The latest additions to LeCroy Corp.’s WaveMaster range of oscilloscopes provides up to 45 GHz of bandwidth and 120 GS/s of sample rate combined with 768 Megapoints of analysis memory.
The 8 Zi-A Series includes a model with 20 GHz of true analog bandwidth on four channels and on all the 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 standard sample rate is 120 GS/s for 45 GHz bandwidth, 80 GS/s for 25 to 30 GHz bandwidths, and 40 GS/s on all 4 channels at 20 GHz bandwidth. For 4 to 20 GHz bandwidths, the standard sample rate is 40 GS/s on all four channels with an option to increase the sampling rate to 80 GS/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 GS/s mode, memory can be interleaved to 768 and 512 Mpts/ch.
The WaveMaster 8Zi-A models uses second generation silicon germanium (SiGe) components to improve performance and the 30 to 45 GHz 8Zi-A models make use of sixth generation digital bandwidth interleave (DBI) to effectively and reliably extend bandwidth.
LeCroy has designed the 8 Zi-A Series as a single hardware platform, supporting nine models spanning from 4 to 45 GHz of bandwidth. Engineers can upgrade to additional bandwidth as needs change. Customers who had previously purchased an 8 Zi model can upgrade to 8 Zi-A performance and bandwidth.
The WaveMaster 820Zi-A model provides four channels at 20 GHz with bandwidth out to 20 GHz and total jitter noise floor of <190 fs rms.
In addition to the 45 GHz capability, the 845Zi-A model may also be operated in a 30 GHz / 2 channel or a 20 GHz / 4 channel mode. This gives flexibility to utilize multiple channels at 30 GHz or 20 GHz for timing validation while utilizing fewer channels for high bandwidth signal fidelity measurements. Jitter noise floor at 45 GHz is 125 fs rms.
Maximum sample rate in single channel mode is 120 GS/s (45 GHz), with 80 GS/s and 40 GS/s operation in 2 channel (30 GHz) and 4 channel (20 GHz) modes respectively. Likewise, maximum analysis memory available is 768, 512, or 256 Mpts/ch in 45, 30, and 20 GHz modes respectively.
WaveMaster 8 Zi-A has additional processing power that augments the X-Stream II Streaming Architecture. The use of a IntelCore2 Quad processor rated at 3 GHz (with an effective 4 x 3 GHz = 12 GHz processing speed), 8 GB of RAM, and Windows 7 64-bit OS is standard. X-Stream II technology enables high throughput of data – even when the oscilloscope is analyzing 768 Mpt waveforms, by using variable waveform segment lengths to improve CPU cache memory efficiency resulting in 10 to 20 times faster processing compared to other oscilloscopes.
The processor is 20 percent faster than before, and standard memory on all 8 Zi-A oscilloscope models has been increased from 10 Mpt/Ch to 20 Mpt/Ch, and from 20 Mpt/Ch to 32 Mpt/Ch on the SDA models. The highest bandwidth SDA 845Zi-A model is standard with 96 Mpt/Ch of memory at 45 GHz.
The Jitter Timing and Analysis (JTA2) toolkit and XDEV Advanced Developer’s Toolkit are now standard in the 8 Zi-A models. The JTA2 toolkit contains several powerful tools, such as Track, that provides a graphical plot of a measurement parameter versus time, and histogram, that provides a graphical statistical view of measurement statistics. Track is useful to understand measurement or jitter parameter variations over time. Track can be used to the full record length of the oscilloscope, allowing millions of measurements to be measured and graphed over very long periods of time.
The XDEV Advanced Developer’s Toolkit allows customized integration by permitting an engineer to create and run custom math and measurement algorithms written in MATLAB, C/C++, Excel, Visual Basic Script (VBS) or JAVA script to be inserted into the oscilloscope processing stream with a result returned on the oscilloscope display and available for further analysis and processing.
For serial data applications, nine new Serial Data Analyzer (SDA) models from 4 to 45 GHz with similar sample rate, and analysis memory capability 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.
LeCroy’s advanced SDA II Serial Data Analysis software provides the ability to analyze and debug jitter problems utilizing unique and more precise measurement and analysis tools for both eye diagram and jitter decomposition. Eye diagram analysis enables nearly 1 million unit intervals of PCI Express can be captured, analyzed, and displayed in 3 seconds.
At the compliance stage, automated QualiPHY packages are available for a variety of established standards, such as USB3, PCIe, SAS, SATA, DDR, HDMI, and DisplayPort.
LeCroy’s Eye Doctor II signal integrity tool kit provides capability for cable and test fixture de-embedding, modeling of pre-emphasis and de-emphasis, serial data channel emulation, and serial data receiver equalization. It is now possible, within the scope environment and on full record lengths, to compensate for or emulate signal path effects and serial data receiver equalization so as to precisely measure waveforms with the highest signal fidelity at any place in the test circuit under any test condition.
LeCroy provides a range of high bandwidth probes and differential amplifiers up to 25 GHz of bandwidth. The WaveLink 13-25 GHz Differential Probes are available in 13, 16, 20, and 25 GHz models with browser positioner tip and solder-in lead, and are distinguished by the highest bandwidth solder-in lead (25 GHz), low noise, and high mid-band impedance.
