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.
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.

17.3 Test Setup and Test Procedure
The surge is to be applied to the EUT power supply terminals via the capacitive coupling network.
Decoupling networks are required in order to avoid possible adverse effects on equipment not under
test that may be powered by the same lines and to provide sufficient decoupling impedance to the surge
wave so that the specified wave may be developed on the lines under test.
The EUT was arranged and connected according to its functional requirements
The EUT was placed on a 0.8m high wooden table, standing on a ground reference plane 2.6m by 1.8m
in size, supplied by the coupling-decoupling network (Best EMC). arranged and connected to satisfy its
functional requirement and the power code between the EUT and the
coupling/decoupling network was less than 2 meters.
