EMC Test Report
Reference No.: NK08E 683.EMS
11. Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test (EN61000-4-3)
11.1 Test criteria and test procedure
Operating environment;
Temperature:
23 ℃
Relative Humidity:
40 %
The tests were performed at 3m 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 0°, 90°, 180°, 270°
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
