Figure – 1 Example result showing the last vestige of the connector response (at 1.8 ns)
The test shall be performed on one end of the cable assembly, for each differential pair of the assembly.
After completing the common procedures (and before doing the measurement) the instrument rise time shall
be set or the results filtered for a minimum of 55 ps to a maximum of 70 ps (20-80%) system rise time. The
system rise time shall be set as close to 70 ps (20-80%) as practical.
Pass/Fail Criteria
For an internal SATA and eSATA cable:
• Common Mode Impedance 25 - 40 ohms
2.7.5. SI-05 : Differential Rise Time
2.7.5.1. Cable Assembly Expected Behavior
See section 6.5.1.1, Table 16 of the Serial ATA Revision 2.6 specification.
Measurement Requirements
• This test is normative for internal SATA cables and informative for eSATA cables.
• For an internal SATA and eSATA cable:
o See section 6.5.2.4, Table 21, Procedure P8 of the Serial ATA Revision 2.6 specification.
o The test shall be performed in one direction on the cable assembly, for each differential pair of the
assembly.
Pass/Fail Criteria
For an internal SATA cable:
• Maximum Rise Time 85 ps (20-80%)
For an eSATA cable:
• Maximum Rise Time 150 ps (20-80%)
