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
