The Keysight N9910X is a comprehensive accessory series designed to extend the measurement capabilities of FieldFox handheld RF and microwave analyzers. This modular collection includes directional and omnidirectional antennas, phase-stable cables, and coaxial adapters—each engineered to support field testing and maintenance across diverse RF and microwave system architectures.
Technical Specifications
Antennas
The series offers multiple antenna configurations spanning 70 MHz to 18 GHz. The N9910X/822 handheld directional log-periodic antenna covers 600 MHz to 9 GHz with 5 dB typical gain, VSWR < 3:1, and a pivoting handle enabling both vertical and horizontal polarization. It accepts Type-N female connectors and withstands 10 Watts maximum power. The N9910X/820 multiband directional antenna operates from 800 MHz to 2500 MHz with 10 dBi gain. Additional options include telescopic whip (70 MHz to 1 GHz), retractable whip (70 MHz to 1000 MHz), omnidirectional portable (70 MHz to 2500 MHz), and log-periodic directional models at 700 MHz to 4 GHz, 680 MHz to 8 GHz, and 680 MHz to 18 GHz. A GPS active antenna is available for compatible FieldFox models.
Cables
Phase-stable cable assemblies include the N9910X/701—1 meter Type-N (m) to Type-N (m) rated to 18 GHz with 1.13 dB typical insertion loss, ±2.0° phase stability, and 1.19 typical VSWR. Additional configurations support TNC and 3.5 mm connectors, with frequency ratings from 6 GHz to 26.5 GHz. Specialized cables include the N9910X/714 (2.4 mm female to male, 50 GHz, 1 m), plus trigger/reference-in and bias-tee power assemblies.
