All remote controls developed by Tyro are in compliance with the EMC directive. EMC stands for Electromagnetic Compatibility and the purpose is to prevent interference from and to other apparatus. In addition, it is also very important that the apparatus is immune to interference from external sources. The EMC standard is applicable in all countries that are members of the European Community and may be tested only by approved bodies.
Our latest radio remote control “Pollux” is also subject to EMC tests. One of the tests was done in an anechoic space; also called “anechoic chamber”. The closed area includes sound absorbent material in the form of wedges that not only absorb sound, but also ensure that electromagnetic radiation can not be reflected.
The EMC test
Our remote control was placed on a table with the receiver next to it. The standards for these tests are exceptionally precise, so that the same test can be reproduced at any moment. The remote control, must be 10 cm from the receiver, also the cables must hang at a given height above the floor. No one is allowed in the anechoic chamber during this test, but it can be followed live by means of a camera.
Virtually fully automatic
The impressive part of this EMC test is that almost everything is automated. The operator, using his computer, enters which frequencies the test is subject to and then, as it were, waits for the results. Not only the antenna moves automatically from top to bottom; also the table rotates mechanically, so that the product can be tested from different angles with different frequencies.
In addition to the test in the anechoic chamber the remote controls are also subject to static discharge (ESD) and heavy energy-rich pulses (Surge). There are many other tests that can be carried out to meet the various norms, so that the remote controls made by Tyro can be used safely in public.
