Tektronix, Inc.INTRODUCTIONThe tests contained in this document are organized in order to simplify the identificationof information related to a test, and to facilitate in the actual testing process. Tests are separatedinto groups, primarily in order to reduce setup time in the lab environment, however the differentgroups typically also tend to focus on specific aspects of device functionality.The test definitions themselves are intended to provide a high-level description of themotivation, resources, procedures, and methodologies specific to each test. Formally, each testdescription contains the following sections:PurposeThis document outlines precise and specific procedures required to conduct SATA IW1.1 tests. This document covers the following tests which are all Tektronix CSA8200based.PHY TRANSMIT CHANNEL REQUIREMENTS (TX: 1-6)PHY RECIEVE CHANNEL REQUIREMENTS (RX: 1-6)Notes:Peeling Algorithm developed by Prof. Tripathi at Oregon State University which unlayers thevarious reflections in the TDR waveform and therefore shows the true values at each pointwithout the distortions caused by the reflections.Rx/Tx measurements for both Devices and Hosts will benefit from the accuracy introduced byobserving Peeling on the raw TDR response. For this reason this methodology will be applied toall Impedance related measurements in this MOI.SATA Rx/Tx MOI Revision 1.1 ver 1.06
Tektronix, Inc.Initial Measurement SetupBefore connecting the measurement cables and adaptors perform instrument’s warm-up and compensation accordingthe user manual.Connect four high quality (rated up to 18GHz) SMA cables to the four channels of 80E04 modules and performdeskew procedure for acquisition channels and TDR steps according to procedure described in Appendix B. Notethat TX measurements require the attenuators connected between the TDR heads of Ch3 and Ch3, and SMA cables.Connect appropriate SATA adaptor to the SMA channels The pair should match within 2ps.Connect the PUT according to the Figure 1.1. Ch1 and Ch2 are connected to the RX, while Ch3 and Ch4 areconnected to the TX pair. Set 4000 acquisition points in the “Horizontal” menu of the oscilloscope and 300 averagesin Acquisition menu.Ch1 Ch2 Ch3 Ch4SATA ProductUnder TestFigure 1.1.
