LeCroy's physical layer transmitter compliance test application for SAS-2

LeCroy has launched QualiPHY SAS-2, the first physical layer transmitter compliance test application for SAS-2, the latest generation of the Serial Attached SCSI standard. The release of this software expands LeCroy's portfolio of QualiPHY automated serial data compliance test solutions, providing automated control for the SDA 8 Zi series of oscilloscopes to test SAS initiators and targets running at 1.5 Gb/s, 3.0 Gb/s and 6.0 Gb/s. QualiPHY SAS-2 performs all transmitter physical layer tests in accordance with the UNH IOL Serial Attached SCSI (SAS) Consortium SAS-2 6Gbps Physical Layer Test Suite from Group 1 (TX OOB Signaling and AC Coupling Requirements), Group 2 (TX Spread Spectrum Clocking (SSC) Requirements) and Group 3 (TX NRZ Data Signaling Requirements).

SAS is the serialized version of the SCSI standard, and is primarily used for server class storage. With the release of the SAS-2 specification, the maximum speed of SAS increased from 3 Gb/s to 6 Gb/s to meet the increasingly high throughput demands of the storage industry.

In addition to automated compliance testing of SAS-2 signals, QualiPHY SAS-2 also enables powerful debug capability for SAS-2 signals inside the oscilloscope. All of the waveforms tested can be saved to easily share information or rerun the tests at a later time. Root causes of failure can be quickly and easily found using all of the advanced serial data tools within the oscilloscope. These include LeCroy's popular SDA II, Eye Doctor II, and WaveScan features.
