Most new serial I/O methods use
equalization techniques at the
receiver to help boost speed and extend the range of the technology.
Now there's a T&M system you can use
to design, build, and test such serial I/O
methods. LeCroy's Eye Doctor works with
the company's SDA series of digital sampling oscilloscopes (DSO).
This set of software tools combines
the signal acquisition power of a DSO
with digital signal processing (DSP) for
digital filter synthesis and simulation.
Users then can capture and view real-world gigahertz signals, explore equalization schemes, compare and test waveforms, and model the signal at the
output of the simulated interconnects
and transmissions systems.
Eye Doctor provides the tools to undo
or compensate for common forms of distortion resulting in increased signal-to-noise ratio, opened eyes, increased rise time, and reduced jitter. It also restores
lost bandwidth and improves waveform
fidelity. Its Virtual Probing enhances the
accuracy of measurements made on distorted waveforms, while its equalized
receiver emulation lets users make measurements from a "receiver's eye view."
Virtual probing simulates signals from
any point within the system using a single
measured waveform (). The
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 deembed probe and fixture responses from
measurement to improve the accuracy of
signal integrity measurements.
