en.Wedoany.com Reported - At IMS 2026, Keysight Technologies introduced two new signal analysis platforms—the XA5 and XA6 spectrum/signal analyzers—with enhanced performance in measurement speed, wideband analysis, dynamic range, and multi-channel capabilities for modern RF systems.

Applications Engineer Randy Becker demonstrated the Pro XA6 SA6320. The setup used a VXD signal generator with frequency coverage up to 54 GHz for an A/B comparison between the new XA6 and the previous UXA model. A 5 GHz FM signal was split and fed into both analyzers. Compared to the UXA, the XA6 showed significantly faster update rates on the display, reflecting improved processing speed. In the noise performance and dynamic range demonstration, with the signal generator turned off, the XA6 measured a displayed average noise level of approximately -148 dBm/Hz, while the UXA measured around -134 dBm/Hz, indicating enhanced capability for detecting low-level signals and improving in-channel measurement sensitivity. In 5G NR signal analysis, under a 3 GHz, 100 MHz carrier condition, the XA6 achieved an error vector magnitude (EVM) of approximately -57 dB with faster measurement update rates. Extending the setup to a 5G NR signal with 2 GHz bandwidth at 20 GHz, the XA6 achieved an EVM better than -42 dB (below 1%), outperforming the UXA, which remained above 1%. The XA6 updated results approximately every half second, while the UXA took several seconds per result, highlighting a significant improvement in real-time measurement capability. Designed for wideband and high-frequency analysis, the XA6 offers frequency coverage up to 67 GHz and analysis bandwidth up to 8 GHz, featuring a redesigned RF front end for faster sweep speeds and using server-class CPU and GPU architectures to accelerate data processing and display updates. The system also includes a full-band preselector and a wideband preamplifier.

Keysight Scientist and Principal Applications Engineer Osamu Kusano demonstrated the Expert XA5 SA6210A, focusing on high-speed measurement and multi-channel analysis. The system performed fast spectrum measurements with narrow resolution bandwidths, showcasing the ability to capture detailed signal characteristics without compromising measurement speed. In 5G NR signal analysis, the XA5 achieved an EVM of 0.2%, indicating accurate modulation quality measurement. Multi-channel performance was demonstrated through dual-channel phase-coherent measurements, supporting applications such as MIMO analysis and signal correlation. The demonstration also included cross-correlation measurements, AM-AM and AM-PM characterization of RF components, and simultaneous input and output measurement capabilities. Designed for high-speed RF testing and characterization, the XA5 offers frequency coverage up to 32 GHz and analysis bandwidth up to 2 GHz, featuring a high-speed architecture with a redesigned ADC and FFT processing chain, as well as a dual-channel receiver architecture supporting phase-coherent and multi-channel analysis.
