Serial Number Port Tested Firmware Version Hardware Version Software Version UNH-IOL ID Number DUT: Reported Features DUT is a CT device DUT is an IT device that supports SATA DUT supports SSC on TX Test System Hardware Real-time DSO Sampling Scope MDI-to-SMA Adapter Vector Network Analyzer Additional Comments/Notes Agilent Infiniium DSO91304A, 13GHz, 40GS/s Real-time DSO Agilent DCA-J 86100C, with 86108B 50GHz Precision Waveform Analyzer Wilder Technologies SAS Receptacle Test Adapter Part No Agilent E5071C ENA S-Parameter measurements (Table 5, and Figures 19 through 30) were initially performed with the SAS mated connector pair included, and the TX and RX common-mode return loss results were both observed to be outside the conformance limits. (Note this is a common and expected problem, due to the common-mode characteristics of most SAS connectors.) The common-mode S-parameters were re-measured using timegating to remove the connector from the measurements. The eyemask used for 12G is informative. 3
