This TEM cell is great for radiated emissions and immunity pre-compliance testing and troubleshooting on your desktop.
It won’t give you absolute measurements as you’d find at an open area test site (OATS) or in a semi-anechoic chamber (SAC), but it’s great for several things:
- Fast radiated emissions troubleshooting. Make relative measurements to verify the improvements of PCB and/or component changes.
- Compare the emissions performance of parts from several vendors (again, relative measurements).
- Feed in a signal from a signal generator (via a small RF amplifier) to generate significant field strengths. This is great for radiated immunity pre-compliance testing and troubleshooting.
- Compare emissions and immunity performance of different PCB revisions
Chances are that this device can save you many expensive days in a 3rd party test lab.
All TEM cells are supplied together with a 50Ω/25W RF termination, a DC block to protect the spectrum analyzer or RF receiver input and an N-Male to N-Male coaxial cable.
The TBTC3 is the largest TEM offered from the TekBox range.
