Teledyne LeCroy debuts WavePro HD oscilloscopes

May 8, 2018

Teledyne LeCroy today announced the WavePro HD high-definition oscilloscopes, which combine an 8-GHz bandwidth at 12-bit resolution with a 5-Gpoint acquisition memory in what Patrick Connally, technical marketing engineer, described as a scope lineup with industry-first acquisition capabilities. The new scopes, he added, provide full resolution at all sample rates and enable responsive operation. The instruments can acquire 250 ms of data at the full 20-GS/s sample rate to enable the capture of infrequent events.

In a recent phone interview, Connally cited key market trends driving the need for such instruments. Key applications in the electronics market today include mobile and handheld devices plus high-speed deeply-embedded computing systems, he said. Common characteristics for such applications include analog sensor inputs, sensitive power-distribution networks (PDNs), and high-speed CPUs and serial-data interfaces. He added that comprehensive debug of such systems requires a scope with high resolution and low noise, high analog bandwidth, long capture times, and a complete software toolset.

The new oscilloscopes build on Teledyne LeCroy’s HD4096 high-definition technology, which builds on 12-bit high-sample-rate ADCs, high SNR amplifiers, and a low-noise system architecture. Milestones for the company include the first 12-bit oscilloscope in 2011, a 12-bit scope with 1-GHz bandwidth in 2012, and a 12-bit, 1-GHz scope with eight channels in 2014.

The 8-GHz scopes introduced today include a new chipset with 12-bit, 20-GS/s ADCs and high-SNR 8-GHz front-end amplifiers. That chipset is tightly integrated with a new low-noise, high-bandwidth system architecture. Connally said competitive instruments either place a 10- or 12-bit ADC into a conventional 8-bit signal path or use software techniques to sacrifice bandwidth for higher resolution.

All WavePro HD oscilloscopes feature a 15.6-in., 1,900 x 1,080-pixel capacitive touchscreen, and Teledyne LeCroy’s MAUI with OneTouch user interface. The instruments come in four models with bandwidths from 2.5 GHz to 8 GHz, all featuring sample rates up to 20 GS/s.

In WavePro HD, high-resolution analog inputs may be combined with optional mixed-signal-oscilloscope (MSO) inputs for the capture of a range of analog sensor, digital-logic, power-rail, serial-data, and other signals. A full complement of standard analysis tools is augmented by serial-data Trigger, Decode, Measure/Graph, and Eye-Diagram (TDME) options. When combined with Teledyne LeCroy’s toolbox and toolsets for high-speed serial-data jitter analysis and protocol compliance, users have at their fingertips a debug and analysis solution for deeply embedded computing systems.

WavePro HD’s bandwidth and vertical resolution are suited for measurement and analysis of on-die and system PDN behavior. High bandwidth means accurate characterization of high-speed, on-die effects such as ground bounce, while WavePro HD’s dynamic range and 0.5% gain accuracy ensure confidence in sensitive measurements such as rail-collapse characterization. The low noise floor, combined with spectrum-analyzer software tools, helps extract and identify subtle PDN aggressors. The RP4030 4-GHz power-rail probe completes the WavePro HD’s power-integrity measurement capabilities with flexible connectivity options.

In the EMC lab, WavePro HD melds 2.5 or 4 GHz of bandwidth with high sample rates and resolution for accurate pulse characterization. On the test bench, system designers must discern EMI sources from within a dense electromagnetic landscape. WavePro HD’s low noise and intuitive spectral-analysis capability combine to yield a powerful interference-hunting tool.

For serial-data analysis, 12-bit resolution, a low noise floor, and low timebase jitter (60 fs) give the WavePro HD advantages in jitter and noise measurements. The optional SDAIII CompleteLinQ package comprises a set of serial-data jitter and vertical noise analysis tools, while optional QualiPHY serial-data compliance packages make easy work of physical layer validation.

WavePro HD also has a new 8-GHz, BNC-compatible ProBus2 probe interface. New 8- and 6-GHz ProBus2 probes connect directly to the WavePro HD, as well as to the 4-GHz ProBus interface on other Teledyne LeCroy oscilloscopes. In addition, ProBus-compatible probes also work with the new ProBus2 interface without adapters, ensuring compatibility with Teledyne LeCroy’s range of existing probes.

The WavePro HD is available now with pricing of $31,000 for the 2.5-GHz 254HD, $39,500 for the 4-GHz 404HD, $57,000 for the 6-GHz 604HD, and $71,000 for the 8-GHz 804HD. All are available in mixed-signal versions.
