Open TEM Cells

  • Test to  international  and  automotive standards (IEC 61967-2,  SAE J1113-25 J1752-3) 
  • Use in ordinary facilities. No Chamber required
  • Test upt 3GHz (depending on Model)

Open TEM Cells

These open TEM cells (tri-plate cells) are well suited for immunity testing  of  small  objects  according  to  international  and  automotive standards (IEC 61967-2,  SAE J1113-25 J1752-3)  or  for  biological experiments. The advantage of these TEM cells is that they are open. This  enables  an  easy  access  to  control  the  device  under  test. Applications are for instance the immunity testing of watches, phones or PCB's. In comparison with other closed TEM cells, the price is lower. The field rapidly decreases outside the open TEM cells (about 33 dB at 1 meter) which makes it possible to use an open TEM cell in ordinary facilities. Another interesting application is the calibration of field probes because the field inside the TEM cell is known with high precision. TEM cells are the most precise structures for field calibration.
