Tekbox open TEM cell TBTC1
Details
The Tekbox TBTC1 is an open TEM cell, developed for EMC pre-compliance testing of small DUTs. The TBTC1 is also used for radiated emissions tests and immunity tests. The open TEM cells offer an inexpensive alternative to testing these DUTs in comparison with the standard tests in anechoic chambers. The TEM cell can be connected to a spectrum analyser or an RF receiver. The TBTC1 comes with a 50/25W RF termination stop and a DC block to protect the connected device.
Thanks to the open design, the DUT can easily be placed in the TEM cell. It must be placed between the lower wall and the septum, the conductive strip in the middle section. A unique feature of the Tekbox TEM cells is that they can suppress higher orders of waves and resonances. In addition, these TEM cells have a better frequency response than the standard TEM cells.
Model overview
The models within the Tekbox open TEM cell series differ from each other mainly in measuring volume and frequency range.
