The N99xxD-Sequence helps wideband sign evaluation to tackle among the most difficult RF environments
In sum — what to know:
Keysight touts new RF analyzer: Keysight rolled out the brand new N99xxD-Sequence FieldFox handheld analyzers with wideband sign evaluation capabilities of RF environments.
Powered with AI/ML: The brand new analyzers faucet AI/ML algorithms to ship lab-grade precision within the area and diminished time-to-resolution.
A full suite: The collection consists of 14 fashions providing protection of as much as 54 GHz.
We’re within the homestretch of 2025, however the market ain’t slowing down for that. Keysight simply introduced a brand new set of handheld RF analyzers. The N99xxD-Sequence, with 120-MHz IQ streaming and field-to-lab workflow, guarantees “gap-free” seize and lab-grade precision out within the area.
The D-Sequence builds on Keysight’s FieldFox household of transportable analyzers that the corporate positions for routine upkeep of probably the most demanding work environments.
Operating on a Linux-based OS, the brand new iteration permits engineers to report, stream, and replay real-world occasion utilizing high-speed 10 GbE knowledge transfers, chopping down evaluation time and time-to-resolution.
“FieldFox D-Sequence works as an entire spectrum administration system…seize, analyze, and act on wideband indicators in a single unified, field-ready workflow,” stated Kelly Loula, product skilled, Keysight.
In the present day’s RF environments span interational borders, stretching from civil societies to distant navy bases. With new mobile, satellite tv for pc and radio hyperlinks deployed regularly, explosion of IoT and related units, and bodily propagation complexities, the RF panorama presents many challenges together with however not restricted to packed airwaves, intermittent emitters — and worst of all, obstructed visibility.
Points like transient radar bursts, intermittent interference from satellite tv for pc uplinks or 5G programs, spoofed or unauthorized transmissions, and low-power emitters, can have an effect on the well being of transmissions, resulting in penalties starting from small streaming disruptions to lack of lives.
With conventional handheld analyzers offering slender bandwidth views, engineers threat lacking quick, weak, and misleading radio indicators which can be exhausting to catch.
“With out wideband seize, unified workflows, and geolocation instruments, these indicators are exhausting to detect, classify, and find in time,” Loula stated.
The D-Sequence bypasses these with end-to-end gap-free seize in a continous workflow. One of many highlights of the N99xxD-Sequence is ML-based sign classification that permits automated identification, a characteristic that may be unlocked when paired with Keysight Spectrum Administration Software program.
“The system makes use of wideband IQ knowledge, high-resolution spectrograms, and pattern-recognition algorithms to differentiate sign sorts throughout 120 MHz of IQ bandwidth and cut back guide sorting and speed up classification selections. These machine studying instruments assist engineers lower by noise, determine interference sources quicker, and spend much less time manually reviewing advanced datasets,” she stated.
Right here’s the way it works. Because it captures knowledge from the surroundings, the data is fed into the Keysight Spectrum Administration Software program which permits RF engineers to categorise indicators, view occupancy and run superior IQ evaluation on the info.
Because the indicators are recognized, their sources are detected with built-in GPS-enabled route discovering and distant receiver management. Engineers can then deploy transportable take a look at websites or cellular items to observe, find, and mitigate interference.
The D-series includes 14 microwave and spectrum fashions masking as much as 54 GHz and assist for over 25 software-defined functions.
