Differential ISI Board
 The BERTScope ISI test fixture has been
specifically 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.
Flexible and easy to use with the BERTScope or your existing test
equipment, it is easy to move between test setups for stress testing and general
lab use.
- Matched differential lines in nine lengths: 2.42",
5", 6.75", 9", 12", 17", 24", 31", and 40"
- Matched 3 dB attenuators for easy amplitude adjustment
in compliance testing for standards such as Serial ATA
- Connector pairs aligned for easy cascade of lines to
add length
