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).Using LeCroy’s EyeDoctorII APPLICATION BRIEF LAB-WM778 March 11, 2009 Figure 1 shows a summary view of Eye Doctor II’s capabilities. The eye diagram of the input signal in the upper left quadrant shows the effects of transmitter de-emphasis plus channel and fixture losses. In the upper right eye Summary 3.5 dB of de-emphasis has been removed. The eye diagram with the fixture effects removed and a serial data channel emulation, as described by their As signal speeds and data ……
