What are the test paths for the radio frequency (RF) part of the EMC test? |
![]() |
Conducted EMI test |
The power cable of the DUT is connected to the simulated power supply impedance network (LISN) and the radio noise level of the product to be tested is transmitted to the measurement receiver to obtain the noise level. |
Radiated EMI |
Under normal use, the radio of the DUT is received over the air to an antenna of 3M or 10M away, and then it is transmitted to the measurement receiver to obtain the noise level. |
Conducted EMS test |
The noise test mixed in the power cable and the control cable is used to test the interference of the DUT after coupling the noise and the power source, such as using an impulse test. |
Radiated EMS test |
Simulate the interference of the DUT exposed to electromagnetic waves, and transmit the required RF power by the antenna. The common test range is 80MHz~1GHz, and 1V/m ~ 10V/m with AM 80% modulation signal. |
