The 61000-4-20 is the standard for the Tem cells
Emission
The Tem cell is a different and cost efficient method, compared to the OATS, to measure the emission patron of the EUT. This method does have a down side, calculation is needed to correlate the measurements done in the Tem cell to the OATS
For the emission there are 2 ways of calculation:
- multi pole model
- three voltage measurements
Multi pole model
The multi pole model is currently not supported by RadiMation®
Voltage measurements: 3-Positions
Also known as the "To Radiated Power method". In this method the EUT is placed in 3 axis (x,y,z).
![{\displaystyle S[V]={\sqrt {V_{x}^{2}+V_{y}^{2}+V_{z}^{2}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/b10cfd38ece759e601479944be52972d11c0f512)
, and are the measurements done in Volt on the same frequency but in different directions.
