Keysight FieldFoxHandheld RF and Microwave Analyzers

SHARE

Makes 5G test a reality with a wide analysis bandwidth — up to 100 MHz — over-the-air (OTA) measurement options, and much more. Captures the smallest interfering signals with wide-band, real-time analysis (RTSA). Measures from 4 to 50 GHz with precision comparable to benchtop results. Withstands your toughest working environments — meets MIL-specs.  Weighs less than alternative solutions — 30% lighter than other handheld analyzers. Performs as a cable and antenna analyzer (CAT), a VNA, a spectrum analyzer, or as an all-in-one combination analyzer.
