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 to filters/amplifiers and over-the-air analysis.
The N9917B is the microwave combination model of the B series and extends the operating frequency range up to 18 GHz. It thus covers the full C, X and Ku bands and is ideal for applications in satcom, radar and defense systems as well as for broadband HF communication tests. Compared to the N9916B (up to 14 GHz), the N9917B offers additional band reserve for frequencies above 14 GHz, while retaining all the features and options of the series - including CalReady and InstAlign for instant calibration and maximum measurement accuracy. Users who work in higher frequency ranges or want additional future-proofing can choose the N9917B as a more powerful alternative within the series.
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.
- Frequency ranges depending on model: from 30 kHz to 26.5 GHz (N9912B to N9918B); the N9917B covers up to 18 GHz.
- Ruggedized design: for field use (-10 ... +55 °C), shock/vibration resistant; dust and splash-proof construction.
- Mobile & ergonomic: approx. 3.3 kg, large transflective display, large buttons, glove-operated, replaceable battery (several hours running time).
- High measurement accuracy: InstAlign for very good amplitude accuracy in the SA, CalReady immediately after switching on; support for USB ECal modules.
- Flexible analysis: Options for RTSA (up to 120 MHz real-time BW), IQ acquisition/streaming, noise figure, pulse and EMC measurements, OTA (LTE/5G), channel scanner, interference/spectral monitoring.
- VNA performance: wide IF-BW range, fine dots (up to 10 001), flat output power, comprehensive calibration procedures (including Unknown Thru, QSOLT, TRL).
- Interfaces & GPS: USB & LAN, external Ref/Trigger, optional integrated GNSS, support for external USB power sensors and built-in power meter (option).
