Upgrading an EMC chamber with new absorbers on old tiles
Can you upgrade an EMC chamber and keep the old, glued ferrite tiles? “It’s possible”, says Uliana Trucchi, one of our technical consultants. “Say you want to replace your old absorbers because you need to meet performances over 1GHz, and you wish to keep the ferrite tiles because they are glued to the chamber’s walls and ceiling. That is exactly what the people from Nemko in Germany asked us for the chamber upgrade in the photo.”

When is it time to acquire a full anechoic chamber (FAC) instead of a semi-anechoic chamber (SAC)? After delivering 21 chambers and upgrades for the leading French test house, Groupe Emitech, we approached their Group Director of Purchasing and former Deputy Technical Director, Julien Joly, with this question.
Julien Joly: “A few weeks ago, Comtest completed two new FAC3 chambers for our test house in the north of the city of Angers. We have a growing demand for tabletop product testing, and a FAC chamber makes testing much faster. Moreover, we have an increasing need to perform ETSI measurements; for those, the FAC is ideal. In the new situation, we do not always have to change the setup (floor absorbers), like moving from chamber to chamber and changing setup equipment. Working faster makes our professional lives easier and the work more efficient: we can do more tests in a day in the new setup.
We serve more than 850 companies in France, with our 57 chambers in eight locations. Almost half of them were designed and built by Comtest over the past nine years, so we work together very well.”
Uliana Trucchi, our senior technical consultant, has been our contact for Emitech since the beginning. She recalls an anecdote about the smooth way of working with Emitech. Uliana: “The level of knowledge is very high at Emitech, so the projects are well-prepared and specified by them before they get to us. After a few years, we started calling this smooth way of cooperating ‘working à la Emitech’. We try to make their lives easier, and they surely make working with them quite smooth for me.”
