FieldFox is a new high-performance handheld microwave analyzer that speeds installation of 5G, radar, and satellite communication systems. It has a task-driven user interface and provides spectrum and signal analysis, as well as signal generation capabilities. This enables FieldFox to accurately measure signal interference, antenna and cable performance, electromagnetic field (EMF) exposure levels, as well as pathloss in communication systems. This high performance installation tool ensures 5G services in frequency range 2 (FR2) can reach full connectivity potential. Benefits include simplification of setup and improved measurement results in any 3GPP-specified band in FR2 by extending the frequency range to 54 GHz without the need for external mixers, support of advanced channel aggregation and complex interference troubleshooting with an increased analysis bandwidth range up to 120 MHz, and reliable analysis of complex signals with industry-leading low phase noise, high sensitivity, and amplitude accuracy.
