Keysight FieldFox Handheld RF Analyzers

Carry precision with you

  • NEW Wider analysis bandwidth – up to 100 MHz – makes 5G field test a reality
  • NEW Capture the smallest interfering signals with wide-band, real-time measurements (RTSA)
  • Measure with confidence from 4 to 54 GHz – precise measurements agree with benchtop results
  • Withstands your toughest working environments – rugged enough to meet MIL-specs
  • Weighs less than alternative solutions- millimeter-wave models 30% lighter than other handhelds
  • Choose to configure as a cable and antenna analyzer (CAT), vector network analyzer (VNA), spectrum analyzer or an all-in-one combination analyzer

Interference Hunting with the Keysight FieldFox

Identify and locate the source of unwanted signals with real-time spectrum analysis.

Interference hunting involves identifying and locating the source of unwanted radio signals or interference in a communication system. These disruptions can stem from co-channel, adjacent channel, or broadband interference. Direction finding (DF) techniques enable operators to pinpoint the exact location of the interfering source.
