Having trouble capturing signals in busy airwaves? See how a handheld tool can record, stream, and replay wideband signals so you never miss anything.
RF teams working in the field face a new challenge. The spectrum is crowded, signals overlap, and interference events are short and unpredictable. With 5G, radar systems, satellite communications, and 6G testing happening at the same time, it is harder to capture wideband signals without gaps, stream IQ data in real time, or move large datasets fast enough for analysis. Many handheld analyzers cannot handle this. Bandwidth is limited, data streaming can stall, and transferring captured signals to the lab can be slow or incomplete.
Keysight Technologies’ FieldFox D-Series is for engineers who need lab-level performance in the field. Instead of capturing only pieces of a signal, users can stream and record wideband IQ data continuously. Interference, spectrum anomalies, and short events are less likely to be missed. Once captured, data can be replayed, analyzed, and recreated in the lab to verify system behavior and compare real-world conditions with simulation or design expectations.
To support this workflow, the analyzer offers 120-MHz gap-free IQ streaming and built-in SFP+ 10-GbE data transfer. Engineers can capture wideband signals in real time, troubleshoot issues, and monitor the spectrum. The device can also run over 25 software-defined applications—from VNA and real-time spectrum analysis to EMI testing and noise figure measurements—so one instrument can replace multiple tools.
Key specifications include:
- No warm-up time required for immediate use in the field.
- ±0.1 dB absolute amplitude accuracy.
- 14 configurations, supporting frequency ranges up to 54 GHz.
- Applications include defense, aerospace, telecom deployment, and spectrum monitoring.
- AI-based signal recognition for faster spectrum analysis.
- Works with Keysight’s Spectrum Management Software to automatically identify standards such as LTE, 5G NR, Wi-Fi, and Bluetooth.
- Helps engineers understand spectrum activity and locate issues without manual decoding.
The series is not just another handheld scanner. It helps teams detect problems faster, understand signals, and move from field capture to lab verification without losing data or wasting time.
