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 are installation, troubleshooting and maintenance of mobile radio, SAT, radar, broadcast, WLAN and industrial RF systems - from cable termination and filters/amplifiers to over-the-air analysis.
The N9952B is part of the N995xB series within the FieldFox-B family and is an advanced portable spectrum analyzer with an operating frequency range of 9 kHz to 50 GHz. It is designed for applications requiring the highest precision in millimeter wave, radar, 5G, defense and satellite communication systems. Compared to the N9951B (up to 44 GHz), the N9952B extends the frequency range into the V-band and enables the analysis of high-frequency signals in state-of-the-art communication and sensor systems. Despite its enormous performance, it remains compact, field-ready and fully compatible with the proven FieldFox platform. The N9952B supports all common analysis options - from RTSA and IQ streaming to pulse, EMC and OTA measurements - and combines maximum bandwidth with maximum robustness for mobile applications in the radio frequency range.
