Introducing the Keysight XR3: More Channels. Less Space. Perfectly Synchronized.

 

Discover the new 14-bit InfiniiVision XR3 oscilloscope, combining high-resolution measurements, a compact 1U rack design and scalable multi-scope synchronization.

As automated test systems become more sophisticated, engineers face a growing challenge: capturing more signals, synchronizing more channels and maintaining measurement accuracy without increasing rack space and system complexity.

The new Keysight InfiniiVision XR3 Low Profile Oscilloscope addresses these challenges with a compact, high-performance measurement platform designed for modern automated test environments.

With four analog channels, 16 digital channels, 14-bit resolution and the ability to synchronize more than 100 channels across multiple instruments, the XR3 brings advanced oscilloscope capabilities into a space-saving 1U rack-mountable design.

 

High performance in just 1U of rack space

Traditional benchtop oscilloscopes deliver powerful measurement capabilities, but integrating multiple instruments into automated test systems can quickly consume valuable rack space.

The Keysight XR3 changes this approach.

Its low-profile 1U design enables engineers to increase measurement channel density while maintaining the performance expected from a full-featured oscilloscope.

 

Key technical highlights:

  • 14-bit ADC resolution for detailed signal measurements
  • 200 MHz to 1 GHz bandwidth to accommodate different applications
  • 4 analog and 16 digital channels per instrument
  • Up to 3.2 GSa/s maximum sample rate
  • 100 Mpts memory per analog channel for capturing longer signal sequences
  • 1.3 million waveforms per second update rate for detecting rare events
  • 50 µVrms noise floor for precise low-level signal measurements
  • 1U rack-mountable design for high-density automated test systems

Powered by Keysight's MegaZoom 5 ASIC, the XR3 combines advanced acquisition performance with hardware-accelerated analysis features.

 

Scale beyond 100 synchronized channels

One of the most significant capabilities of the XR3 is its multi-oscilloscope synchronization architecture.

Modern validation and automated testing frequently require engineers to observe dozens or even hundreds of signals simultaneously. Synchronizing multiple independent oscilloscopes can introduce complexity, timing differences and additional setup effort.

The XR3 simplifies this process.

Using an autosensing 10 MHz reference clock and hardware-based synchronization, multiple XR3 instruments can operate as a coordinated measurement system.

Automatic synchronization, instrument discovery and deskew help engineers build larger, time-correlated measurement configurations with less manual setup.

The result: scalable systems with more than 100 synchronized channels, enabling engineers to analyze complex signal relationships with greater confidence.

 

Capture small signals and rare events with confidence

Measurement accuracy becomes especially important when analyzing low-amplitude signals, power supply noise or intermittent faults.

The XR3 combines a 14-bit analog-to-digital converter with a low-noise front end to reveal signal details that might otherwise be difficult to distinguish.

Its 50 µVrms noise floor supports precise low-level measurements, while the acquisition system processes up to 1.3 million waveforms per second.

Hardware-accelerated features, including zone triggering, filtering, zoom and color grading, allow engineers to investigate signal behavior without reducing the specified waveform update rate.

Combined with 100 Mpts of memory per channel, these capabilities help engineers identify rare glitches, investigate transient events and troubleshoot complex electronic systems.

 

Designed for automated test environments

Beyond measurement performance, the XR3 is engineered for integration into automated and scalable testing architectures.

Native software capabilities support common engineering workflows, including protocol decoding, power supply testing and jitter analysis.

For more complex systems, Keysight's Infiniium 2026 software can run on an external controller, providing a unified interface for visualizing and controlling multiple XR3 instruments.

The XR3 can also complement Keysight's high-performance XR8 oscilloscopes by adding low-noise, high-impedance measurement channels.

This flexibility makes the XR3 an attractive solution for applications where measurement performance, channel scalability and efficient system integration are equally important.

 

Where does the XR3 make a difference?

The new oscilloscope is particularly suited to engineering environments requiring high channel counts and synchronized measurements.

Aerospace and defense

Capture and correlate multiple signals across complex electronic systems during development, integration and validation.

Automated manufacturing and production testing

Increase measurement density in test racks while supporting repeatable, automated test procedures.

Research and high-energy physics

Synchronize large numbers of measurement channels for experiments requiring precise signal correlation.

Electronics development and system validation

Analyze mixed analog and digital signals, investigate intermittent faults and build scalable validation environments.

 

A new approach to high-density oscilloscopes

The Keysight InfiniiVision XR3 represents an important step toward more compact, scalable and synchronized measurement systems.

Rather than choosing between rack space and oscilloscope performance, engineers can combine high-resolution signal acquisition with flexible, multi-instrument configurations.

For organizations developing advanced automated test systems, the XR3 offers a practical way to increase channel capacity while simplifying measurement integration.
