N8851A 100GBASE-KR/CR 64b/66b Solution with Link Training Decode Software

Product Status: Discontinued | Currently Supported
This product is no longer available

Key Features & Specifications

  • Set-up your oscilloscope to show 64b/66b decode in less than 30 seconds
  • Get 64b/66b decoder along with a link training decoder in one solution
  • Decode of 100GBASE-KR/CR links
  • Get detailed training frame information on control channels such as status update and coefficient update registers with Link Training Decode of Differential Manchester Encoding (DME)
  • Get access to a rich set of integrated protocol-level searches
  • Save time and eliminate errors by viewing packets at the protocol level
  • Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause
  • Includes PRBS polynomial lane identification decode


The N8851A 100GBASE-KR/CR is the only solution that combines both a 64b/66b decoder and a link training decoder. The N8851A enables engineers to decode 64b/66b data and link training data in less than 30 seconds. It includes a suite of configurable protocol-level searches and software-based triggering specific to 64b/66b and link training of Ethernet technologies such as 100GBASE-KR/CR. The link training signaling, also known as Differential Manchester Encoding (DME), provides detailed information on control channels such as status update and coefficient registers.

The multi-tab protocol viewer includes correlation between the waveforms and the selected packet, enabling users to quickly move between the physical and protocol layer information using the time correlated tracking marker. The 64b/66b and link training decoder is compatible with 100GBASE-KR/CR.

The N8851A is compatible with Keysight V-Series and Z-Series oscilloscopes.
