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.
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.
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.

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.
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
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.
