Traffic volumes at data centers are exploding with the spread of cloud computing services. To solve this problem, new high-speed interfaces, such as 400 GbE and CEI-56G, are being explored to speed-up communications between servers and network equipments. The receiver characteristics and Jitter Tolerance are key performance indices of PHY devices, such as SERDES, used by these high-speed interfaces. Combining the 56G/64G bit/s MUX MP1861A and 56G/64G bit/s DEMUX MP1862A with an MP1800A with installed PPG, ED, and Jitter modulation source supports generation of serial NRZ data up to 64 Gbit/s, as well as BER and Jitter Tolerance measurements. The tolerance to various Jitter components, such as SJ, RJ, BUJ, SSC, Dual Tone SJ, Half Period Jitter (Even/Odd Jitter), can be measured along with Bathtub Jitter to support new standards, such as CEI-56G.
