SANTA CLARA, Calif., July 29, 2013 — Agilent Technologies Inc. has introduced the M8061A, a 28.4-Gb/s multiplexer with optional de-emphasis for R&D and test engineers who need to characterize receivers for next-generation servers, storage systems and data-center networks. The device delivers accurate and repeatable receiver characterization results because of built-in eight-tap de-emphasis, which allows engineers to emulate transmitter de-emphasis and channels and compensate losses in the test setup. It is transparent to jitter from J-BERT and provides additional clock/two jitter injection capabilities. The built-in superposition of level interference eliminates the need for external power splitters that can cause level and signal degradations. The system allows engineers to characterize next-generation computing buses operating above 14 Gb/s and data-center input/output. When used with the J-BERT N4903B, loopback training sequences can be generated. The DC-coupled output enables unbalanced bit patterns without level drift, and the device can be switched to an electrical idle state for computer bus receiver tests, such as those required for PCI Express.
