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 N9962B is part of the N996xB series within the FieldFox-B family and is one of the most powerful portable spectrum analyzers in its class. With an operating frequency range of 9 kHz to 50 GHz, it is ideal for demanding applications in the Ka and V-band, such as 5G mmWave, radar, satcom, defense and RF test systems. Compared to the N9961B (up to 44 GHz), the N9962B extends the frequency range up to 50 GHz and thus enables precise characterization of signals, antennas and components in the upper millimetre wave range. It combines maximum measurement accuracy, wide bandwidth and mobility in a single device while remaining fully compatible with the familiar FieldFox architecture. Like all models in the series, it supports RTSA, pulse, noise figure, OTA, EMC and IQ analyses, offering maximum flexibility for demanding RF and microwave measurements in the field and laboratory.
