a) The testing was performed in a fully anechoic chamber. The transmit antenna was located at a 

distance of 3 meters from the EUT. 

b) The frequency range is swept from 80 MHz to 1000 MHz; 1.4 GHz ~2.7GHz, with the signal 

80% amplitude modulated with a 1 kHz sine-wave. The rate of sweep did not exceed 1.5 x 10 

-3 

decade/s, where the frequency range is swept incrementally; the step size was 1% of preceding 
frequency value. 

c) The dwell time at each frequency shall be not less than the time necessary for the EUT to be able 

to respond. 

e) The test was performed with the EUT exposed to both vertically and horizontally polarized fields 

on each of the four sides.
