25 GHz, 80 GS/s, 2ch, 20 Mpts/Ch Digital Bandwidth Interleaved (DBI) Oscilloscope with 15.3" WXGA

Innovative, Superior, Upgradeable

LeCroy has broken bandwidth barriers by combining custom designed SiGe high-speed components with 5th generation Digital Bandwidth Interleave (DBI) technology to achieve unprecedented real-time oscilloscope performance: 30 GHz, 80 GS/s, and 512 Mpts/Ch Analysis Memory.

X-Stream II architecture provides 10–100x faster processing of long records, true 512 Mpts analysis memory, and instantaneous instrument responsiveness. When off-line data analysis is preferred, the LeCroy Serial Interface Bus (LSIB) provides up to 325 MB/s data transfer speeds. A 15.3" WXGA touchscreen display provides 50% more viewing area compared to other oscilloscopes in this class. Both 50 Ω and 1 MΩ inputs are standard on all oscilloscopes, as is support for all LeCroy probes (including passive probes) without the need for easy to lose external adapters or expensive power supplies.

• Test Fixture and Cable De-embedding
• Emphasis Emulation
• Serial Data Channel Emulation
• Receiver Equalization

Add precision to signal integrity measurements by allowing the subtraction of fixture effects, and the emulation of emphasis, serial data channels, and receiver DFE, FFE, and CTLE equalization effects while at the same time maintaining fast oscilloscope processing speed on unlimited record lengths. Re-capture design margin, better understand actual circuit performance, and perform compliance testing on emerging high-speed standards, such as PCIe Gen3, USB 3.0, SAS/SATA 6 Gb/s, that require emulation to ensure high field reliability and interoperability.

SDA II Serial Data Analysis Software provides the highest confidence for serial data testing. Eye diagram analysis provides 100x faster capture of unit intervals (UI) in the eye diagram, and is enhanced with superior eye diagram analysis tools, such as lines of constant bit error rate (IsoBER ) and mask violation locators. Superior jitter decomposition methodologies and analysis tools provides more ability to understand problem behaviors in serial data systems. X-Stream II architecture leverages the superior tools through 10–100x faster processing and complete analysis processing of full record lengths, providing more insight faster.

As memory and sample rate can be interleaved, so can bandwidth. Using high- performance microwave and RF technologies, and high-speed processors and digital signal processing (DSP), LeCroy intelligently operates high-speed analog components comfortably within their rated bandwidth range while providing twice the four channel bandwidth on two channels. This approach offers better signal fidelity compared to “stretching” of components beyond their rated bandwidth. Best Investment Protection

From the perspective of bandwidth, sample rate, processing speed, responsiveness, display size, and range of capability, the WaveMaster 8 Zi platform is clearly superior and will remain so for many years to come. With the widest bandwidth upgrade range, an engineer who is working on 2nd generation technologies today can confidently know that WaveMaster 8 Zi will support 3rd or 4th generation technology needs several years from now.

X-Stream II architecture enables high throughput of data—even when the oscilloscope is performing multiple 100 Mpts (or larger) waveforms. X-Stream II uses variable waveform segment lengths to enable all processing intensive calculations to take place in fast CPU cache memory, thus improving calculation speed and efficiency. The result—10–100x faster processing compared to other oscilloscopes.

X-Stream II essentially has no analysis memory length restrictions, regardless of analysis type, since the variable waveform segment length can always be limited to a size that can fit in CPU cache memory. Other oscilloscopes with conventional architectures cannot make this claim, and often have limitations on analysis memory of 5–20% the length of their acquisition memory under the best conditions.

By dynamically allocating buffers to maximize memory availability, the WaveMaster 8 Zi Series embodies the fastest front panel responsiveness. A built-in processing abort makes front panel control changes instant by stopping the current process and allowing new waveforms to be positioned or zoomed—all without a lengthy recalculation. Meanwhile, waveform previewing shows interim calculation results.

WaveMaster 8 Zi excels in the way it offers general purpose utility never before seen in oscilloscopes from 4 to 30 GHz. All WaveMaster 8 Zi oscilloscopes contain selectable 50 Ω and 1 MΩ input capability and can be used with any LeCroy probe—passive or active—without requiring external adapters or power supplies. Use the two inputs per channel as a built-in switch matrix.

Understanding the relationships between different signals is vital to fast debug. Only WaveMaster 8 Zi combines the best of general purpose oscilloscopes (low-speed serial triggers and decoders, mixed signal capability, high impedance probing) with specialized 50 Ω inputs. This provides ability to 100% correlate high bandwidth signal activities or problems to low-speed events, such as low-speed serial data control words, power supply noise, or parallel data transmissions. Supported serial standards are 8b10b, PCIe, PCIe 2.0, SAS, SATA, XAUI, I2C, SPI CAN, LIN, UART-RS-232, and FlexRay.

A full range of serial triggers (I2C, SPI, UART, RS-232, CAN, LIN, FlexRay) are available, providing capability to isolate events related to serial peripheral bus traffic. Most serial triggers contain powerful conditional DATA triggering to allow inclusion or exclusion of entire ranges of data values, which expedites understanding of how a range of serial bus traffic DATA values interact with other signals.

TriggerScan uses high-speed hardware triggering capability with persistence displays to capture only the signals of interest and provide answers up to 100x faster than other methods.

The best trigger won’t find all unusual events—a more powerful capability is sometimes needed. WaveScan provides the ability to locate unusual events in a single capture (i.e., capture and search) or “scan” for an event in many acquisitions over a long period of time. Select from more than 20 search modes (frequency, rise time, runt, duty cycle, etc.), apply a search condition and begin scanning. When an event is found, WaveScan highlights the error on screen and displays a table listing the errors.

LeCroy’s Serial Interface Bus (LSIB) option enables direct connection to the PCI Express® x4 high-speed data bus in the oscilloscope to enable data transfer rates up to 325 MB/s. All that is required is installation of an optional LSIB card in the oscilloscope and the corresponding host board (card) for desktop (laptop) PC in the remote computer. Data transfer is easily enabled through a supplied application program interface (API).

In addition to the general purpose WaveShape Analysis tools, application specific solutions are available for Serial Data Compliance, Embedded Design, Digital Design, and Automotive. These packages extend the LeCroy standard measurement and analysis capabilities and expand your oscilloscope’s utility as your needs change.
