Chestnut Ridge, NY, March 24, 2015 — Teledyne LeCroy today announced significant enhancements to the two highest performance oscilloscope product lines in the company’s portfolio. From the introduction of the 30 GHz WaveMaster 8 Zi in 2009 to the 100 GHz LabMaster 10 Zi available today, these award-winning oscilloscope platforms have advanced Teledyne LeCroy’s technology leadership by aggressively pushing real-time bandwidth and sample rate boundaries. The new LabMaster 10 Zi-A delivers improved
Chestnut Ridge, NY, March 24, 2015 — Teledyne LeCroy today announces PAM4 Signal Analysis software
, the industry’s first PAM4 analysis tool for real-time oscilloscopes. This new set of analysis tools makes essential eye, jitter and noise measurements on all three eye openings of a PAM4 signal, a requirement for engineers who are designing next-generation electrical and optical links that seek to double data transfer rates by leveraging PAM4 signaling.
PAM4 encodes two bits of information per symbol rather than one by using a 4-level signal. This doubling comes at a price of increased signal complexity as compared to 2-level NRZ signaling. The PAM4 eye diagram contains 3 eye openings rather than one, and includes 12 types of transitions rather than two. Engineers must understand how their transmitters, channels, and links affect PAM4 eye quality, and quantify the degree of eye closure due to timing jitter and noise as a function of bit error ratio (BER).
Traditional serial data analysis tools found in oscilloscopes are designed to work with NRZ signals, forcing new measurement tools and techniques to be created for analysis of 4-level signaling. The new PAM4 Signal Analysis software is specifically designed for 4-level signaling and makes eye, jitter and noise measurements on all three eye openings of the PAM4 signal. Total jitter and noise are decomposed into random and deterministic components to give a full accounting of the jitter and noise behavior. In addition to quantifying jitter, and noise and eye height/width, the software allows users to understand the root causes of jitter by displaying a rich set of visualizations including histograms, tracks, spectra, and bathtub curves.
The PAM4 package is the latest in Teledyne LeCroy's long history of innovation in jitter and timing measurements on sophisticated signals. Teledyne LeCroy was the first oscilloscope company to offer dedicated jitter analysis software and serial data analysis oscilloscopes, and is now in its third generation of SDA software with SDAIII-CompleteLinQ. This package is the only one in the industry that compares eye, jitter and noise measurements on up to 4 lanes, simultaneously. The PAM4 analysis package builds on this experience, and is dedicated to analyzing PAM4 signals.
Pricing and Availability
PAM4 Signal Analysis is available for $9,990 (US list price).
