LeCroy: LabMaster 'Scope Now Has 36GHz Bandwidth
Modular lab oscilloscope system.
Chestnut Ridge, NY — LeCroy Corporation'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 new 36GHz capability — 20 percent more than previously offered by the company at this channel density — provides the most four-channel bandwidth in this class.

The higher bandwidth is desired by customers performing optical coherent modulation analysis at data rates of 28+ GBaud (112+ Gb/s) or for 10 to 28 Gb/s electrical non-return to zero (NRZ) serial data testing.

Development and installation of systems utilizing these data rates is being driven by trends in cloud computing and mobile device communications that are requiring more optical backhaul transmission bandwidth. The IEEE 802.3ba standard and Optical Internetwork Forum (OIF) recommendations for 100 GbE are the technical drivers in these areas.

The new Acquisition Module can be configured in a LabMaster 9 Zi-A system to provide up to 10 channels at 36GHz with 80 GS/s and 20 channels at 20GHz with 40 GS/s, with analysis memory up to 512 Mpts/ch. It is also backwards-compatible with previously purchased 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 with 120 GS/s.

The most popular system configuration for the new 36GHz system slave acquisition module is likely to be a 4-channel x 36GHz LabMaster 9 Zi-A Modular Oscilloscope System for acquiring the four tributaries of a DP-QPSK or 16-QAM optical coherent modulated transmission system. The additional bandwidth in a 36GHz LabMaster 936SZi-A compared to 30 or 32GHz solutions provides faster rise times, improvements in signal integrity measurements, and increased spectral content for I and Q eye diagram and IQ constellation diagram analysis, especially with systems utilizing additional Forward Error Correction (FEC) with 32GHz tributaries.

The ChannelSync architecture provides the extremely high phase stability necessary for accurate measurement of in-phase (I) quadrature (Q) phase shift keyed tributaries in DP-QPSK or 16-QAM optical transmissions where small phase errors can magnify into inaccurate representation of symbols in constellation diagrams. Such capability is obtained with two LabMaster 936SZi-A Slave Acquisition Modules and one LabMaster 9CZi-A Master Control Module.
