Since the SGZ 21 has to be connected directly to the printed circuit boards, the housing must be removed
as far as possible (Figure 21).
Figure 21: Device without housing; the printed circuit boards are connected and functional.
The areas between the printed circuit boards are hard to reach in the device under test. The printed circuit
boards may therefore have to be removed from the device and arranged with their original connections
alongside each other. The printed circuit boards can be unfolded directly and are then easily accessible if
they are flexibly connected in the device under test. If, however, they are firmly connected by pin shrouded
headers, for example, they can only be unfolded with additional adapters (Figure 22).

boards.
The printed circuit boards of the device under test are now fully accessible and disturbance current can be
selectively coupled to them via a two-pole connection.
