“I’ve known the people at TTMS for years. An open and honest relationship has developed in which we can say everything to each other, resulting in a short but powerful communication. This increases efficiency, both for me and for TTMS. Ever since I developed monitors at Philips, we have been using their video protocol test equipment for our latest protocols. By listening carefully, TTMS and their manufacturers respond to our needs. The mutual benefit is that we get good support and they make better testers. In my current developments and tests on Signify connected LED lighting systems, we use various power supplies, electronic loads and analyzers. If TTMS has something new that is of interest to me, they know that I am positively critical of it. I’m looking for reliable equipment that is easy to use and TTMS continues to keep an eye out for new possibilities. For many years now, we have had a pleasant cooperation that works both ways. They know the market well and know how to find the right manufacturers for the right equipment.”
