7. Immunity to RF voltages (in common mode) (S2b)
7.1 Test criteria and test procedure
Operating environment;
Temperature
20 ℃
Relative Humidity
40 %
During the test of immunity to RF voltages (in common mode) the EUT was placed 0.1 M above
a metallic ground plane of dimensions 2 x 1 M.
The criterion concerning acceptable sound interference is a wanted to unwanted audio signal
ratio of ≥40 dB at a wanted signal level of 50 mW.
The requirements for receivers, multifunction equipment and video tape equipment concerning
the immunity to RF voltages in common mode are restricted to the antenna terminals and
to the frequency range from 26 MHz to 30 MHz.
The cables linking the coupling units to the EUT was short.
A band pass filter was connected to the test system and was used for the EUT AF outputs.
All unused inputs/outputs of the coupling units was terminated with the proper resistance.
The power cable of the EUT was uniformity bundled together and as short as possible.
The measurements were performed with test software TS9980 Ver.2.9.
7.2 Measurement uncertainty
Immunity to conducted currents : +/- 2dB
7.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.

The EUT was placed on a non-metallic support,0.1m above the lower conductor in the center
of the stripline.
The wanted signal was fed to all input terminals respectively. The unwanted signal is fed to
a matching network of the strip line.
The criterion concerning acceptable sound interference is a wanted to unwanted audio signal
ratio of ≥40 dB at a wanted signal level of 50 mW.
The audio output power was measured with a 0.5 - 3 kHz band-pass filter.
The ground connection of the mains filter (M) was directly connected to the jacky.
The audio analyzer was applied without a weighting filter.
The measurements were performed with test software TS9980 Ver.2.9.
8.2 Measurement uncertainty
Radiated fields : +/- 2dB
8.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.

9.1 Test criteria and test procedure
Operating environment;
Temperature
20 ℃
Relative Humidity
40 %
The equipment under test was placed on a non-metallic table of height 0.8 M.
At the side of the antenna input terminal of the equipment under test, a non-metallic table
of length 4 M was placed at the same height to provide for movement of the measuring
device, an absorbing clamp.
An RF signal generator is placed on a third table.
The equipment under test is connected to the generator, but not connected to the mains supply.
The signal from the generator is at the test frequency and unmodulated.
9.2 Measurement uncertainty
Radiated fields : +/- 2dB
9.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.

10. Electrostatic Discharges (EN 61000-4-2)
10.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
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 10cm of insulating support
In case of table-top equipment, EUT was placed on a wooden table 0.8m above the reference planed On the
floor. A horizontal coupling plane(HCP) of 1.6*0.8m was placed on the table, and connected to the reference
plane via a cable with a 470 ㏀ resistor located in each end(0.5mm insulating support between EUT and HCP).
In both cases a vertical coupling plane (VCP) of 0.5*0.5m was located 10cm 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 each side of the
EUT, at 10cm 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 10cm from each side of the EUT.
Contact discharges of ±4kV were applied to various points of the EUT at conductive surfaces, and to the
HCP/VCP. Air discharges of ±8kV were applied to various points of the EUT at non-conductive surfaces.
