Patent ID: 6973407

Claim:
A method for capturing data suitable for creating a Serial ATA eye diagram, comprising: powering up a Serial ATA host controller including a first Serial ATA port and a second Serial ATA port, receive lines of said first Serial ATA port being short-circuited to receive lines of said second Serial ATA port, said first Serial ATA port being communicatively coupled to a Serial ATA drive; receiving, by said first Serial ATA port and said second Serial ATA port, an initialization pattern from said Serial ATA drive; transmitting an ALIGN/SYNC pattern over transmit lines of said second Serial ATA port; and capturing data transmitted over said transmit lines of said second Serial ATA port using a high impedance differential probe and an oscilloscope, said transmit lines of said second Serial ATA port being connected to each other via a resistor, and said oscilloscope being communicatively coupled to said high impedance differential probe.
