1 SCOPE OF WORK A new version of the 24 VDC power supply unit (NERA part no. 104259), which is an integrated module in the NERA F77 Main Communications Unit has been EMC and climatic tested in order to verify compliance with requirements stated in the EU Council Directive 89/336/EEC of 3 May 1989 relating to Electromagnetic Compatibility for ship bridge area application. The testing has been carried out according to relevant parts of the following standard:

• IEC 60945 (2002, Fourth edition): Maritime navigation and radio communication equipment and systems - General requirements - Methods of testing and required test results

Based on evaluation carried out by the manufacturer, only properties that are considered to may have been affected by changes of the new power supply version have been tested. For each test, reference is made to the relevant section or paragraph in the standard. Only one specimen of the NERA F77 power supply unit has been tested. The test results thus apply solely for this specimen.

2 TEST LABORATORY The tests were carried out in the Environmental Test Laboratory at Det Norske Veritas, Høvik, Norway. Laboratory accreditation: NORSK AKKREDITERING, No. TEST 034 P6 – Electromagnetic Compatibility P17 – Environmental Testing P20 – Safety Testing According to NS-EN ISO/IEC 17025. Valid through 22.04.2008. Ambient conditions in the laboratory:

Parameter Required (IEC 60068-1) Actual Temperature 15 – 35 °C 21.1 – 23.5 °C Humidity 25 – 75 % RH (30-60 for ESD) 25 – 35 % RH (32 during ESD) Barometric pressure 860 – 1060 mbar 992 – 1023 mbar

3 TEST PERIOD The tests were carried out during the time period 18-10 to 08-11-2004.

4 ATTENDING REPRESENTATIVES The following client representative was attending the set-up of the system for testing:

• Bjarne Arthurson

5 EQUIPMENT UNDER TEST

5.1 Equipment submitted for tests A test system assembly comprising the NERA F77 power supply (NERA part no. 104259), which is defined as the test specimen was submitted for test. The power supply is an integrated part of the NERA F77 Main Communications Unit. The NERA F77 power supply will from now on be referred to as EUT (Equipment Under Test).

5.2 Test configuration The following Auxiliary equipment (AE) was used in order to operate and function test the system:

• Antenna system, NERA no: 100788 with a dummy load in place of the antenna • Laptop PC, Toshiba Satellite Pro, 440CDT running the “VtLiteMarine” test program • DC power source The following input/output power and signal ports were identified as relevant for EMC testing: All input and output ports of all units that are conducting power or signals were subject to conducted immunity testing.

Test set-up:

Test set-up for operation and monitoring of the EUT. Coupling networks and cabling modifications were applied as required to perform the tests according to the relevant standards.

5.3 Modes of operation The testing was carried out with the EUT • powered by 24 VDC from external source • running a test program that was set to operate the system at maximum RF power output level

5.4 Modifications during testing No modifications of the EUT were necessary to pass the tests.

6 EVALUATION OF PERFORMANCE DURING THE TESTS

6.1 Function testing and performance monitoring Correct function was verified during the tests by • observing the antenna visually • monitoring the RF power output as a function of the current drain from the external power

source and by monitoring the presence of the carrier frequency by means of a pick-up loop antenna and a spectrum analyser

• checking the ability to start up at test conditions

6.2 Criteria of acceptance In order to pass each test, the EUT shall meet the following criteria:

• Perform in compliance with the test specifications and referenced standards • No unintentionally movement of the antenna shall occur • RF power output and carrier frequency shall remain unaffected by the test conditions • Not show signs of other malfunctions For EMC emission tests, the criteria of acceptance are described in the relevant Chapters. For the EMC immunity tests, the results are evaluated against performance criteria relating to the operating condition and functional specifications of the EUT defined as follows:

Performance Criterion A (For continuous phenomena): The Equipment Under Test shall continue to operate as intended during and after the test. The degradation of performance or loss is allowed as defined in the technical specification published by the manufacturer.

Performance Criterion B (For transient phenomena): The EUT shall continue to operate as intended after the tests. No degradation of performance or loss of function is allowed as defined in the technical specification published by the manufacturer. During the test, degradation or loss of function or performance which is self recoverable is however allowed but no change of actual operating state or stored data is allowed.

Performance Criterion C: Temporary degradation or loss of function or performance is allowed during the test, provided the function is self recoverable, or can be restored at the end of the test by the operation of the controls, as defined in the relevant equipment standard and in the technical specification provided by the manufacturer.
