Automated scope software verifies SAS-3 conformance

Test & Measurement World Staff - August 9, 2012

Tektronix announced that its automated test software for SAS (Serial Attached SCSI) physical-layer conformance testing now includes measurement support for SAS-3 12-Gbps host and device interfaces. Using DPO/DSA/MSO70000 series oscilloscopes—with real-time sampling rates up to 100 Gsamples/s on two channels at 33-GHz bandwidth—along with DPOJET-based automated conformance test software, engineers can gain insight into critical SAS-3 design challenges.

Storage devices and chipsets operating at 12 Gbps introduce electrical design issues, such as crosstalk or reduced signal-to-noise ratio that previously could be ignored or resolved relatively easily. The Tektronix SAS-3 solution supports measurement of physical-layer design characteristics beyond conventional AC parametric measurements to include crosstalk and equalization analysis, along with integrated end-to-end simulation. The automation software also allows designers to troubleshoot design issues using DPOJET jitter and eye-diagram analysis tools.
