This test method is designed to irradiate electromagnetic fields to ESA (in-vehicle electronic equipment) and harnesses, and can generate a high electromagnetic field environment with dramatically lower power requirements than the antenna irradiation method.
This test method evaluates the operation of in-vehicle electronic equipment by generating an electromagnetic field using a strip line with a characteristic impedance of 50 Ω or 90 Ω.
The system covers a wide range from 10k to 1 GHz, but requires a shielded room or an anechoic chamber for reasons of field leakage to the outside (because unlike TEM cells, it is not shielded) and the stability of the generated field mode.
- High electric field can be generated with a small power amplifier.
- Intelligent dedicated design software.
- Uses low harmonic power amplifier (-20dBc) to meet standard test requirements.
- Supports AM, FM, pulse modulation as well as digital modulation.
- Various hardware/software protection functions as standard equipment to enhance safety.
- Superimpose function is available as an option to record the test condition with the camera image.
