The Keysight FieldFox B series combines cable & antenna tester (CAT), vector network analyzer (VNA) and spectrum analyzer (SA) in one robust, battery-operated handheld device. The analyzers are designed for tough field use - shockproof, dust and splash-proof to MIL standard, with a large transflective display, glove-operated keypad and replaceable battery for several hours of operation. CalReady ensures immediate measurement readiness after switching on; precise ECal calibrations are optionally available. The devices are fully software-defined and can be flexibly expanded to include options such as Real-Time Spectrum Analysis (RTSA), IQ Analyzer/Streaming, Noise Figure, Pulse and EMC measurements and Over-the-Air (OTA) for LTE and 5G. Typical applications include installation, maintenance and troubleshooting in cellular, satellite, radar, 5G, broadcast, defense and RF measurement environments.
The N9960B is part of the N996xB series within the FieldFox-B family and is a high-performance portable spectrum analyzer with an operating frequency range of 9 kHz to 32 GHz. It therefore addresses applications in the X to Ka band, e.g. in radar, satellite communications, 5G and RF system development. Compared to the N9953B (up to 54 GHz) or N9961B (up to 44 GHz), the N9960B offers an ideal compromise of bandwidth, sensitivity and mobility for users who require frequency ranges up to 32 GHz without sacrificing portability and energy efficiency. Like all models in the N996xB range, it supports extensive analysis functions - including RTSA, pulse analysis, noise figure, OTA and IQ data acquisition - and delivers laboratory precision in a compact, field-ready format. This makes the N9960B the ideal choice for engineers looking for a mobile radio frequency measurement system with maximum flexibility and precision.
