TEM Cell

When it comes to testing electronic products or components to EMC susceptibility standards, you don’t have to have a full scale test anechoic chamber at your disposal. The IFI CC Series of TEM Cell (RF shielded Boxes and RF Shielded Enclosures) can offer the necessary environment for performing pre-compliance and compliance testing in a package that is convenient, cost-effective and (in certain respects) technically superior to the larger anechoic chambers on the market today.

Originally conceived by Mike Crawford at the National Bureau of Standards and further developed by IFI, the CC series TEM Cell consist of a rectangular transmission line operating in the transverse electromagnetic mode (TEM). The cell is tapered at each end to a transition section that includes type N coaxial jacks for signal connection.

Size and precision design of the CC series allow for accurate maintenance and measurement of E-Field levels (within ± 1.0 dB nominal on most models) without antennas. The geometry of the cell combined with its well maintained impedance minimizes undesirable resonance effects. In addition, the typical VSWR is less than 1.25 to 1. To summarize, the ability to produce, maintain and measure E-fields is considerably easier within a CC Series TEM cell than within the larger anechoic chambers.

The compact size of the CC Series allows them to be easily moved around, essentially acting as a “bench-top shielded room”. And with IFI’s line of amplifiers and accessory products, your whole test area can take up a fraction of the space of a standard EMC test facility.

With the average CC series TEM cell costing two to four percent of an average anechoic chamber, manufacturers could afford a complete test setup, and test labs can afford multiple test setups. We provide thirty-five models ranging in size and frequency, the CC series offers you a choice to fit your specific application needs.

Field Level Calculation:

The field generated inside the chamber may be calculated from the expression: E=V/D, where V is the input voltage to the cell and D is thespectrum to top plate seperation ("spectrum height" in the above chart).
To ensure that the test object "sees" a uniform field. ots dimensions should not exceed one third of the volume between the spectrum and the walls of the TEM cell (i.e., the "maximum test object size" in the above chart).
