Test & Measurement: Protocol Analyzer Expanded To Support 4-Wide SAS Analysis

Built on the company's UPAS 10000 chassis, the SASTracer protocol analzyer has been expanded to support 4-wide serial attached SCSI (SAS) analysis, which is critical for testing 3-Gbit/s networks. The expanded SASTracer can simultaneously probe one, two, three, or four links and supports cooperative triggering and filtering across multiple links. Existing users of the $49,950 SASTracer system, which has two dual-port modules (four full-duplex links), can purchase an additional $18,950 module with ports 3 and 4 for 4-wide analysis. Version 1.01 software, free for current users, adds a Bus View that shows DWORD level traffic moving upstream/downstream on each link.
