TEM Cells

A TEM Cell (Transverse Electromagnetic Cell) is a specialised, “shielded-box” transmission line used to perform radiated emissions and immunity testing on a small scale. It acts as a compact, cost-effective alternative to a full-sized anechoic chamber, allowing engineers to create or measure electromagnetic fields in a controlled, enclosed environment.

Why Choose a TEM Cell?

Consistent Field Uniformity: Unlike testing in an open room where reflections and ambient noise interfere, a TEM cell creates a very stable and uniform electromagnetic field between its internal "septum" and the outer walls.
Ambient Noise Rejection: The shielded enclosure blocks out external radio signals (Wi-Fi, Cellular, Radio), allowing you to measure the tiny emissions from your device with extreme clarity.
Space and Cost Efficiency: They provide a professional testing environment that fits on a laboratory workbench, costing a fraction of the price of a walk-in shielded room or EMC chamber.
Bidirectional Capability: A single TEM cell can be used for both Emissions (measuring what comes out of your product) and Immunity (blasting your product with RF to see if it fails).

Core Applications

Pre-compliance Radiated Emissions: Quickly checking if a PCB or small electronic assembly exceeds legal limits (like CISPR 22/32) before sending it for final, expensive certification.
RF Immunity Testing: Using a signal generator and amplifier to subject a small device to high-strength fields (e.g., 10V/m or more) to test for software crashes or sensor interference.
Sensor Calibration: Providing a known, precise electromagnetic field strength to calibrate RF probes, field meters, or wireless sensors.
Shielding Effectiveness Testing: Placing a component inside the cell to measure how much RF energy it leaks, helping engineers optimize gaskets, enclosures, and cable shielding.
