Signal Quality Analyzer/Emphasis Configuration Used to Conduct Physical Layer Tests on Cables to Ensure Compliance with Latest IBTA Specification.
Anritsu Company announces that its MP1800A BERT Signal Quality Analyzer (SQA) and MP1825B 4-tap emphasis were used by the InfiniBand® Trade Association (IBTA) in the 21st InfiniBand Compliance and Interoperability Plugfest recently held at the University of New Hampshire Interoperability Lab (UNH-IOL), in Durham, NH. The MP1800A/MP1825B configuration was used during the compliance portion of the plugfest, which created a technically sophisticated environment to determine if products were in compliance with InfiniBand architecture specifications, as well as other InfiniBand products.
"We only used high-speed specialty equipment during the plugfest to meet the 56 Gbit/s requirements of the latest InfiniBand specifications. The MP1800A and MP1825B were essential tools in testing both QDR and FDR Active InfiniBand cables. We thank Anritsu and all the other companies that helped make the 21st InfiniBand Compliance and Interoperability Plugfest a success," said Rupert Dance, co-chair of the IBTA CIWG.
The MP1800A, which has a wide 100 Mbit/s to 56 Gbit/s bandwidth, and MP1825B were used to conduct Limiting Active Time Domain Testing measurements on QSFP+ cables (AOC 14.0625G x 4-channel) in accordance with volume two of the IBTA specification, the physical layer. The test required the MP1800A to produce a jittered eye based upon an independent setting of SJ and RJ, as well as emphasis from the MP1825B to compensate for Data Dependent Pulse Width Shrinkage (DDPWS). The ability of the MP1800A/MP1825B configuration to conduct pre-emphasis and produce a mask-compliant eye at the output of a mated connector pair (MCB+HCB) was vital to the test. This capability was achieved because the MP1825B Emphasis supports easy changes to the pre-emphasis waveform amplitude, offset, and amplitude of each tap, for effective evaluation of the characteristics of high-speed interfaces, including InfiniBand.
"Anritsu has always been active in organizations that help in the advancement of technology. Our test instruments are designed to ensure the performance of the next generation of communications products. We hope to continue to work with the IBTA, as our MP1800A/MP1825B is a solution that was developed with high-speed technologies, such as InfiniBand, in mind," said Wade Hulon, Vice President and General Manager, Anritsu Americas.
