SDAIII-CompleteLinQ Overview
The SDAIII-CompleteLinQ Serial Data Analysis package introduced with firmware version 6.9.0.x provides
comprehensive measurement capabilities for evaluating high-speed serial data signals.
SDAIII-CompleteLinQ builds on the power of SDAII, extending the analysis to up-to-4 lanes simul-
taneously, and providing a "reference" analysis lane for comparison purposes. SDAIII-CompleteLinQ is
the single-lane version. Both packages are a signal integrity analysis framework, integrating capabilities
from the EyeDoctor II, VirtualProbe and Crosstalk packages. In this manual, SDAIII-CompleteLinQ will
often be used to refer to the underlying analysis "engine"
Like its predecessor SDAII, SDAIII-CompleteLinQ operates by rapidly processing a long signal acquisition.
For best results, acquisitions should be long enough to include at least 100,000 UI of the signal under test
(500,000 UI or more is optimal). By using long acquisitions, users can have the best statistics for accurate
measurements and be able to measure low-frequency periodic jitter components.
The calculation methodology in SDAIII-CompleteLinQ is the same as SDAII, with the addition of the Dual-
Dirac "Rj Direct" jitter calculation method. All jitter measurements, eye diagrams and analysis views are
based on comparisons of the arrival times of the signals edges to that of the underlying clock, which is
determined either via a software clock recovery algorithm or by measurement of a clock signal. Nothing
is measured relative to the trigger; as a result, measurements are not affected by trigger jitter.
SDAIII-CompleteLinQ can be purchased as part of the standard installation on new instruments or as an
upgrade to existing instruments. See
