11. Test Procedure (CS)
a. The EUT shall be operated within its intended climatic conditions. The temperature and relative
humidity should be recorded.
b. This test method test can be performed without using a sell shielded enclosure. This is because
the disturbance levels applied and the geometry of the setups are not likely to radiated a high
amount of energy, especially at the lower frequencies. If under certain circumstances the radiated
energy is too high, a shielded enclosure has to be used.
c. The test shall be performed with the test generator connected to each of the coupling and
decoupling devices in turn while the other non-excited RF-input ports of the coupling devices are
terminated by a 50 ohm load resistor.
d. The frequency range is swept from 150 KHz to 230 MHz, using the signal levels established during
the setting process, and with the disturbance signal 80% amplitude modulated with a 1KHz
sinewave, pausing to adjust the RF-signal level or to switch coupling devices as necessary. The
rate of sweep shall no exceed 1.5 x 10
-3
decades/s. Where the frequency is swept incrementally,
the step size shall no exceed 1% of the start and thereafter 1% of the preceding frequency value.
e. The dwell time at each frequency shall not be less than the time necessary for the EUT to be
exercised, and able to respond. Sensitive frequencies e.g. clock frequency(ies) and harmonics or
frequencies of dominant interest shall be analyzed separately.
f.
An alternative test procedure may be adopted, wherein the frequency range is swept incrementally,
with a step size not exceeding 4% of the start ad thereafter 4% of the preceding frequency value.
The test level should be at least twice the value of the specified test level.
g. In cases of dispute, the test procedure using a step size not exceeding 1% of the start and
thereafter 1% of preceding frequency value shall take precedence.
h. Attempts should be made to fully exercise the EUT during testing, and to fully interrogate all
exercise modes selected for susceptibility.
i.
The use of special exercising programs is recommended.
j.
Testing shall be performed according to a Test Plan, which shall be included in the test report.
k. It may be necessary to carry out some investigatory testing in order to establish some aspects of
the test plan.
