Keysight Launches Low-Profile XR3 Oscilloscope to Maximize Rack Test Density
Keysight Technologies has debuted the XR3, a 1U oscilloscope designed to increase measurement capacity in space-constrained rack systems. According to Engineering.com, the 14-bit instrument provides four-channel mixed-signal capabilities, allowing engineers in the aerospace, defense, and manufacturing sectors to scale their testing infrastructure without the physical footprint and cabling complexity of traditional bench-top hardware.
Context from Industry Pulse
The demand for high-density testing solutions is driven by the growing complexity of automated systems in the aerospace, defense, and physics sectors. As reported by Engineering.com, traditional bench instruments often create logistical hurdles in these environments due to their weight, size, and the signal skew introduced by complex cabling. The XR3 addresses these issues by offering a 1U form factor that integrates hardware-based synchronization. This allows for over 100 channels to operate in a single multi-blade system. By consolidating measurement capabilities into a smaller footprint, engineers can maintain high update rates and low noise floors while reducing the physical space required for comprehensive signal analysis and system debugging.
"The XR3 removes this trade off, by combining Keysight’s benchtop-class measurement performance with a compact, scalable architecture."
The introduction of the XR3 aims to solve a persistent bottleneck in automated test environments where increasing complexity requires multiple synchronized instruments. As Engineering.com reports, these systems often suffer from signal skew and excessive cabling when traditional units are stacked. The new low-profile architecture allows for a high-density configuration that maintains the performance metrics typically associated with larger benchtop models while fitting into a single rack unit.
Internal hardware specifications focus on high-fidelity signal capture. Engineering.com notes that the device is powered by the MegaZoom 5 custom integrated circuit and a 14-bit analog-to-digital converter. These components enable a noise floor of 50 microvolts root mean square and an update rate of 1.3 million waveforms per second. Furthermore, the unit offers 100 million points of memory per channel, which supports the detection of rare signal events and small fluctuations.
Scalability is a primary feature of the new system design. According to Engineering.com, multiple XR3 units can be synchronized to create a single system containing more than 100 time-correlated channels. This process is managed through hardware-based auto-discovery and auto-deskew functions, which utilize an autosensing 10-megahertz reference. The design allows engineers to adjust bandwidth from 200 megahertz up to 1 gigahertz depending on the specific requirements of the application.
Integration with existing software ecosystems further streamlines the testing workflow. Engineering.com indicates that the XR3 runs native software for jitter analysis and protocol decodes. It can also be controlled via an external interface through Infiniium 2026 software, which provides a unified view of multiple units. Additionally, the instrument can be paired with the XR8 oscilloscope to add cost-effective high-impedance channels to the test setup without requiring specialized adapters.
The Industry Pulse Bottom Line
The Keysight XR3 provides a scalable, 1U solution for high-density automated testing, delivering 14-bit resolution and synchronized multi-channel performance to reduce complexity and signal skew in aerospace and manufacturing environments.
