LeCroy launches 65GHz oscilloscope on the road to 100GHz

LeCroy Corp. has unveiled a 65GHz LabMaster 10 Zi oscilloscope, a step up from the company's 60GHz LabMaster 10 Zi, as it announced plans to release a 100GHz version in 2013.

The improvement to 65GHz is made possible by the company's 8HP SiGe chipsets which can obtain 36GHz on four channels.

LeCroy's 65GHz model and 100GHz plans are implemented with LeCroy's patented DBI technology path. Also, LeCroy's proprietary ChannelSync architecture in the LabMaster 10 Zi oscilloscopes permits synchronization of up to eighty silicon-based 36GHz/80GSps channels and up to forty 65GHz/160GSps DBI channels.

The LabMaster features a modular oscilloscope architecture that 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 36GHz performance with up to 65GHz on two channels (and future upgrade to 100GHz on one channel). One LabMaster 10 Zi Master Control Module and one LabMaster 10 Zi Acquisition Module function as a single, conventional four channel 36GHz oscilloscope, or as a conventional two-channel 65GHz and four-channel 36GHz 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 36GHz and forty channels at 65GHz. A newly announced expansion module for LabMaster oscilloscopes provides the capability to quadruple the total number of acquisition modules and channels compared to before.

Modular design advantages
The LabMaster ChannelSync architecture advantages are numerous. There is a single sample clock and trigger circuit utilized by all acquisition modules to provide the highest acquisition precision possible for up to eighty channels. The modular design is "plug-and-play", so no programming, external clocking, clock synchronization, or complex connections between oscilloscopes are required. There is a single display and a single server-class (12-core) CPU in the MCM-Zi Master Control Module. All acquired channels and processed waveforms from all acquisition modules are displayed in one location for ease of use and understanding of informationjust like in a single, conventional oscilloscope. The entire connection and setup of multiple oscilloscope acquisition modules, including fine deskew calibration, takes approximately five to ten minutes. Nothing could be simpler.

LeCroy has announced a 28Gbit/s serial pattern trigger with support for up to 80bit non-return to zero (NRZ) serial patterns, 8b/10b and 64b/66b symbols, and PCIe Generation 3.0 protocol. This is in addition to the previously announced 14.1Gbit/s serial trigger with identical NRZ, symbol and protocol support. Both of these are true-hardware FPGA-based triggers that provide real-time monitoring of the acquisition stream and capture specific serial data traffic as defined by the user. This trigger significantly enhances the value of LabMaster 10 Zi for high speed serial data debugging by providing the ability to isolate errors to specific bit patterns or symbols and is more sophisticated and useful compared to a "software-trigger" that is provided by other manufacturers.

The oscilloscopes have the ability to display eye diagrams, histograms, bathtub curves, jitter measurements, etc. on four lanes simultaneously with reference/compare capability. These capabilities have been beta-tested and will be available to customers in July 2012. These capabilities are suited for customers that need four lanes of electrical serial data, such as 40GbE (4 x 10Gbit/s) or 100GbE (4 x 25Gbit/s or 28Gbit/s) and the ability to visually assess multiple lanes simultaneously for crosstalk infringement, measure amplitude noise at specific sampling points in the unit interval, and then perform subsequent analysis on crosstalk root cause. A LeCroy LabMaster 10 Zi system with four channels at 65GHz (two acquisition modules) will provide the ability to view two lanes simultaneously using cabled inputs and capture serial data signals with power spectral density to nearly the fifth harmonic, or use eight channels at 36GHz to capture all four lanes for detailed crosstalk analysis.

Coherent MIMO transmission
While DP-QPSK and 16-QAM modulation formats have garnered most of the research investments for optical transmission in the past few years, parallel optical systems, such as frequency-parallel coherent optical super-channels or spatially-parallel coherent optical multiple-input-multiple-output (MIMO) systems have been gaining attention due to their ability to scale fiber capacities and to obtain higher transmission rates with lower speed components. In recent MIMO experiments done at Bell Labs, a LabMaster 9 Zi-A modular oscilloscope with twelve channels was utilized to demonstrate a mode-multiplexed 6 x 20-GBaud QPSK transmission (240Gbit/s per wavelength channel) up to 4200km.

Also, researchers at Bell Labs have also used LabMaster oscilloscopes for QPSK and 16-QAM research at data rates approaching 1Tbps, most recently a 640Gbit/s single-channel line rate using 80GBaud PDM-16QAM.

The LabMaster 10 Zi product line consists of core four-channel 36GHz modules with bandwidth up to 65GHz available. The 65GHz LabMaster 10 Zi acquisition module is priced at $355,000, and a complete two channel at 65GHz and four channel at 36GHz LabMaster oscilloscope is priced at $451,900. LeCroy expects to begin customer shipments of LabMaster 10 Zi products in 2H 12.
