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 field use: shockproof, dustproof and splashproof, with a large display that is easy to read in sunlight, large buttons (can also be operated with gloves) and a field-swappable battery for several hours of measurement operation. Thanks to CalReady, the device is ready to measure as soon as it is switched on; optional ECal modules speed up precise calibrations. Software options such as Real-Time Spectrum Analysis (RTSA) up to 120 MHz, IQ Analyzer/Streaming, Noise Figure, Pulse Measurements, EMF/EMI and OTA Measurements (LTE/5G NR) are available for demanding applications. Typical areas of application include installation, troubleshooting and maintenance of mobile radio, SAT, radar, broadcast, WLAN and industrial RF systems - from cable termination to filters/amplifiers and over-the-air analysis.
The N9916B is the 14 GHz combination model of the B series and therefore covers a wide RF and microwave range (from 30 kHz). It is ideal for commissioning and servicing mobile radio and radio relay systems, aerospace and defense applications as well as industrial RF measurement tasks. Compared to the next higher N9917B (up to 18 GHz), the N9916B offers a price/performance sweet spot for all applications up to 14 GHz (e.g. sub-6 GHz 5G, many ISM/industrial bands, L/S/C-band radar tests, lower Ku-band). However, if you need full Ku-band pass-through, certain satcom downlinks or higher reserve up to 18 GHz, choose the N9917B. The range of functions, operation, robustness and options are the same throughout the series; the main difference lies in the maximum frequency range.
Technical product features of the series:
- Meter combination: CAT (DTF/TDR, RL/VSWR, cable & insertion loss), full 2-port VNA (S-parameter), spectrum analyzer with optional RTSA.
