Troubleshoot and verify 8b/10b encoded signals with a real-time oscilloscope

Few serial technologies have become more widely adopted than 8b/10b coding, which is now used in standards like PCI-Express, Serial ATA, SAS, Fibre Channel, InfiniBand, FireWire, MIPI M-PHY, HDMI, DisplayPort, CIPRI, OBSAI, XAUI, USB3.0 and others. Therefore, any designer will eventually need the ability to efficiently analyze 8b/10b encoded signals using common instrumentation such a real-time oscilloscope. The intent …
