Modular scope provides up to 45 GHz, 120 GS/s, 20 channels

The LabMaster 9 Zi-A modular oscilloscope systems from LeCroy Corp. a bandwidth of 45 GHz, a sample rate of 120 GS/s, and up to 20 channels with analysis memory up to 768 Mpts/ch.

LeCroy says more ultra-high bandwidth oscilloscopes will be developed and deployed in the LabMaster 9 Zi-A family.

The LabMaster 9 Zi-A system architecture separates the oscilloscope signal acquisition function from the display, control and processing functions. The systems master acquisition modules contain the display, control, and a single acquisition module in one unit. Additional slave acquisition modules contain additional acquisition systems.

A server-class CPU is in a third module and the system uses ChannelSync technology so that the master acquisition module can synchronize slave  acquisition modules providing high channel density. The LabMaster 9 Zi-A design also allows users to configure systems for conventional benchtop use.

Adding additional acquisition modules, upgrading bandwidth on existing modules, or mixing and matching bandwidths can be done to upgrade a system. The platform even provides for future expandability as LeCroy introduces additional acquisition modules rated for higher bandwidth.

Each master or slave is available in bandwidth ratings of 13, 16, 20, 30, and 45 GHz with up to 256 Mpts/Ch of acquisition and analysis memory at up to 20 GHz, 512 Mpts/Ch at 30 GHz, and 768 Mpts/Ch at 45 GHz. Up to four slaves can be attached to one master, for a total of 20 channels at 20 GHz, 10 channels at 30 GHz, and 5 channels at 45 GHz.

By cabling signals into the scope instead of using a differential probe or amplifier, noise is decreased by 3dB or more, with higher user confidence in the overall signal fidelity of the complete measurement system.

The higher bandwidth (45 and 30 GHz) acquisition modules contain all of the bandwidth, sample rate and memory capability of the lower bandwidth modules.

The server-class CPU uses Intel Xeon X5660 processors (2.8 GHz per core, six cores per processor, and two processors per CPU = 33.6 GHz total effective clock speed) with 24 GB of RAM (192 GB optionally available) powers the LabMaster 9 Zi-A.

Waveforms are viewable on the built-in 15.3 inch display, or on a variety of optional or user-supplied displays (up to 2560 x 1600 resolution).

ChannelSync in LabMaster 9 Zi-A mimics the architecture of a single oscilloscope package, even though as many as 20 different channels can be synchronized. A single 10 GHz distributed clock signal is generated and used in the master acquisition module, and also distributed to as many as four additional slave acquisition modules.

The 10 GHz clock frequency – 1000 times faster than the 10 MHz reference clocks commonly used to synchronize lab equipment – ensures the high timebase accuracy and precise synchronization between all acquisition modules. The result is an ultra-low 275fsrms jitter between all channels.

Slaves are automatically identified to the master, and software automatically corrects for any static acquisition skew between all acquisition modules.

LabMaster 9 Zi-A is based on the acquisition and analysis technology used in the WaveMaster 8 Zi-A. Proven SiGe components ensure high performance with digital bandwidth interleaving (DBI) providing upgrade paths and bandwidth performance.

Nearly all software and hardware options available for the WaveMaster 8 Zi-A are also available for LabMaster 9 Zi-A.

LeCroy plans to announce additional LabMaster 9 Zi-A acquisition modules with highr bandwidth and channel density before the end of the calendar year.

LabMaster 9 Zi-A can be used to examine the technologies that provide enhanced high speed data transfer and communication – such as 28-32 Gb/s SERDES, multi-lane serial data (40/100 GbE, PCIe Gen3), and optical coherent modulation communications.  It is also suitable for defense and aerospace applications where high channel count and high bandwidth are both required.

LabMaster 9 Zi-A systems start at $135,000 with additional slave acquisition modules priced from $59,000.
