On site measurements for Smit Mobile Equipment

The measurements of the effectiveness of the shielding (damping- or shielding-measurement) are being executed in shielded area’s in which the equipment is in, a so called ‘Cage of faraday. This room is being used to keep the electromagnetic fields outside, or in this case, inside the room.

Besides rooms like Smit builds this one for MRI-scan applications, such cages are also being used for measure rooms, computer rooms and other medical rooms.

The extent to which such spaces shield electromagnetic-fields, is being displayed by the ratio of the field inside and outside the room to a specific frequency band or at the given frequency points.

How is damping measured?

First of all, a reference measurement will be executed. This will measure the reference between de sending and receiving side outside of the shielded room.

After that, the receiving antenna including measurement equipment will be placed inside the shielded room and the sending antenna will stay outside of the room. The damping measurement will be repeated with conserving distance between the antenna’s where now a extra cage wall will be placed between the antenna’s. When all measurements are carried out, then on the base of calculations, the damping will be reported.
