LeCroy(R) Corporation introduces Eye Doctor, a digital oscilloscope (DSO)-based instrumentation and co-simulation system that specifically addresses the challenges of analyzing serial data created by the increase of systems’ symbol rates and adoption of receiver equalization. Designed for use with LeCroy’s SDA (serial data analyzer) instruments, Eye Doctor is a major enhancement that enables interoperability measurements to be made on equalized serial data systems.
Eye Doctor is the first system that combines the signal acquisition power of a DSO with sophisticated digital signal processing (DSP) for digital filter synthesis and simulation, thereby allowing engineers to capture and view real-world GHz signals, explore equalization schemes, compare and test waveforms, and model the signal at the output of simulated interconnects and transmission systems.
Eye Doctor provides the tools to undo or compensate for common forms of distortion, resulting in increased signal-to-noise, opened eyes, increased rise time, and reduced jitter. It also restores lost bandwidth and improves waveform fidelity. Eye Doctor achieves this improved analysis capability, in part, because it incorporates two unique elements – Virtual Probing(TM), which enhances the accuracy of measurements made on distorted waveforms, and equalized receiver emulation, which allows measurements to be made from a “receiver’s eye view.”
Virtual Probing simulates signals from any point within the system using a single measured waveform. Its Processing Web Editor is used to connect the equalizer and Virtual Probing elements in an intuitive signal flow diagram layout. Virtual Probing can be used to de-embed probe and fixture responses from measurements to improve the accuracy of signal integrity measurements.
The equalized receiver emulation includes FFE (Feed Forward Equalization) and DFE (Decision Feedback Equalization), as well as clock recovery and a variable decision threshold. It reveals the signal as seen within a real receiver at the detector, which has been previously unattainable via a probe. The equalized signal can be measured using the SDA’s powerful jitter and signal analysis software so that the bit error rate, total jitter, and eye opening can be measured, to provide engineers with a precise indication of the performance margin.
The Eye Doctor is now standard on all newly-shipped LeCroy SDA6000A, SDA6020, SDA9000, SDA11000, and SDA18000 models. It is also standard on the WaveExpert(R) series SDA100G. Current SDA users can install Eye Doctor on their existing SDA with a simple retrofit kit. The LeCroy SDA family of products, built on the world’s fastest real-time oscilloscope architecture, delivers outstanding real-time measurement solutions for signals with data rates up to 10 Gb/s. They combine the analysis capability of several different classes of equipment in one single-instrument solution.
Eye Doctor 1.0 is available 6 weeks ARO. It is available for immediate delivery as 0.9 Beta version. The SDA family has a price range of $34,500 – $128,000.
