INTRODUCTION
The tests contained in this document are organized in order to simplify the identification
of information related to a test, and to facilitate in the actual testing process. Tests are separated
into groups, primarily in order to reduce setup time in the lab environment, however the different
groups 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 test
description contains the following sections:
Purpose
The purpose is a brief statement outlining what the test attempts to achieve. The test is
written at the functional level.
ReferencesThis section specifies all reference material external to the test suite, including the
specific subclauses references for the test in question, and any other references that might be
helpful in understanding the test methodology and/or test results. External sources are always
referenced by a bracketed number (e.g., [1]) when mentioned in the test description. Any otherreferences in the test description that are not indicated in this manner refer to elements within the
test suite document itself (e.g., “Appendix 6.A”, or “Table 6.1.1-1”)
Resource Requirements
The requirements section specifies the test hardware and/or software needed to perform
the test. This is generally expressed in terms of minimum requirements, however in some cases
specific equipment manufacturer/model information may be provided.
Last Modification
This specifies the date of the last modification to this test.
Discussion
The discussion covers the assumptions made in the design or implementation of the test,
as well as known limitations. Other items specific to the test are covered here as well.
Test Setup
The setup section describes the initial configuration of the test environment. Small
changes in the configuration should not be included here, and are generally covered in the test procedure section (next).
Procedure
The procedure section of the test description contains the systematic instructions forcarrying out the test. It provides a cookbook approach to testing, and may be interspersed with
observable results.

measured at the transmitter output. The test pattern used for this test is the High Frequency Test Pattern (HFTP).

1.5Gb/s).
Test Setup: See Appendix A
Test Procedure:
This test is included in the referenced SATA-IO MOI document. See Appendix B for details.
Observable Results:
The mean Unit Interval value shall be between 666.4333 ps and 670.2333 ps for 1.5Gb/s devices, and between 333.2167ps and 335.1167ps for 3.0Gb/s devices.
