High-precision, high-speed architecture delivers the visibility engineers need to navigate increasingly crowded and complex RF landscapes

SANTA ROSA, Calif.: Keysight Technologies, Inc. (NYSE: KEYS) introduced the N99xxD-Series FieldFox Handheld Analyzer, the latest evolution of Keysight’s trusted FieldFox family. Purpose-built for precision and portability, the new D-Series enables 120 MHz gap-free IQ streaming, high-speed data transfer, and seamless field-to-lab integration, setting a new benchmark for wideband signal analysis in demanding RF environments.

Today’s radio frequency (RF) environments are becoming increasingly complex and dynamic, as mission-critical, commercial, and consumer systems converge across the spectrum. From 5G and radar to emerging 6G and satellite communications, engineers face mounting challenges in identifying interference, capturing transient events, and characterizing wideband signals without data loss. Traditional handheld analyzers often fall short - limited by bandwidth, streaming speed, or data-transfer bottlenecks

The new FieldFox D-Series bridges this gap by combining the ruggedness of a field instrument with the power and precision of a lab analyzer. It empowers users to capture, stream, and replay every signal event, enabling faster troubleshooting, deeper analysis, and greater confidence that no data is missed, even in the most complex RF landscapes.

Key capabilities of the N99xxD-Series FieldFox handheld analyzer include:

• 120-MHz IQ streaming with built-in SFP+ high-speed data interfaces for 10 GbE data transfer, ensuring uninterrupted data capture and efficient streaming
• Wideband signal analysis and playback for advanced troubleshooting in complex RF environments, spectrum utilization monitoring, and interference detection
• Seamless field-to-lab workflow, enabling re-creation of real-world signal scenarios for in-depth lab analysis and system optimization
• Unmatched RF performance, delivering absolute amplitude accuracy of ±0.1 dB -without warm-up - surpassing most handheld and benchtop analyzers currently in the market

The N99xxD-Series includes 14 models (combo or spectrum analyzers) to cover the maximum frequency of 14, 18, 26.5, 32, 44, 50, and 54 GHz. Each model supports more than 25 software-defined FieldFox applications, including vector network analysis, spectrum and real-time spectrum analysis, noise figure measurement, electromagnetic interference analysis, pulse signal generation, and direction-finding using techniques like angle of arrival (AoA) and time difference of arrival (TDoA). A Linux-based operating system further enhances the analyzer’s security and file management, while a touchscreen interface improves usability, efficiency, and reduces errors.

Keysight has introduced advanced artificial intelligence (AI) capabilities to its FieldFox handheld analyzers and Keysight Spectrum Management Software (KSMS S9910A), delivering faster and smarter spectrum operations. By leveraging wideband signal capture and the new machine learning model (S9916A), the solution now classifies major wireless standards - including LTE, 5G NR, Wi-Fi, and Bluetooth - with exceptional speed and accuracy. This integration automatically and dramatically reduces time-to-resolution and provides deep insights into congested or contested spectrum environments, empowering customers to make informed decisions in real time.

Eric Taylor, General Manager and Vice President of Keysight Aerospace, Defense, and Government Solutions, said: “Keysight is committed to delivering robust, efficient tools that empower customers tackle demanding field tasks. With high-speed interfaces, gap-free streaming, and secure Linux operations, the new FieldFox D-Series redefines portable RF analysis - bringing capabilities like signal sensing, geolocation, and spectrum management into a rugged handheld platform. Its software-defined architecture lets users add new capabilities onsite, giving them flexibility to move faster and be ‘first-to-market’.”
