This Application Note:
• Gives a brief orientation on the physical layer and packet structure of Ethernet, with a goal of providing just enough detail to help with troubleshooting
• Explains how to set up decoding on an oscilloscope equipped with Ethernet decoding
• Explains how to interpret serial bus data on an oscilloscope equipped with Ethernet decoding
• Explains what triggering and searching options are available on an oscilloscope with Ethernet analysis tools
With the optional serial triggering and analysis capability, Tektronix oscilloscopes become power tools for embedded system designers working with Ethernet buses. In this application note, the 5 Series MSO is used to demonstrate Ethernet serial bus decoding and triggering.
