The Keysight (Agilent) FieldFox N9913A is a 4 GHz handheld microwave combination analyzer designed for harsh field environments. Standardizing on a ruggedized, completely sealed portrait enclosure, it functions as a cable and antenna analyzer (CAT) as well as a vector network analyzer (VNA) and spectrum analyzer. Designed to provide benchtop-level accuracy with no warm-up required, the N9913A is optimized for field testing of satellite, military, and microwave backhaul communications.
