The demo boards of the DB 20 set are modules for demonstrating immunity and interference emission phenomena.
The boards are designed for demonstrations of various EMC measuring devices such as spectrum analyzers and near-field probes, as well as ESD and burst generators from all manufacturers. Interference emission measurements with an antenna are also possible.
The set includes four different demo boards. These can be used to clearly demonstrate electrical and magnetic coupling mechanisms of immunity and emission on one board each.
The operating instructions for the DB 20 set present various experiments and measurement setups using the development systems Immunity E1 and Emission ESA1, the burst transformer PT4 and various near-field probes from Langer EMV-Technik GmbH.
These measurement setups are suggestions. The experiments and measurement setups can also be simulated with other measuring devices and modified in many ways.
