Keysight N9916B 14 GHz FieldFox Handheld Microwave Analyzer

The Keysight N9916B 14 GHz FieldFox Handheld Microwave Analyzer is a portable instrument for installing, maintaining, and troubleshooting RF and microwave systems. It combines standard cable and antenna testing with optional spectrum and vector network analysis, providing several measurement functions in one device.

Its cable and antenna analyzer helps technicians assess cables, connectors, and antennas. Return loss and voltage standing wave ratio (VSWR) measurements reveal signal reflections that can indicate poor matching. Distance-to-fault measurements help locate problems along a cable, supporting repairs and installation checks.

With the spectrum analyzer option installed, the N9916B measures signal strength across frequencies from 9 kHz to 14 GHz. This allows users to investigate interference and unwanted emissions. Optional real-time spectrum analysis captures intermittent signals with up to 120 MHz of analysis bandwidth.

Optional vector network analysis measures how components transmit and reflect signals from 30 kHz to 14 GHz. Full two-port S-parameter measurements characterize magnitude and phase, helping engineers evaluate filters, amplifiers, and cables for transmission loss, reflections, and reverse isolation.

Designed for field work, the N9916B weighs approximately 3.4 kilograms (7.4 pounds) and includes a rechargeable battery and carrying case. Available options add power measurement, interference monitoring, GPS positioning, and LTE or 5G NR over-the-air testing. Each unit’s capabilities depend on its installed options and accessories.
