TPL 3000 TRI-PLATE LINE 10 kHz TO 1 GHz EMC tests for vehicle components immunity to RF fields The Tri-Plate test method is specified in the surface vehicle standard SAE J1113-25 ”Electromagnetic Compatibility Measurement Procedure for Vehicle Components-Immunity to Radiated Electromagnetic Fields, 10 kHz to 1 GHz” and applicable for testing products such as air-bag control modules, engine and transmission control modules and other subsystems and their associated cables. The EUT height should be less than 1 / 3 of the distance between septum and outer plates. The Tri-Plate Line (TPL) works as an open TEM cell. It is a broadband parallel-plate construction with grounded top and bottom outer plates and an isolated center-plate. When RF signals are input at one end, the TPL will generate an electro-magnetic field between the plates. The opposite end is terminated with a 50 Ω load. A typical test configuration consists of signal generator, power amplifiers, power meters, TPL, 50 Ω load and (absorber lined) shielded room. The TPL 3000 is designed as specified in the SAE J1113-25. The TPL 3000 is shipped in a transportable form with complete assembly instructions for customer on-site installation.
