Specifications

SATA-IO Confidential 53
See section 7.4.10 of Serial ATA Revision 2.6.
Measurement Requirements
Calibrate to the end of the SMA cables, but do NOT include (de-embed) the SMA to SATA PCB and the
SATA connector, so the board and the SATA connector are INCLUDED with the product measurement.
This test requirement is only applicable to products running at 1.5Gb/s. For products which support 3Gb/s,
this test is not required.
Testing of this requirement must be completed during transmission of the Mid Frequency Test Pattern
(MFTP), The amplitude of a TDR pulse or excitation applied to an active transmitter shall not exceed
139mVpp (-13.2dBm 50 ohms) single ended.
RL
DD11,TX
measured per the values in Table 5 (for products running at 1.5Gb/s)

2.14. Phy Transmit Signal Requirements
During the testing execution for all TSG test requirements, it is essential that the product under test be able to
complete an initial OOB sequence through the device COMWAKE prior to transmission of a BIST FIS or initiation of
the BIST mode sequence. This is to allow product calibration to occur prior to and/or during the initial power on and
detect sequences.
Tester must save all the calibration data (i.e. screen shot) that is done daily at a minimum, if not every device
evaluation. Valid calibration data must be available per product for review, even if the same calibration data (i.e.
daily) is used for multiple products. It is required that calibration be completed for this area of testing to ensure
consistent measurements and environment impacts.

2.14.1.1. Device/Host Expected Behavior
See section 7.2.2.3.1 of Serial ATA Revision 2.6.
See section 7.4.4 and section 7.4.2.1 of Serial ATA Revision 2.6.
Measurement Requirements
For products which support 3Gb/s, this requirement must be tested at both interface rates (1.5Gb/s and
3Gb/s).
For the interests of the Interoperability Program, the measurements will only be taken to verify this
requirement at the minimum limit. Within the specification, there are two options for measuring the minimum:
o Vtest = min(DH, DM, VtestLBP)1.5Gb/s [TSG-01a], 3 Gb/s [TSG-01g]
