5.7.2 TEST PROCEDURE
1) Set up the EUT, CDN as shown on Section 5.7.3
2) Let the EUT work in test mode and measure it.
3) The EUT are placed on an insulating support 0.1m high above a ground reference plane. CDN
2) Let the EUT work in test mode and measure it.
3) The EUT are placed on an insulating support 0.1m high above a ground reference plane. CDN
(coupling and decoupling device) is placed on the ground plane about 0.3m from EUT. Cables
between CDN and EUT are as short as possible, and their height above the ground reference
plane shall be between 30 and 50 mm (where possible).
between CDN and EUT are as short as possible, and their height above the ground reference
plane shall be between 30 and 50 mm (where possible).
4) The disturbance signal described below is injected to EUT through CDN.
5) The EUT operates within its operational mode(s) under intended climatic conditions after
5) The EUT operates within its operational mode(s) under intended climatic conditions after
power on.
6) The frequency range is swept from 150 kHz to 80MHz using 3V signal level, and with the
disturbance signal 80% amplitude modulated with a 1 kHz sine wave.
7) The rate of sweep shall not exceed 1.5*10-3decades/s. Where the frequency is swept
incrementally, the step size shall not exceed 1% of the start and thereafter 1% of the preceding
frequency value.
frequency value.
8) Recording the EUT operating situation during compliance testing and decide the EUT immunity
criterion.
