Keysight Technologies, Inc. (NYSE: KEYS) introduces the XR3, a low-profile 14-bit oscilloscope designed to increase measurement capacity in rack-based test systems. Occupying one rack unit (1U), the XR3 provides four-channel, mixed-signal measurement capability without the space, weight, and cabling required by traditional bench instruments.

The Keysight XR3 packs full oscilloscope performance, including 4 analog and 16 digital channels, into a single rack-unit footprint for high-density, multi-channel test systems.

The Keysight XR3 packs full oscilloscope performance, including 4 analog and 16 digital channels, into a single rack-unit footprint for high-density, multi-channel test systems.

As automated test systems used in aerospace and defense, manufacturing, and physics applications grow more complex, engineers need to pack more measurement and analysis capability into increasingly dense equipment racks. Test systems that once relied on a single bench oscilloscope now often require several instruments working in synchronization, and every additional unit takes up valuable space, adds cabling complexity, and introduces undesirable signal skew. Engineers building and using these systems have had to choose between the flexibility of a full-featured oscilloscope and the compact form factor needed for scalable, high-density applications.

The XR3 removes this trade off, by combining Keysight’s benchtop-class measurement performance with a compact, scalable architecture. Built around Keysight’s MegaZoom 5 custom application-specific integrated circuit (ASIC) and a 14-bit analog-to-digital converter (ADC), it delivers a 50-microvolt root mean square (µVrms) noise floor and an update rate of 1.3 million waveforms per second. Multiple instruments can be synchronized to integrate over 100 channels in a single system, while selectable bandwidths from 200 MHz to 1 GHz let engineers scale performance to the application, accelerating debug and reducing time to market.

Key benefits of the XR3 include:

  • Uncompromised performance: With 100 Mpts of memory per channel, the XR3 enables engineers to capture small signals and rare events. In addition, zoom, filters, zone triggering, and color grading testing all run in real-time on hardware, without decreasing XR3’s 1.3 million waveforms per second update rate.

  • Expanded synchronized channel capacity: An autosensing 10 MHz reference in/out synchronizes clocks and triggers across multiple units, enabling over 100 time-correlated channels in a single multi-blade system. Hardware based auto-sync, auto-discovery and auto-deskew remove complexity from the synchronization process, providing a simplified setup.

  • Improved test system integration: Native software for protocol decodes, power supply test, and jitter analysis covers everyday debug needs. Infiniium 2026 software, native to the XR8 oscilloscope, can also run on an external controller as a unifying user interface to visualize and control multiple XR3 units from a single screen. Separately, the XR3 can be paired with Keysight’s next-generation XR8 oscilloscope to add low-noise, cost-effective high-impedance (Hi-Z) channels without the need to convert to a high-speed channel using an adapter.

Jun Chie, Vice President, Keysight Product Management, said: “Engineers building dense test systems should not have to choose between measurement performance and rack space. The XR3 brings benchtop-class capabilities to a compact, scalable platform, helping customers add synchronized channels, simplify integration, and preserve measurement confidence as their systems grow.”
