16.3.2 Test procedure 
 
 
The EUT was arranged and connected according to its functional requirements 
 
Before testing, the intensity of the established field strength have been checked by placing the 
field sensor at a calibration grid point, and with the field generating antenna and cables in the same 
positions as used for the calibration, the forward power needed to give the calibrated field strength was 
measured. 
 
Spot checks was made at a number of calibration grid points over the frequen
MHz 
to 1000MHz, both polarizations was checked. 
 
After calibration, the EUT is initially placed with one face coincident wi
libration 
plane. 
 
The 
 range is swept from 80MHz to 1000MHz, with the signal 80% amplitude 
modulated  
 a 1 kHz sinewave, pausing to adjust the r.f. signal level.  
 
 
The dwell time at each frequency was 3s so as that the EUT to be exercised and be able to 
respond. 
 
The step size was 1% of the fundamental with linear interpolation between calibrated points. 
 
Test was performed with the generating antenna facing each of the four sides of the EUT.
