Product Overview

FieldFox is equipped to handle routine maintenance, in-depth troubleshooting and anything in between. FieldFox delivers Keysight-quality measurements – wherever you need to go. Add FieldFox to your kit, and carry precision with you. The microwave combination analyzer's base function is a cable and antenna analyzer and it can be configured to include a spectrum and network analyzer.

FieldFox can be ordered with additional capabilities: power meter, independent signal generator, vector voltmeter, interference analyzer, variable DC source, built-in GPS receiver, and remote control using an iPad or iPhone. The future is Ka band. Now, there’s a rugged, dependable handheld designed to deliver precise, lab-grade measurements up to 50 GHz. At only 7.1 lbs., it’s an all-in-one cable and antenna tester (CAT) + vector network analyzer (VNA) + spectrum analyzer and more.

Which means, now you get comprehensive system performance insight at higher frequencies. Plus with easy upgrades and multiple configurations, you’ll be ready to go where no handheld has gone before — today and beyond.
