Rev081219
1) Set up the equipment as described in the applicable standard or approved
test plan. An example setup diagram is given in Figure 19. Refer to RTCA DO-
160 or the applicable test plan to determine the EUT cables to be tested.
2) Turn on all EUT equipment and test equipment and allow sufficient time for
stabilization. Set the frequency of the signal generator and measurement
equipment to 10 kHz with 1 kHz square wave modulation, with at least 90%
depth. Verify that the modulation is present on the drive signal and that
modulation frequency, waveform and depth are correct.
3) Adjust and control the forward power to achieve the induced current on the
cable bundle for the selected category level (see section 6.2). When
necessary, limit the forward power to not more than
6 dB above the calibration
value recorded during Step 4 of the Test Level Calibration Procedure described
in Section 6.3. Record the induced current and applied forward power in the
test report.
4) Evaluate EUT operation and determine compliance with applicable
equipment performance standards.
5) Set the frequency of the signal generator and measurement equipment to the
next test frequency.
6) Repeat Steps 3-5 until the test has been performed at all test frequencies.
7) Repeat Steps 2-6 until all required EUT cables have been tested.
