1.0 TEST STANDARDS / DOCUMENTS

1.1 The following documents were applicable to the preparation and performance of the EMC tests 

discussed:

RTCA/DO-160G: Electromagnetic Emission and Susceptibility Requirements for the Control of 

Electromagnetic Interference

Other Documents: None

2.0 SUMMARY

2.1 Description of Equipment under Test::

Caire Model 4000 Portable Oxygen Concentrator.

2.2 Power Requirements:

The EUTs were designed to operate with internal battery for normal operational modes.

The EUT was not tested in charging mode as this is not a operational condition aboard aircraft.

2.3

Deviations from the Test Plan:

None

2.4 Recommendations.

None

2.5 TEST SPECIFICATION DEVIATIONS: 

Additions To: None

Exclusions From: None

3.0 STATEMENT OF MEASUREMENT UNCERTAINTY

The data and results referenced in this document are accurate. The reader is cautioned that there is some 

measurement variability due to the tolerances of the test equipment that can contribute to a nominal product 

measurement uncertainty. Furthermore, component differences and manufacturing process variability of production 

units similar to that tested may result in additional product uncertainty. If necessary, refer to the test lab for the 

actual measurement uncertainty for specific tests.

4.0 MODIFICATIONS REQUIRED TO PASS:

No modifications were implemented.

5.0 TEST CONFIGURATION AND GENERAL TEST PROCEDURES .

5.1 Description of Test Site

The testing was performed at TÜV SÜD America, Inc., San Diego, California, within a Shielded Room, 20’ 

x 28’ x 16’, Metal, Semi-Anechoic Chamber.

5.2 Sequence of Testing

The test sequence was followed per the test engineer’s discretion.

5.3 Ambient Measurements

Ambient surveys were performed to establish background noise levels where needed. For each ambient 

survey, EMI test equipment configuration was as it would be for the test. Receiver sweep speed, 

bandwidth, etc. was the same during the ambient survey as during testing. The frequency range for each 

test method was swept and measured levels recorded. As a minimum, ambient levels were 6 dB below the 

applicable test limit.

5.4 Instrumentation

Calibration intervals and requirements of all measurement instrumentation used were in accordance with 

ANSI/NCSL Z540-1-1994. All instruments and model numbers used during testing are listed in each test 

section.

5.5 Table 1: Test Summaries and Results lists the EMI/EMC tests performed and the compliance results.

6.0 TEST SPECIFICATION DEVIATIONS: 

Additions To: None

Exclusions From: None

7.0 STATEMENT OF MEASUREMENT UNCERTAINTY

The data and results referenced in this document are accurate. The reader is cautioned that there is some 

measurement variability due to the tolerances of the test equipment that can contribute to a nominal product 

measurement uncertainty. Furthermore, component differences and manufacturing process variability of 

production units similar to that tested may result in additional product uncertainty. If necessary, refer to the test 

lab for the actual measurement uncertainty for specific tests.

8.0 MODIFICATIONS REQUIRED TO PASS:

Oscillator crystals were grounded.

9.0 GENERAL CONFIGURATION AND BONDING TEST PROCEDURES

9.1 Electrical Bonding

A ground plane, having physical and electrical characteristics as defined in RTCA/DO-160G, was used to 

electrically bond the test sample to the shielded enclosure. Bond resistance between the test sample and ground 

plane satisfied the resistance requirements for Class R bonds per ANSI-NCSL Z540-1-1994 (i.e., 2.5 mΩ or less). 

Each time the test sample was repositioned bond resistance was verified and recorded. No physical bonding to the 

EUT is possible.

9.2 Test Configuration

The general EMI/EMC test configuration was as shown in photographs for each setup.
