Preface
IConnect® and MeasureXtractor™ is TDR (time domain reflectometry) software that provides high-speed interconnect
characterization. It is an integrated tool for measurement, compliance testing, modeling and validation for interconnects in
printed and flexible circuit boards, packages, ATE sockets, connectors, cables, and cable assemblies. IConnect provides
accurate measurements and equivalent circuit models that predict reflections, ringing, and crosstalk in interconnects.
This software supports signal acquisition from the following instruments:
Tektronix: DSA8300 (recommended), DSA8200, CSA8000, CSA8000B, CSA8200, TDS8000, TDS8000B, and TDS8200

If you plan to run IConnect on a PC and acquire waveforms from an oscilloscope connected to a LAN, or run the S-parameter
Wizard function (on the oscilloscope or remotely from a PC), you must install TekVISA software on your PC.
NOTE. TekVISA is already installed on Tektronix DSA8300 oscilloscopes. Legacy Tektronix sampling oscilloscopes
(DSA8200 series and earlier) will need to have the specified version of TekVISA installed to correctly operate with this
release of IConnect.
1. Check which version of TekVISA is installed on your oscilloscope and PC (open the TekVISA tool and click Help
> About). If the version is earlier than 3.3.4.6, go to the Tektronix Web site (www.tektronix.com/software), search
for tekvisa, and download version 3.3.4.6.
2. Follow the installation instructions provided with the TekVISA download file.

ng IConnect on a Tektronix Oscilloscope
You can install and run IConnect on a supported Tektronix oscilloscope. Running IConnect on an oscilloscope makes it
unnecessary to use a separate PC with a GPIB card, keeping your benchtop area less cluttered.
To most effectively run IConnect on legacy Tektronix sampling oscilloscopes (models earlier than the DSA8300), connect
an external 1024 x 768 resolution monitor to the oscilloscope. The external monitor lets you view all of the IConnect user
interface, while the instrument display shows the application software. See your oscilloscope documentation for help on
setting up dual monitor support.
NOTE. You do not need theTekVISA software to run IConnect on a separate PC that is connected to an oscilloscope directly
through a GPIB interface card. However, you do need TekVISA to remotely operate IConnect over a local area network
or to run the S-parameter Wizard.
