The N4212A gigabit ethernet protocol analysis tool is optional software that adds protocol-based display and error detection capabilities to the logic analyzer. This tool helps you look at data traveling across gigabit ethernet TBI (Ten Bit Interface) buses in high level format. The tool decodes 8B/10B encoded data on the 10-bit parallel TBI data bus and creates protocol listings. It does not work with 10-bit buses whose data has already been decoded in hardware.

The gigabit ethernet protocol analysis tool decodes a number of pre-defined protocols (including most of the internet protocol stack). You can modify these predefined protocol definitions and add proprietary ones if necessary.

All TBI interface traffic is time-stamped in the logic analyzer for time-correlation measurements with other system buses such as a microprocessor, memory interface, network processors, etc.
