FieldFox Handheld Analyzer, and more. The software enables awareness of spectrum use with gap-free monitoring, advanced energy detection, triggers, and automatic alarm tasking.

Emitter Location

Powerful geolocation algorithms using time difference of arrival (TDOA), received signal strength (RSS) or a unique adaptive hybrid technique provides pin point location of unknown RF emitters using a network of N6841A RF sensors. You can export geolocation results and SQL database or mapping software such as Google Earth.

Signal Analysis and Identification

Once an IQ time-series recording is made, you can load the recording into Keysight 89601B Vector Signal Analysis software to be analyzed, demodulated and classified.
