Plug and Play!

To avoid reduced integrity of the data transfer due to interference and to pass EMC tests, components matched to the data lines are necessary.

For simplified implementation, the adapter stick was designed, which contains a complete filter circuit for the selected application. The filter stick is plugged into the corresponding interface for test purposes. If the test is passed with the filter stick plugged in, the filter circuit can be integrated into the system.

1. Plug in filter stick
2. Check filter effect
3. Implement the circuit in the system
