LeCroy says it's LabMaster 9 Zi-A Modular Oscilloscope System now provides higher bandwidth at the same channel density with the addition of a 36GHz Acquisition Module. The higher bandwidth is needed by customers performing optical coherent modulation analysis at data rates of 28+GBaud (112+Gb/s) or for 10 to 28Gb/s electrical non-return to zero (NRZ) serial data testing. Development and installation of systems using these data rates is being driven by trends in cloud computing and mobile device communication that are requiring more optical backhaul transmission bandwidth. The IEEE 802.3ba standard and Optical Internetwork Forum (OIF) recommendations for 100GbE are the technical drivers in these areas. The Acquisition Module can be configured in a LabMaster 9 Zi-A system to provide up to 10 channels at 36GHz and 20 channels at 20GHz, with analysis memory up to 512Mpts/ch. It is also backwards-compatible with LabMaster 9 Zi-A "Master" Acquisition Modules. Users needing even more bandwidth than 36GHz can purchase LabMaster 9 Zi-A Modular Oscilloscope Systems that provide up to five channels at 45GHz. The most popular system configuration for the acquisition module is likely to be a 4 channel x 36GHz system with 80GS/s per channel for acquiring the four tributaries of a DP-OPSK or 16-QAM optical coherent modulated transmission system.
