Sometimes complex parameters from individual measurements have to be mapped mathematically, such as various ACR values, which in principle express the signal-to-noise ratio. A "service-neutral" statement about the performance class of the system then results from the overall consideration of all parameters, which in turn allows conclusions to be drawn about the possible applications and protocols to be transmitted.
The device confirms this and records it in a standardized form. The second important piece of information in the term "cabling rectifier" is "cabling". This means that such measuring devices do not evaluate the components individually, but evaluate the data path as a whole, usually consisting of a data socket, distribution panel and data cable in between.
This fact is often not taken into account in practice, because many installers still believe that the installation cable, for example, is the only determining element.The classic at this point: The installer who terminates a Category 7 data cable with "cheap" Category 5 sockets and panels and complains terribly that his measuring device "already" "fails" with Category 6 measurement indicates, although it measures far below the suitability of the data cable.
