Test TSG-01 - Differential Output Voltage
Purpose: To verify that the Differential Output Voltage of the Products Under Test’s (PUT’s) transmitter is within
the conformance limits.

Resource Requirements:
Same as for PHY-01, repeated here for convenience:
• Agilent DSAX93204A, DSAX92804A, DSAX92504A, DSAX92004A and DSAX91604A (32GHz,
28GHz, 25GHz, 20GHz and 16GHz bandwidth, 80GS/s per channel) or Agilent DSA91204A (12GHz
bandwidth, 40GS/s per channel)
• Agilent N5411B SATA Electrical Performance Validation and Compliance Test Software
• Wilder Technologies SATA Gen3 Receptacle Adapter SATA-TPA-R or ICT-Lanto SATA Receptacle
Gen 3 TF-1R31 or Crescent Heart Software TF-SATA-NE/ZP or TF-eSATA-NE/ZP test adapter or
equivalent
• Gen2i capable products PC running ULink, SerialTek BusMod BusGen BIST Generator or any other
mechanism that makes the products produce the required patterns is acceptable.
See appendix A for details.

Discussion:
Reference [1] specifies the Transmitted Signal conformance limits for SATA products. This specification
includes conformance limits for the Differential Output Voltage. Reference [2] provides the definition of this term
for the purposes of SATA testing. Reference [3] defines the measurement requirements for this test.
Vdiff Min is tested with HFTP, MFTP and LBP. Vdiff Max is tested with MFTP and LFTP.
For products which support 3Gb/s or 6Gb/s, this requirement must be tested at both 1.5Gb/s and 3.0Gb/s
interface rates. Separate tests for 6Gb/s Max Amplitude and 6Gb/s Min Amplitude are defined in TSG-014
and TSG-015, respectively.
Test Setup:
1. Since PHY-01 the products has been producing HFTP and it is already connected to the scope. The
N5411B SATA compliance software will prompt for MFTP, LBP and LFTP when it needs those patterns.
When prompted, follow the procedures in reference [5] to activate those BIST-TAS patterns. Or keep
products in BIST-L.
2. Plug the test fixture into the products. The test fixture is connected to channels 1 and 3 of the scope by
two 36” SMA cables (Rosenberger or equivalent). OBSERVE the signal on the scope. If it is correct, press
OK in the N5411B prompt. If not, the products did not properly handle BIST Activate FIS; a non-standard
way to make it produce the desired pattern will be required.
Test Procedure:
This parameter is covered by Agilent Technologies, Inc. N5411B automated SATA compliance software,
revision 1.02 or later. Interim values for UH (HFTP upper), LH (HFTP lower), UM (MFTP upper), LM
