16.3 Test Setup and Test Procedure 
 

16.3.1 Test setup 

 

 

The test was conducted in an anechoic chamber which is 7m in length, 5m in width and 3m in 

height   to  maintain a uniform field of sufficient dimensions with respect to the EUT, and also in 
order to  comply with various national and international laws prohibiting interference to radio 
communications. 

  

 

 

For the table top EUT, the equipment is placed in the test facility on a non-conducting table 

0.8m high. 
 

For the floor standing EUT, the equipment is placed in the test facility on a non-conducting 

support 0.1m high. 
 

The EUT was placed on the uniform calibrated plane which is 3V/m EM field. 

 
 

Unshielded parallel wire was used during the test. 

 

 

 

Wire is left exposed to the electromagnetic field for a distance of 1m form the EUT.

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 frequency range 80MHz 

to 1000MHz, both polarizations was checked. 
 

After calibration, the EUT is initially placed with one face coincident with the calibration 

plane. 
 

The frequency range is swept from 80MHz to 1000MHz, with the signal 80% amplitude 

modulated  

with 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. 

 

Both horizontal and vertical polarization was conducted.
