4. Evaluation Of Performance 
 
4.1 Performance Criteria 
 
      Criteria A 
The equipment shall continue to operate as intended during the test. 
No change of actual operating state is allowed as result of the application of the test. 
Multifunction equipment shall for each function meet the relevant requirements. 
Evaluation is carried out for audio and video functions. 
1) Evaluation of audio quality 
The criterion of compliance with the requirement is a wanted to unwanted audio signal ratio of  ≥40dB  
at a wanted audio signal level of 500mV, or at another audio signal level specified by the manufacturer. 
2) Evaluation of picture quality 
In the evaluation of picture interference the wanted test signal produces a standard picture and the 
unwanted signal produces a degradation of picture. The degradation may be in a number of forms,   
such as a superposed pattern, disturbance of synchronization, geometrical distortion, loss of picture   
contrast, of color. 
The criterion of compliance with the requirement is just perceptible degradation by observation of 
the picture. The screen shall be observed under normal viewing conditions (brightness 15 lx to 20 lx), 
at a viewing distance of six times the height of the screen. 
 
      Criteria B 
The device shall continue to operate as intended after the test. No loss of function is allowed after   
the test when the apparatus is used as intended, but failures which are recovered automatically   
but which cause temporary delay in processing, are permissible. No change of actual operating   
state for example change of channel or stored data and settings is allowed as a result of the application 
of the test. During the test, degradation of performance is allowed.   
 
4.2 Measurement Uncertainty 
 
   Measurement uncertainty is calibrated in accordance with: 
      ●EMCIT document 93/30 
      ●NAMAS Information Sheet NIS81, Ed.1 May 1994 
(The treatment of uncertainties in EMC measurement). 
      The measurement uncertainty is not considered when deciding PASS or FAIL against the limit lines. 
      This means that “shared risk” (according to NAMAS publication NIS81 4.2) is used as option   
      Criterion. The argument for using this method, is that it is commonly accepted that the EMC limits   
      have already taken common good laboratory practice. 
 
4.3 Final Decision 
       
      The equipment under test complies to all requirements of the applied test standards.

6. Electrostatic Discharges 
 
6.1 Test Procedure 
     
 
A ground reference plane was located on the floor, and connected to earth via a low impedance   
      connection. The return cable of the ESD generator was connected to the reference plane. In case of     
      a floor standing equipment, EUT was placed on the reference plane on 0.1 m of insulating support. 
      In case of table-top equipment, EUT was placed on a wooden table 0.8 m above the reference plane. 
   A horizontal coupling plane(HCP) of 1.6 m x 0.8 m was placed on the table, and connected to the reference     
plane via a cable with a 470 ㏀  resistor located in each end(0.5 mm insulating support between EUT   
and HCP). In both cases a vertical coupling plane (VCP) of 0.5 m x 0.5 m was located 0.1 m from the   
EUT’s sides. The VCP was connected to the reference plane in the same matter as the HCP. The   
test was done by applying contact and air discharges to the EUT itself, and contact discharges to the HCP   
and VCP. When applying the discharges to the HCP, the tip of the generator was located at the front edge   
of each HCP opposite the center point of the EUT, at 0.1 m distance. When applying the discharges to the   
VCP the tip of the generator was located at the middle edge of the VCP. The VCP was located 0.1 m from   
each side of the EUT. Contact discharges up to  ±  4 kV were applied to various points of the EUT at   
conductive surfaces, and to the HCP/VCP. Air discharges up to  ±  8 kV were applied to various points of   
the EUT at non-conductive surfaces. 
Ungrounded equipment, or ungrounded part(s) of equipment, cannot discharge itself similarly to class I 
mains-supplied equipment. If the charge is not removed before the next ESD pulse is applied, it is   
possible that the EUT or part(s) of the EUT be stressed up to twice the intended test voltage. Therefore, 
double-insulated equipment could be charged at an unrealistically high charge, by accumulating several 
ESD discharges on the capacitance of the class II insulation, and then discharge at the breakdown voltage 
of the insulation with a much higher energy. In the case of class II & III equipment, to avoid of unrealistically   
high charge, it is possible to ionize “using ionizer” before each discharge.
