Meet the newest members of the FieldFox family here.

The Industry's Most Integrated Handheld Analyzer

Keysight's FieldFox portable analyzers are equipped to handle your toughest working environments during routine maintenance, in-depth troubleshooting, and anything in between. Choose the software-enabled Keysight FieldFox configuration that best meets your needs.

  • Get frequency coverage up to 54 GHz with precision comparable to benchtop results.
  • Configure FieldFox as a cable and antenna analyzer (CAT), vector network analyzer (VNA), spectrum analyzer, or an all-in-one combination analyzer.
  • Make 5G field test a reality with wide analysis bandwidth up to 120 MHz.
  • Capture small, interfering signals with wideband, real-time analysis
  • Perform measurements with one of the lightest instruments in the industry — 30% lighter than other handheld analyzers

Never Sacrifice Capability or Portability

Field testing modern communications networks puts new demands on your equipment and requires trade-offs between capabilities and portability. With over 22 software-enabled measurement capabilities in one portable, battery-powered unit, FieldFox is the most capable handheld analyzer in the industry. Stay ahead of changing measurement requirements by upgrading your handheld analyzer in the field with convenient, user-installable license keys.

  • CAT measures insertion loss, return loss, cable loss, distance-to-fault, and time-domain reflectometry
  • Full 2-port VNA measures all four S-parameters, magnitude and phase, time-domain analysis, and mixed-mode
  • Spectrum analyzer includes 5G NR and LTE over-the-air coverage/quality testing, channel power measurements, extended range transmission analysis, and RTSA
  • Additional functions include a power meter, vector voltmeter, I/Q analyzer, and more
