2 T CAS FCC Compliance Test Report SPEC NO: 8000709-001 REV LTR CAGE CODE: 1WYD3 - 6 FCC COMPLIANCE TEST PLAN 6.1 FCC Compliance Overview The Code of Federal Regulations, Title 47, Volume 1, Part 2, Subpart J (47CFR2.xxxx) provides procedures for radio frequency equipment to be authorized by the FCC. Certification is an equipment authorization issued by the commission, based on representations and test data submitted by the applicant. Certification attaches to all units subsequently marketed by the grantee which are identical (see section 6.1.2) to the sample tested except for permissive changes or other variations authorized by the commission. 6.1.1 FCC Identifier 47CFR2.924 states that equipment, which has been authorized by the FCC, bears an FCC Identifier. Equipment, which has been authorized, may be marketed under different model/type numbers or trade names without additional authorization from the commission, provided that such devices are electrically identical and the equipment bears an FCC Identifier validated by a grant of equipment authorization. 6.1.2 Changes in Certified Equipment 47CFR2.907, 8 defines Identical as either being units whose variances fall within those expected to arise as a result of quantity production techniques, or those that have been changed where the change meets the criteria of a permissive change. 47CFR2.1043 states that changes to the basic frequency determining and stabilizing circuitry (including clock or data rates), frequency multiplication stages, basic modulator circuit or maximum power or field strength ratings shall not be performed without application for and authorization of a new grant of certification. Variations in electrical or mechanical construction, other than the above indicated items, are permitted provided the variations either do not affect the characteristics required to be reported to the commission or are made in compliance with other provisions in 47CFR2.1043 Two classes of permissive changes may be made in certified equipment without requiring a new application for and grant of certification. Neither class of change shall result in a change of identification. • A Class I permissive change includes those modifications in the equipment that do not degrade the characteristics reported by the manufacturer and accepted by the commission when certification is granted (i.e., power, frequency, etc.). No filing with the commission is required for a Class I permissive change. •A Class II permissive change includes those modifications that degrade the performance characteristics as reported to the commission at the time of initial certification.

2 T CAS FCC Compliance Test Report SPEC NO: 8000709-001 REV LTR CAGE CODE: 1WYD3 - 6.2 T 2CAS Units Similarity to Predecessor TCAS-2000 Unit 2 2 The T CAS units evolved from the predecessor TCAS-2000 unit. The T CAS units utilize the same TCAS circuit boards and TCAS circuit board software that the predecessor TCAS-2000 units utilize. These TCAS circuit boards have been previously certified with the FCC in the 2 predecessor TCAS 2000 unit. This T CAS model is powered exclusively from a DC power source. 6.3 T 2CAS Model to be Subjected to FCC Compliance Testing 2 The T CAS model TT-952 unit will be subjected to the full suite of FCC compliance tests with the 2 resulting data submitted to the FCC for certification. Test results from the T CAS model TT-952, 2 other than Radiated Emissions, will be credited to T CAS model TT-951 for submittal to FCC for 2 certification. The T CAS model TT-951 unit will be subjected to the Field Strength of Spurious Radiation tests to verify that its smaller 4MCU chassis with a fan does not alter emissions characteristics 6.4 All Three T 2CAS Models Considered Identical 2 For purposes of FCC compliance testing and certification, T CAS models (TT-951 and TT-952) 2 are considered to meet the FCC definition of “Identical.” Photographs of the T CAS unit illustrating the assembly drawings, including markings, are shown in Figures 3 – 18. All original 2 photographs are available for inspection. Differences exist between the two T CAS models, however these differences fall within the definition of a Class I permissive change because the items which provide the transmit and receive functions (the TCAS circuit boards and their 2 software) are the same in the two T CAS models. 6.4.1 Conclusion 2 The full suite of FCC compliance tests was performed on a T CAS model TT-952 unit. The 2 T CAS model TT-951 unit will be subjected to the Field Strength of Spurious Radiation tests. Test data from both TT-951 and TT-952 FCC compliance tests will be submitted to the FCC to 2 apply for a new certification and FCC identifier for the T CAS model TT-951units.
