Common mode voltage test applied the cables attached the product

Immunity to power frequency magnetic fi elds is performed by setting up current fl ow in a loop around the product or preferably by placing the product within the confi nes of a Helmholtz coil.

Table 25.8 : Test equipment

In immunity testing, the confi guration and operating conditions of the equipment under test can be very important. These conditions are usually specifi ed in the EMC standard applicable to the product but in the absence of specifi c information the test engineer must attempt to adjust the conditions for maximum sensitivity to the applied disturbance.
