Keysight InfiniiVision 4000 X-Series oscilloscopes are engineered for next-generation performance to deliver waveform update rates 20 times faster than the competition. A large 12.1-inch capacitive touch screen combined with innovative hardware-based zone touch triggering means you can easily capture and view your signals. Have confidence you will catch even the rarest of glitches and see more with the 4000 X-Series.

  • PathWave BenchVue oscilloscope software for remote control, data logging, and automated testing
  • Achieve 200 MHz to 1.5 GHz of bandwidth
  • See the most signal detail with 1,000,000 waveforms/second update rate
  • Isolate signals in seconds with zone touch triggering
  • Quickly test with a simplified operation and intuitive user interface enabled by a large 12.1-inch capacitive touch screen
  • Decode serial buses faster with hardware-based serial analysis options

PathWave BenchVue Oscilloscopes Software

Intuitively control your oscilloscopes, capture screen images, and log data measurements for more efficient analysis.

  • Connect and control your oscilloscopes through the cloud.
  • Export results in only three clicks to popular tools, such as MATLAB, Microsoft Excel, or Word for documentation or further analysis.
  • Visualize multiple types of instrument measurements simultaneously.
  • Create automated test sequences quickly with minimal instrument knowledge.
  • Receive KeysightCare software support subscription and license with each new instrument purchase.

Measure More Efficiently

A large 12.1-inch touch screen combined with many advanced capabilities ensures even deeper insight:

  • Turn the most advanced triggering into one easy step with zone touch triggering. Simply draw a box with your finger on screen
  • Get more out of your oscilloscopes with 7-in-1 instrument integration — oscilloscope, frequency response analyzer (Bode plots), logic analyzer / mixed signal oscilloscope (MSO), protocol analyzer, dual WaveGen (arbitrary waveform generator), voltmeter, and a frequency counter
  • Catch the rarest of glitches with a 1,000,000 waveforms/second update rate
  • Automate tests and collect data with the standard PathWave BenchVue Oscilloscope software
