OCTOBER 4, 2010 -- LeCroy Corp. says its new line of WaveMaster 8Zi-A digital oscilloscopes, serial data analyzers, and disk drive analyzers -- the 8 Zi-A Series -- now provides up to 45 GHz of bandwidth and 120 Gsamples/s of sample rate, as well as 768 megapoints of analysis memory.
Additionally, the introduction of a model with 20-GHz bandwidth on four channels provides the highest performance and signal fidelity available on four measurement channels, LeCroy asserts. On all models, acquisition capability can be doubled with the use of the Zi-8CH-SYNCH Oscilloscope Synchronization Kit, with all acquired channels displayed on a single display grid.
The 20 GHz bandwidth on each of the four channels makes the WaveMaster 8 Zi-A Series well suited for testing emerging 40/100 Gigabit Ethernet (GbE) DWDM devices and systems, LeCroy says. It can be part of an optical dual-polarization quadrature phase shift-keying (DP-QPSK) test system for measuring 100+ GbE, and to measure the electrical properties of multi-lane 40/100-GbE transmissions. The WaveMaster 8 Zi-A Series can also be used in 224+ Gbps (56+ Gbaud) DP-QPSK, 16-QAM optical transmission research.
The standard sample rate is 120 Gsamples/s for 45 GHz bandwidth, 80 Gsamples/s for 25 to 30 GHz bandwidths, and 40 Gsamples/s on all four channels at 20 GHz bandwidth. For 4 to 20 GHz bandwidths, the standard sample rate is 40 Gsamples/s on all four channels with an option to increase the sampling rate to 80 Gsamples/s on two channels. All memory is available at full record lengths for analysis processing, 20 Mpts/ch is provided standard, with memory options up to 256 Mpts/ch available. In 120 and 80 Gsamples/s mode, memory can be interleaved to 768 and 512 Mpts/ch.
LeCroy’s 30 to 45 GHz 8Zi-A models make use of sixth generation Digital Bandwidth Interleave (DBI) to effectively and reliably extend bandwidth without the deleterious effects of bandwidth “boosting.”
LeCroy has designed the 8 Zi-A Series as a single hardware platform, supporting all nine models spanning from 4 to 45 GHz of bandwidth. This means engineers can leverage their investment and stay current with emerging high-speed technologies and serial data standards by purchasing only the bandwidth needed for current designs, and upgrading to additional bandwidth as needs change, the company says. Customers who had previously purchased an 8 Zi model can upgrade to 8 Zi-A performance and bandwidth.
In addition to the release of the WaveMaster 8 Zi-A oscilloscopes, LeCroy also announced LabMaster, a new family of high-speed, multi-channel oscilloscope modules. LabMaster provides up to five synchronized channels with 45 GHz of bandwidth, up to 10 synchronized channels with 30 GHz of bandwidth, and up to 20 synchronized channels of up to 20 GHz of bandwidth. This new offering is aimed at designers of emerging high-speed multi-lane data communications systems.
WaveMaster 8 Zi-A deploys second generation silicon germanium (SiGe) chipsets to provide improved performance. Aside from increased bandwidth (20 GHz on four channels, mentioned earlier), the new second generation chips provide improved signal to noise performance of approximately 25% and establish a new performance baseline, particularly in the 820Zi-A (4 channel at 20 GHz) model.
Lastly, two distinguishing features of LeCroy oscilloscopes, the Jitter Timing and Analysis (JTA2) toolkit and our XDEV Advanced Developer’s Toolkit are now standard in the 8 Zi-A models.
Serial Data Analyzers
For serial data applications, nine new Serial Data Analyzer (SDA) models are designed to provide the same high bandwidth range (from 4 to 45 GHz), sample rate, and analysis memory capability (with 32 Mpts/ch standard), and are combined with LeCroy’s SDA II Serial Data Analysis tools and standard serial trigger to provide unmatched capability for implementing and debugging emerging, high-speed serial data standards, such as PCIe 3.0 and USB 3.0.
Delivery on 4 to 30 GHz Wavemaster 8 Zi-A, SDA 8 Zi-A, and DDA 8 Zi-A Models is 4-6 weeks ARO
Delivery on 45 GHz WaveMaster 8 Zi-A, and SDA 8 Zi-A Models is 20 weeks ARO
