The Keysight InfiniiVision HD3 Series oscilloscope has four times the vertical resolution and half the noise of other general-purpose scopes, thanks to its 14-bit ADC and ultra-low noise front end. This enhanced performance allows you to analyze even the smallest signals in your designs with a high degree of accuracy.

Now you can extend your new HD3’s capabilities by choosing two free eligible software applications — up to a $5,500 USD value:

  • 100 MHz waveform generator: provide stimulus output of a variety of different waveform types to your device under test
  • Power analysis: analyze power supply input, output, switching, and frequency response with automated power characterization measurements
  • Quick jitter analysis: characterize the behavior or periodic signals and visualize using histograms, measurement trends, and measurement spectral views
  • USB analysis: trigger on, decode, and search USB 2.0 low-, full, and hi-speed, as well as USB PD
  • Embedded protocol analysis: trigger on and decode common serial buses used for embedded and mixed-signal designs, including I²C, SPI, and RS232 / 422 / 485 / UART
  • Automotive analysis: trigger on and decode common serial buses used for power train and body control and monitoring, including CAN, CAN FD, CAN XL, LIN, and SENT
  • Aerospace & defense analysis: trigger on and decode MIL-STD 1553 and ARINC 429 for debugging and conformance analysis
  • 100 Mpts per channel memory: capture signals over a longer period, without compromising sample rate
  • Enhanced security: apply more stringent security, including password protection and disabling non-volatile memory, USB and LAN ports, and firmware upgrades
