Introduction

Signal Integrity Studio is an add-on to the LeCroy SPARQ application software. With SI Studio, users
can analyze the signal integrity characteristics of a channel, including its eye diagram and jitter. The
channel is described by its S-parameters, which can either be measured by an attached LeCroy
SPARQ Signal Integrity Network Analyzer, or output from a VNA or other S-parameter modeling
software. Signal Integrity Studio features the following:

 Seamless integration with LeCroy SPARQ S-parameter measurements
 Full signal integrity analysis of equalized receiver
 Fast eye diagramming
 Advanced jitter analysis, including Tj / Dj / Rj jitter breakdown
 Co-simulation of measured and/or modeled network characteristics
 De-embedding and emulation of channel and fixture responses
 Inclusion of pre-emphasis or de-emphasis to the simulated signal
 Emulation of CTLE, DFE and/or FFE equalizers
 Operates independently on the user's PC or as an option with the LeCroy SPARQ hardware.

Summary of Signal Integrity Studio
Capabilities

The Signal Integrity Studio capabilities of the SPARQ software
application are contained within three items found within the
Analysis menu:

 Simulator: Opens up the SPARQ Simulator Dialog for

configuring the simulated signal that is input to the
EyeDoctorII and/or Serial Data features

 Eye Doctor II: Opens up the Eye Doctor II Dialog for

configuring pre/de-emphasis, channel emulation/de­embedding, and equalization

 Serial Data: Opens up the SDAII Dialog for setting up the

application to measure eye diagrams and to perform jitter
analysis.

Detailed information about these capabilities is included within
the online help, and the Configuring Signal Integrity Studio: Step-
by-Step Instructions topic in this document includes information
on getting started with each feature. Note that the EyeDoctor II
and SDA2 items are identical to capabilities that are available on
certain LeCroy oscilloscopes

Operation without a LeCroy SPARQ

When purchasing Signal Integrity Studio as a standalone package or when using the software
without a SPARQ network analyzer the SI_STUDIO option is enabled by running the
SPARQ application with the supplied USB license key plugged in. Once the application is running, you
can confirm that the option is enabled in Verifying the Signal Integrity Studio Software Option (on
page 6).

Note: Without the license key, the SPARQ application will run, but the Serial Data, Eye Doctor II and
Simulator menu items will not be present in the Analysis menu.

SI Studio as a SPARQ Network Analyzer Option

When purchasing Signal Integrity Studio along with a SPARQ network analyzer, the option code
SI_STUDIO is added to your SPARQ at the factory. A USB license key is also provided to allow for
operation when your SPARQ is not connected to your PC. Note that when a SPARQ is connected, the
USB license key is not needed, since the software will obtain the software options from the SPARQ
hardware rather than the USB license key. You can confirm that the option is included on your
SPARQ in Verifying and/or Adding the Signal Integrity Studio Software Option (on page 6).
