Looking to improve the complex radio frequency (RF) environment as commercial and consumer systems converge, Keysight Technologies Inc. has introduced a handheld analyzer enabling 120-MHz gap-free IQ streaming for high-speed data transfer and field-to-lab integration.
Called N99xxD-Series FieldFox, the handheld analyzer is a ruggedized field instrument that has the power and precision of a lab analyzer, Keysight said. It allows users to capture, stream and replay every signal event. This provides faster troubleshooting, deeper analysis and certainty of the data collection process, the company said.
The N99xxD-Series FieldFox features include:
- 120 MHz IQ streaming with built-in SFP+ high-speed data interfaces for 10 GbE data transfer
- Wideband signal analysis and playback for advanced troubleshooting
- Field-to-lab workflow
- Absolute amplitude accuracy of ±0.1 dB — without warm-up
The series includes 14 models that covers 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
- Direction-finding using techniques like angle of arrival (AoA) and time difference of arrival (TDoA)
Why it matters
Keysight said that RF environments are increasingly complex and dynamic especially as consumer and commercial systems are converging in the spectrum. 5G, radar, 6G and SATCOM are challenging engineers in identifying interference, capturing transient events, and characterizing wideband signals without data loss.
Other handheld analyzers often fall short — limited by bandwidth, streaming speed or data-transfer bottlenecks, Keysight said.
The FieldFox analyzers leverage wideband signal capture and machine learning models to automatically reduce time-to-resolution and offers deep insights into contested or congested spectrum environments.
