7. Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test
7.1 Test Procedure
The tests were performed at 3 m distance in an anechoic chamber.
For floor-standing equipment, the EUT was mounted non-conducting support 0.1 m above the
supporting plane. For tabletop equipment, the EUT was located on a wooden table 0.8 m above the floor.
The EUT was exposed to the field from different angles, normally 0º, 90º, 180º, 270º and at both horizontal
and vertical polarization(antenna height 1.75 m)
A signal level of 3 V / m, duty cycle 1 / 8 pulse modulated with a 217 Hz sine wave was applied in the
frequency range 900 MHz. During the test the 1 kHz unwanted noise level comes from the speaker was
detected using microphone and selected level meter

8. Fast Transients/Burst
8.1 Test Procedure
The minimum area of the ground reference plane is 1 m x 1 m, and connected to earth via a low
impedance connection.
The EFT/Burst generator was located on the ground reference plane.
The EUT was located 0.1 m above the ground reference plane and the length of power line between the
EFT/Burst generator and the EUT is 0.5 m.
The minimum distance between the EUT and all other conductive structures, except the ground
reference plane is more than 0.5 m.
The test voltage was applied simultaneously between each of the power supply conductors and the
protective earth at the power supply.
