Tektronix BSA12500ISI BSA12500ISI Datasheet

BERTScope™ Differential ISI Board

Precision ISI Test Accessory

Key features

The board has been designed with the following features:

Specially designed to provide a low cost, high accuracy method of
introducing controlled amounts of Inter-Symbol Interference (ISI) for
stress testing and general lab use

Matched Differential Lines of the following nine lengths:

2.42", 5", 6.75", 9", 12", 17," 24", 31", 40"

Matched 3 dB attenuators for easy amplitude adjustment in compliance
testing for standards such as Serial ATA

The BERTScope Differential ISI Board meets the needs of engineers
constructing stressed eye type receiver jitter tolerance test signals. It
provides a convenient variety of realistic test channels for designers
wanting to exercise semiconductor circuits with features such as de­emphasis.

Flexible and easy to use around the lab with many different pieces of
test equipment

Connector pairs aligned for easy cascade of lines for added length

Individually characterized s parameter data optionally available

Correctly exhibits skin effect losses
