Real-time oscilloscope hits 65 GHz bandwidth, 100 GHz target for 2013

May 21, 2012 // By Jean-Pierre Joosting
LeCroy Corporation recently extended the LabMaster 10 Zi product line to 65 GHz from a previously announced 60 GHz, and unveiled a roadmap to provide 100 GHz of real-time bandwidth in the LabMaster 10 Zi platform. The improvement to 65 GHz is made possible by outstanding results achieved with 8HP SiGe chipsets, which are performing beyond expectations.

The first 100 GHz real-time oscilloscope using LeCroy's patented Digital Bandwidth Interleave™ (DBI) technology will be available in calendar year 2013. This technology is used in the company's current product lines to achieve 45 GHz real-time bandwidth, and has been supplied to customers since 2010.

LeCroy's silicon bandwidth advantage is due to years of accumulated experience with widely adopted, mainstream, commercial SiGe processes. The company uses 8HP SiGe, the most recently available process, to obtain 36 GHz on four channels. The 65 GHz model and 100 GHz plans are implemented with the company's patented and proven technology path, DBI. Furthermore, the proprietary ChannelSync™ architecture in the LabMaster 10 Zi oscilloscopes permits precise synchronization of up to eighty silicon-based 36-GHz/80-GS/s channels and up to forty 65-GHz/160-GS/s DBI channels — with a future 100 GHz upgrade path.

Modular platform

The LabMaster modular oscilloscope architecture separates the oscilloscope signal acquisition function from the display, control, and processing functions. The LabMaster Master Control Module (MCM-Zi) contains the display, controls, ChannelSync architecture, and a powerful server-class CPU. LabMaster 10 Zi Acquisition Modules, provide silicon-based 36 GHz performance with up to 65 GHz on two channels (and future upgrade to 100 GHz on one channel). One LabMaster 10 Zi Master Control Module and one LabMaster 10 Zi Acquisition Module function as a single, conventional four channel 36 GHz oscilloscope, or as a conventional two-channel 65 GHz and four-channel 36 GHz oscilloscope. However, by using ChannelSync architecture, up to twenty LabMaster 10 Zi Acquisition Modules can be perfectly synchronized, thus extending the already unique channel density performance by a factor of twenty to achieve up to eighty channels at 36 GHz and forty channels at 65 GHz. A newly announced expansion module for LabMaster oscilloscopes provides the capability to quadruple the total number of acquisition modules and channels compared to before.

The LabMaster ChannelSync architecture advantages are numerous. There is a single sample clock and trigger circuit
