Handheld analyzer from Keysight targets 120 MHz IQ streaming in the field
Keysight Technologies has introduced the N99xxD FieldFox handheld analyzer for engineers working in increasingly congested RF environments. The handheld analyzer supports 120 MHz gap-free IQ streaming and high-speed 10 GbE data transfer for wideband signal capture directly on site. It is positioned for spectrum monitoring, interference hunting and field verification tasks that would traditionally rely on benchtop instruments.
For eeNews Europe readers, the product could help RF design and test teams in Europe characterise 5G, radar, satellite and emerging 6G signals closer to deployment. It may also be relevant for spectrum regulators and defence users who need portable tools that still integrate into lab-grade workflows.
FieldFox D-Series focuses on wideband RF troubleshooting
The N99xxD-Series extends Keysight’s FieldFox family with a focus on wideband signal analysis in demanding RF environments, from commercial networks to mission-critical systems. According to the company, the platform combines the rugged mechanics expected of a field unit with measurement performance that potentially approaches lab analysers, aiming to reduce the risk of missed transient or intermittent events.
Key specifications include 120 MHz gap-free IQ streaming with integrated SFP+ interfaces for 10 GbE links, which potentially enables uninterrupted data capture and efficient offload to storage or analysis back-ends. Wideband analysis and playback are intended to support tasks such as spectrum utilisation monitoring, interference hunting and characterisation of complex modulation schemes.
The N99xxD-Series spans 14 handheld analyzer models, in combination and spectrum-only variants, with maximum frequencies of 14, 18, 26.5, 32, 44, 50 and 54 GHz. More than 25 software-defined applications are available, including vector network analysis, real-time spectrum analysis, noise figure, EMI diagnostics, pulse analysis and direction-finding based on angle of arrival and time difference of arrival. A Linux-based operating system is used to tighten security and file management, while a touchscreen interface is intended to improve usability and reduce setup errors.
Gap-free IQ streaming links field and lab workflows
Keysight positions the FieldFox D-Series as a bridge between field measurements and lab analysis. Gap-free IQ streaming at 120 MHz is combined with tools to recreate real-world scenarios on benchtop instruments, which could help European labs validate designs against in-situ conditions seen on 5G, satellite or defence sites. The company cites absolute amplitude accuracy of ±0.1 dB without warm-up, a figure that potentially differentiates the platform from typical handhelds and some benchtop instruments.
The handheld analyzer is also tied into Keysight Spectrum Management Software (KSMS S9910A) and a machine-learning model (S9916A) that classifies major wireless standards such as LTE, 5G NR, Wi-Fi and Bluetooth. This AI-assisted workflow is intended to shorten time-to-resolution in congested or contested spectrum, an area of particular interest for regulators and defence users in Europe.
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 to 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’.”
