TBTC1 - 50mm - TEM Cell for EMC Pre-Compliance Testing
Overview
A TEM cell is a stripline device for radiated emissions and immunity testing of electronic devices. It is not a replacement, but due to its size and cost it is a convenient alternative to measurements in an anechoic chamber.
A TEM cell consists of a septum, the conductive strip in the centre section and walls which are connected to ground. The geometry is designed to present a 50Ω stripline. The device under test (DUT) is placed in between the bottom wall and the septum.
The TBTC1 is a so called “open TEM cell”, which got no side walls for convenient placement of the DUT. It may pick up RF background noise, which however can be taken into account by doing a measurement of the cell output signal before powering on the DUT.
The TBTC1 is designed for frequencies up to 700MHz, however it can also be used at frequencies beyond 1GHz.
The device is supplied together with a 50Ω/25W RF termination and a DC block to protect the spectrum analyzer or RF receiver input.
Radiated emission tests: the septum of the TEM cell picks up radiated noise from the DUT, similar to a broadband antenna, and presents it to the analyzer input.
Radiated immunity tests: the TEM cell will be connected to the output of a swept signal generator + RF amplifier and the septum radiates into the DUT.
