60 GHz Real-Time Oscilloscope
LeCroy Corporation announces deployment of the highest bandwidth (36 GHz) and highest sample rate (80 GS/s) silicon technologies in the LabMaster 10 Zi oscilloscopes. This advanced new chipset represents technology capability well beyond that offered by other oscilloscope companies.When combined with LeCroy’s Digital Bandwidth Interleave (DBI) and LabMaster ChannelSyncTM architecture, it allows an unparalleled bandwidth density – five times more channels, more silicon-based bandwidth, nearly double the silicon-based bandwidth using DBI, and pricing comparable to oscilloscopes with far less capability.
The result is a number of industry firsts. Four oscilloscope channels, all at silicon-based 36 GHz bandwidth (the highest available) and 80 GS/s sample rate in a single acquisition module, provide twice the bandwidth density of competitive oscilloscopes.
LeCroy’s Digital Bandwidth Interleave (DBI) technology allows extension of the silicon-based 36 GHz bandwidth and 80 GS/s sample rate to 60 GHz and 160 GS/s by combining two 36 GHz channels. The 60 GHz real-time bandwidth is also an industry first, and is nearly twice the bandwidth rating of competitive 32 and 33 GHz oscilloscopes with an equivalent number of channels.
Futhermore, LeCroy’s Proprietary ChannelSync technology in the LabMaster 10 Zi oscilloscopes permits precise synchronization of up to twenty silicon-based 36 GHz / 80 GS/s channels and up to ten 60 GHz / 160 GS/s DBI channels??capability not offered by any other manufacturer, and an additional industry first. With this introduction, LeCroy definitively establishes its leadership position as the world’s preeminent supplier of ocilloscopes.
Performance Leadership in Every Possible Way
In addition to the industry leading bandwidth (60 GHz), sampling rate (160 GS/s), analysis memory (1024 Mpts/ch), high bandwidth channel density (four channels at 36 GHz in a single acquisition module), and channel count (up to ten channels at 60 GHz, up to twenty channels at 36 GHz), LabMaster 10 Zi also boasts a number of other industry firsts. Trigger bandwidth is 30 GHz – twice that of LeCroy’s WaveMaster8Zi-A and LabMaster 9 Zi-A oscilloscopes, and far more than is provided by competitive oscilloscopes. Jitter Noise Floor is an astonishingly low 100 fsrms for the 50 and 60 GHz models. Rise time (20-80%) is 5.5 ps for the 60 GHz model, and 9.75 ps for the 36 GHz model. Additionally, a 14.1 Gb/s 80-bit serial pattern trigger with support for 8b/10b and 64b/66b symbol triggering and PCI Express Generation 3.0 will be optionally available for LabMaster 10 Zi models. This trigger significantly enhances the value of LabMaster 10 Zi for high speed serial data debugging by providing ability to isolate errors to specific symbols and PCI Express link layer.
Key Technology Enablers
LeCroy’s silicon bandwidth advantage is due to years of accumulated experience with SIGe processes, most recently by obtaining 20 GHz of silicon bandwidth using 7HP SiGe. The new industry-leading LeCroy 36 GHz chipset is based on 8HP SiGe. SiGe is a widely adopted, mainstream, commercial process backed by chip technology leader IBM Semiconductor, with years of collective implementation knowledge and experience. IBM’s 8HP SiGe process is the fourth-generation SiGe process with two times the performance of the previous generation and up to 200 GHz transistor switching speeds. 8HP SiGe provides lower electrical noise for increased performance, which translates into a 3 to 4 dB baseline noise improvement compared to previously deployed 7HP SiGe. This equates to noise performance at 36 GHz, roughly equivalent to what is available in LeCroy or competitive 20 GHz oscilloscopes today. 8HP SiGe also provides lower power consumption, making possible a single acquisition module with twice the high bandwidth channel density available from other manufacturers.
DBI, a proprietary, patented LeCroy technology, provides the ability to double or triple the bandwidth available in raw silicon by splitting a high bandwidth signal into multiple paths of lower bandwidth, acquiring these lower bandwidth signals with best-in-class silicon chip technologies, and then re-assembling the separate lower bandwidth paths into a single high bandwidth path using digital signal processing (DSP). Sample rate and acquisition memory are likewise doubled or tripled along with the bandwidth. DBI is the only method that allows real-time oscilloscope bandwidth to go beyond the limits of what is possible with chip bandwidth alone, and is an absolute necessity for those customers who are testing leading-edge technologies. The 60 GHz LabMaster 10 Zi acquisition module utilizes 7th generation LeCroy DBI to nearly double the bandwidth of the four channel 36 GHz silicon-based acquisition module and provide two additional channels at 60 GHz, 160 GS/s, and up to 1024 Mpts/ch of analysis memory.
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, based on 8HP SiGe and DBI, provide silicon-based 36 GHz performance with up to 60 GHz on two channels. One LabMaster 10 Zi Master Control Module and one LabMaster 10 Zi Acquisition Module functions as a single, conventional four channel 36 GHz oscilloscope, or as a conventional two channel 60 GHz and four channel 36 GHz oscilloscope. However, by using ChannelSync technology, up to five LabMaster 10 Zi Acquisition Modules can be perfectly synchronized, thus extending the already unique channel density performance by a factor of five to achieve up to 20 channels at 36 GHz and 10 channels at 60 GHz.
Additional Models and Options
To meet a variety of industry needs, LeCroy is also announcing models with silicon-based 25 and 30 GHz of bandwidth, each with 80 GS/s sampling rate on each channel. A model with 50 GHz of bandwidth and 160 GS/s of sample rate on two channels is also available. This model also has silicon-based 36 GHz performance. All new acquisition module models are used with the LabMaster 10 Zi Master Control Module for easy expandability in channel count, and all models may be upgraded in bandwidth at a later date to up to 60 GHz. Customers who have made previous investments in LabMaster 9 Zi-A may mix and match those acquisition modules with the newly announced LabMaster 10 Zi models; preserving the customer’s previous investment in LeCroy oscilloscopes.
Standard memory is 20 Mpts/ch (on all four channels, doubled when channels are bandwidth interleaved) with memory options of 32, 64, 128, 256 and 512 Mpts/ch. Maximum analysis memory of 512 Mpts/ch (36 GHz) and 1024 Mpts/ch (60 GHz) is also an industry first, combining long acquisition captures with LeCroy’s strong heritage of long memory analysis capability and advanced eye diagram/jitter analysis with the worlds fastest and highest bandwidth density oscilloscopes.
The same software and hardware options , accessories, and probes available with the previous generations of LabMaster are also available with the LabMaster 10Zi.
LeCroy’s LabMaster 10 Zi provides four channels of silicon-based 36 GHz bandwidth in a single acquisition module at an attractive price point of $283,150 – twice the channels for the same price of competitive 32 or 33 GHz oscilloscopes. 36 GHz bandwidth provides sub 10ps rise time 20-80% measurement capability, near 100 fsrms jitter noise floor, capture of the fifth harmonic of 14.4 Gb/s serial data signals, and low noise performance. Four channels at maximum bandwidth provides the ability to debug crosstalk problems among multiple serial data lanes or from power distribution networks to a single serial data lane, or the ability to acquire both clock and data differential signals for serial data signals such as Quick Path Interconnect (QPI). At this price point, the silicon-based 36 GHz LabMaster 10 Zi is likely to become the new laboratory standard for high-speed SERDES measurements, replacing four-channel 20 GHz oscilloscopes in this application.
Cloud computing demands are driving rapid developments in buildouts of 28 GBaud (112 Gb/s) DP-QPSK optical coherent modulation systems. For 28 GBaud testing, a LabMaster 10 Zi silicon-based 36 GHz oscilloscope provides the most cost-effective, highest signal fidelity solution with low noise, again at a list price of $283,150, half of what competitors would charge for a two oscilloscope solution (four total channels at 32 or 33 GHz) that lacks the four channel phase accuracy of a LabMaster 10 Zi oscilloscope.
Used as the electrical signaling devices in the above mentioned 28 GBaud DP-QPSK systems, 28-32 Gb/s SERDES are accurately characterized for jitter with a two channel 50 GHz LabMaster 10 Zi system. These oscilloscopes offer far more bandwidth with the ability to capture beyond the third harmonic of 28 Gb/s NRZ signals at a price point, $365,900, only one third higher than competitive 32 or 33 GHz oscilloscopes. The customer can also purchase up to 60 GHz for this application and capture the fourth harmonic of these signals.
Research is already progressing on >56 GBaud (224 Gb/s) DP-QPSK and 16-QAM optical coherent modulation systems. LabMaster 10 Zi can be configured as a 2 to 4 channel 60 GHz system to allow research at the highest possible symbol rates, approaching 125 GBaud (500 Gb/s) for DP-QPSK or 1 Tb/s for 16-QAM. The industry-leading 160 GS/s sample rate will be highly appreciated for acquisition of high speed phase-modulated signals. List prices for 60 GHz LabMaster 10 Zi systems start at $411,900.
Lastly, optical transmission developments beyond 1 Tb/s will likely make use of lower data transmission rates but mode or frequency domain multiplexing, such as MIMO or OFDM, will require more than the four acquisition channels commonly provided in conventional oscilloscopes. LabMaster 10 Zi modular oscilloscopes provide up to 20 channels at 36 GHz or 10 channels at 60 GHz, thus making possible the development of advanced optical communication systems that would otherwise not be feasible.
LabMaster 10 Zi Pricing and Delivery
LabMaster 10 Zi oscilloscopes start at $252,900, with acquisition modules priced as low as $156,000. 36 GHz LabMaster oscilloscopes will be shown to customers in early 2012 with first shipments in the spring of 2012. First shipments of 50 and 60 GHz oscilloscopes will follow a quarter later.
