6 Electromagnetic compatibility (EMC) tests

AN2208

28/51

6.6.1

Power supply tests

Figure 25 illustrates the power supply test setup. The test voltage is applied by coupling

decoupling networks CDN. The maximum voltage is 10 VRMS. The maximum distance between

EUT and CDN is 0.3 meters. All Auxiliary Units (AU) such as power supplies switching devices

must be placed on the wood isolation.

6.6.2

Input port tests

Figure 26 illustrates the input port test setup. The test voltage from the signal generator to the

EUT is applied by the current clamp. This device establishes inductive coupling to the cable

connected to the EUT. The maximum distance between the EUT and the CC is 0.3 meters. The

test is performed while the HSD input port is switched On/Off at 1Hz.

6.6.3

Output port tests

Figure 27 illustrates the output port test setup. The power supply must be protected to

disturbance signal by a decoupling network. The current clamp is used as the coupling device
