With high instrument responsiveness, 10 to 100 times faster analysis processing time, a large 15.3”, 16:9 high-definition touch screen display (50% larger than 12.4” displays), the precision of Eye Doctor signal integrity tools, and both 50/1 M input capability, the WaveMaster 8 Zi Series is the most versatile oscilloscope platform available. Features previously announced with the Zi platform, such as TriggerScanTM rare event capture, removable front panel, integrated second display, and fast LSIB external data transfer (up to 250 Mpts/s—25 to 50 times faster than any other method) are also available. The combination of performance, speed, precision, and capability provides engineers with deeper insight, faster debug, and more efficient validation.
The 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. This is an especially attractive feature in lean economic times, particularly with upgrades available to 30 GHz of bandwidth, as companies seek to minimize capital investments.
The standard sample rate is 80 GS/s for 20 to 30 GHz bandwidths (40 GS/s on all 4 channels at reduced bandwidth). For 4 to 16 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, 10 Mpts/ch is provided, with memory options up to 256 Mpts/ch available. In 80 GS/s mode, memory can be interleaved to 512 Mpts/ch.
For serial data applications, eight new Serial Data Analyzer (SDA) models provide the same high bandwidth range (from 4 to 30 GHz), sample rate, and analysis memory capability (with 20 Mpts/ch standard), and are combined with the company’s SDA II Serial Data Analysis tools and 3.125 Gb/s serial trigger to provide high capability for implementing and debugging emerging, high speed serial data standards, such as PCIe 3.0 and USB 3.0.
Superior SDA
SDA 8 Zi serial data analyzers are based on the WaveMaster 8 Zi Series oscilloscope and are equipped with double the standard memory to capture more unit intervals in the eye diagram. They include an enhanced high-speed serial pattern trigger that operates on up to 80 bit patterns and at speeds up to 3.125 Gb/s.
The expansive SDA II toolset includes superior jitter breakdown methodologies and more precise jitter breakdown tools to increase confidence in measurements, and offer more complete insight, faster than competitive tools. Eye diagram analysis can be accomplished 100 times faster than competitive tools, nearly 1 million unit intervals of PCI Express can be captured, analyzed, and displayed in 3 seconds. Additional tools, such as IsoBER and Mask Violation Locator make it easy to understand complex problems. The Cable De-Embedding feature allows cable distortion effects to be removed to achieve more accurate timing and amplitude measurements on high-speed eye diagrams. Complete, simultaneous views of eye diagrams, time interval error, bathtub curves, jitter histograms, and other jitter breakdown analysis is standard in the new SDA 8 Zi analyzers.
The company’s advanced SDA II tools simplify the path to compliance testing by decreasing debug time and increasing the understanding of jitter through superior and more precise analysis of Rj+Dj breakdown. At the compliance stage, automated QualiPHY packages are available for a variety of established standards, such as PCIe, SAS, SATA, HDMI, DisplayPort, and XAUI.
Eye Doctor Adds Precision to Signal Integrity Measurements
Oscilloscopes with bandwidths up to 30 GHz are needed to test the fastest emerging technologies in the most difficult measurement environments. Challenges that were not very pronounced at rise times of 50 ps, or bit rates of 2.5 Gb/s and slower, become more problematic as rise times approach or become less than 25 ps, and bit rates exceed 5 Gb/s. At these speeds, engineers face signal integrity problems that were formerly limited to the microwave frequency domain, such as imperfect test fixtures and test circuit connections.
The engineers also implementing the new high speed serial data standards are faced with the challenge of faster and more complex signals, while at the same time the serial data channel (interconnect, transmission line, backplane) speeds have not commensurately increased, leading to problems with signal degradation in the serial data channel. In addition, emerging serial data standards, such as USB 3.0, require simulation (emulation) of the signal transmission path to ensure reliable performance in all user environments. Lastly, serial data receiver hardware is specifically designed to equalize for signal degradation, yet engineers have no way of characterizing the performance of their measured signals with receiver equalization applied.
The solution is the company’s Eye Doctor signal integrity tool set that 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 256 Mpt 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.
Fast Throughput with X-Stream II Streaming Architecture
Designed for long memory operation and responsiveness X-Stream II technology enables high throughput of data, even when the oscilloscope is analyzing eight 256 Mpt waveforms. This architecture utilizes variable waveform segment lengths to improve CPU cache memory efficiency resulting in 10 to 20 times faster processing compared to other oscilloscopes. This eliminates the trade-offs between long memory length and quick processing. WaveMaster 8 Zi’s proprietary architecture design is augmented with an IntelCore 2 Quad processor, high-speed serial databuses, a 64-bit OS and up to 8 GB of processor RAM.
More Flexible and More Powerful Tools
The WaveMaster 8 Zi Series offers standard measure, math, graphing, statistical, frequency analysis, mask testing, and other tools, as well as more ways to leverage the tools to get answers faster. The WMZi-Spectrum option offers spectral analysis capability to measure power density, real, imaginary, and magnitude FFT types that emulate the operation of a spectrum analyzer. A table shows the peak spectra and levels for easy review. Parameter Math gives the fastest and most accurate calculations in an oscilloscope: 750,000 measurements per second. Parameters can be added, subtracted, multiplied or divided by any two standard or custom parameters. Eight Math/Zoom functions provide chained math on math operations. Only LeCroy integrates third party programs into the oscilloscope’s processing stream by allowing you to create and deploy a new measurement or math algorithm directly into the oscilloscope environment and display the result on the oscilloscope in real-time.
