Keysight and 3dB Labs Signal Monitoring and Analysis Solution

The Keysight and 3dB Labs Signal Monitoring and Analysis Solution combines the portability and precision of Keysight’s FieldFox D-Series handheld analyzers with the advanced signal intelligence capabilities of 3dB Labs’ SCEPTRE® software and Monarch processing platform. Together, these technologies provide a comprehensive solution for RF signal monitoring, spectrum awareness, signal detection, geolocation, and analysis in demanding field and operational environments. Designed for engineers, spectrum operators, defense organizations, communications professionals, and electronic warfare teams, the integrated solution enables rapid discovery, characterization, and investigation of known, unknown, and anomalous signals across multiple domains. At the core of the solution is the Keysight FieldFox D-Series handheld analyzer family, engineered for rugged, portable RF field testing.

FieldFox instruments support system installation, verification, maintenance, troubleshooting, and spectrum monitoring tasks outside traditional laboratory environments. The platform combines multiple measurement functions within a single handheld instrument, including spectrum analysis, Vector Network Analysis (VNA), power measurements, signal generation, and real-time signal analysis. This consolidated approach reduces equipment burden while providing comprehensive measurement capabilities wherever missions require deployment. FieldFox D-Series analyzers are designed to support advanced field measurement workflows with broad frequency coverage extending up to 54 GHz across selected models. Features such as real-time spectrum analysis, high dynamic range measurements, gapless IQ streaming, and software-upgradable functionality enable users to adapt the instrument to changing operational requirements. The platform supports 40 MHz and 120 MHz streaming bandwidth options and includes high-speed interfaces such as SFP+, 10 Gigabit Ethernet, USB-C, and reference synchronization ports, allowing seamless integration with external processing and analysis systems. The ruggedized architecture and lab-grade measurement accuracy provide confidence in field-collected data while maintaining portability for mobile deployments. Complementing the measurement capabilities of FieldFox, 3dB Labs’ SCEPTRE software delivers advanced signal processing and analysis functions that transform collected RF data into actionable intelligence. SCEPTRE is built for both real-time and offline signal analysis and supports integration with a variety of software-defined radios and signal collection platforms.

The software enables users to identify, classify, locate, and investigate signals of interest across dynamic and congested spectrum environments. Through its scalable architecture, SCEPTRE supports remote spectrum operations, precision geolocation workflows, temporal analysis, and multi-discipline signal exploitation activities. A key strength of SCEPTRE software is its ability to support discovery of unknown or unexpected emissions. Spectrum Masking and New Energy Detection capabilities allow analysts to automatically create baseline spectral masks and identify deviations that may indicate new, unauthorized, anomalous, or emerging signal activity. By highlighting changes within complex electromagnetic environments, the software helps accelerate detection and analysis workflows while reducing the burden on operators. The platform also includes specialized communications analysis capabilities. Push-to-Talk functionality enables detection and decoding of a variety of digital and analog radio communications protocols, including FM, DMR, P25 Phase 1, P25 Phase 2, NXDN, and TETRA systems. These capabilities support communications monitoring, signal characterization, and investigative workflows commonly required in public safety, defense, spectrum enforcement, and mission-critical communications environments. For radar and electronic signal intelligence applications, SCEPTRE provides advanced Pulse Descriptor Word (PDW) parameterization and radar signal analysis tools. Features such as signal de-interleaving, clustering, and database correlation assist analysts in identifying radar emitters, characterizing signal activity, and organizing large volumes of collected spectrum data. These capabilities help users manage complex RF environments where multiple emitters and communication systems operate simultaneously. The integrated solution is further enhanced through the Monarch Laptop 10G platform, which is optimized specifically for SCEPTRE performance.

Monarch systems are custom-built and rigorously tested to support high-performance signal processing and analysis workloads. The platform enables full-band processing and archival of FieldFox D-Series 120 MHz IQ streams while providing direct high-speed connectivity through SCEPTRE-10G and 10 Gigabit Ethernet interfaces. This architecture allows users to capture, store, analyze, and exploit wideband spectrum data efficiently while maintaining mobility and operational flexibility. Together, Keysight FieldFox analyzers, SCEPTRE software, and Monarch processing platforms create a powerful ecosystem for RF signal monitoring, spectrum analysis, spectrum surveillance, electronic warfare support, communications intelligence, spectrum management, interference hunting, signal discovery, and field-based RF testing. The integrated solution delivers interoperable measurement and software intelligence capabilities that enable organizations to move beyond basic measurement and gain deeper insight into increasingly complex electromagnetic environments. Whether deployed for defense and security missions, communications monitoring, spectrum operations, electronic support activities, telemetry analysis, RF troubleshooting, or engineering validation, the Keysight and 3dB Labs Signal Monitoring and Analysis Solution provides users with a scalable and portable framework for collecting, processing, visualizing, and understanding RF spectrum activity. By combining trusted measurement hardware with advanced software analytics, the solution helps teams uncover the unknown, improve situational awareness, and accelerate decision-making across modern RF operational environments.
