LAB_WM778 - Using LeCroy’s EyeDoctor™II

As signal speeds and data rates have increased to 5 Gb/s and greater while progation mediums have remained unchanged, engineers have had to face new challenges with signal integrity measurements. Eye Doctor™ II is a complete set of tools that adds precision to signal integrity measurements by permitting de-embedding and emulation (emphasis, serial data channel, or receiver equalization).
