Description
Feed lines, antennas and microwave links all need checking, and that usually means several instruments. The Keysight N9952B FieldFox analyzer folds much of that into one portable unit that reaches 50 GHz. It runs on battery, weighs approximately 3.4 kg and keeps cable and antenna test in the base configuration. Lost in HCM lists it for rental and sale, with service on request.
One handheld, several measurement jobs
This FieldFox combines cable and antenna test with optional vector network and spectrum functions. Full two-port S-parameters are optional, and so is real-time spectrum analysis with up to 120 MHz of bandwidth. Time-domain measurements also support troubleshooting in the field.

Checking cables, antennas and feed lines
Reflection and transmission tests show whether a cable, connector or antenna still performs. Set up the instrument with the right calibration standards and connector interfaces first. Then keep the same setup while you compare assemblies. For example, you can compare a new feed line with an old one on the same day.
On-site work beyond the antenna
- Maintenance on 5G, microwave and satellite links with the Keysight N9952B FieldFox analyzer.
- Portable spectrum monitoring and interference hunting.
- VNA measurements on site, all the way to 50 GHz.
However, the advanced functions are software options. A unit may lack the VNA or real-time functions, so confirm them for the offered serial number.
