ABSTRACT

This report presents test results of emanations found emitting from the Rockwell

Collins DME-4000 and the comparison of these emissions to the requirements of FCC,

Title 47, Part 15, Subpart C for spurious radiated emissions.

This testing was performed on a 3 meter open area test site at Rubicom

Systems, Inc. (RSI). The testing was performed for Rockwell Collins, Inc. under

purchase order 4500585492 and is filed under JA-1869 at RSI. The results of this test

effort demonstrate compliance of the Rockwell Collins, DME-4000 to FCC, Title 47, Part

15, Subpart C intentional radiators.

Equipment under test (EUT) was a Rockwell Collins DME-4000 Transceiver, s/n:

GK4H.

1.0 INTRODUCTION

1.1 Purpose

The purpose of this report is to show compliance of the Rockwell Collins,

Inc. Model DME-4000 to the requirements of Part 15 of the FCC Rules and Regulations

(47CFR, Part 15, Subpart C) for intentional radiators. The tests were performed on a 3

meter site.

1.2 Requirements

The test requirements are as follows:

RADIATED RX MODE (15.209A)

Frequency 3 Meter 3 Meter
(MHz) Field Strength (dBµV/m)
(µV/m)
30 - 88 100 40
88 - 216 150 43.5
216 - 960 200 46
960 - Above 500 54 Avg.
74 Peak

CONDUCTED TX MODE (CFR 87)

Harmonics of transmitter attenuated by at least 20dB. This test was

performed as a conducted test on the antenna port up to the 10th harmonic. No signals

appear at the antenna port other than the intended transmit signal.

1.3 Equipment Under Test

The DME-4000 Transceiver is a remote mounted unit which measures

the slant range (line-of-sight) distance from the aircraft to the ground station and outputs

digital distance data in nautical miles for display on a companion indicator, HIS, or EFIS

display. In addition, the system computes the relative closure rate and time to station

(TTS), and provides a decoded station identifier.

1.4 Summary of Results

Results are presented in Paragraph 6.0. The DME-4000 meets the

requirements stated in Paragraph 1.2.

2.0 APPLICABLE DOCUMENTS

The following documents form a part of this report to the extent expressed

herein:

FCC Code of Federal Regulations Title 47, Part 15

3.0 TEST SITE DESCRIPTION

This testing was performed at Rubicom Systems, Inc. 3 meter open area

test site. The description of the measurement facility was found to be compliant with the

requirements of Section 2.948 of the FCC rules. A copy of the compliance letter is

attached to this report as Appendix A.

3.1 Environmental Conditions

Environmental conditions during testing of the EUT were as follows:

Date: November 5, 2001

Temperature: 83º

Barometer: 29.35 inches

Humidity: 70%

5.0 TEST SAMPLE SETUP AND CONFIGURATION

The Rockwell Collins, Inc. DME-4000 was placed on the nonconductive

80cm high manual turntable. The unit was configured with a DC power supply. The

antenna port was connected to an IFR model ATC1400 DME test set (located 20 ft.

from the EUT. The system cable was coiled on the table with the EUT and power

supply.

6.0 PROCEDURES AND RESULTS

6.1 Radiated Emissions

The transmitter was operated at 1150MHz for the radiated emissions.

The measurements were performed from 30MHz to 12GHz. Only one signal was found

at 35.9MHz and measured 6dB below the limit in the vertical polarization. Data Sheets

6.1-1 through 6.1-14 present the quasi-peak sweeps to 1GHz and average and peak

sweeps from 1-12GHz.

Data Sheets 6.1-15 through 6.1-28 present the ambient data over the

30MHz-12GHz frequency range.

6.2 Spurious Emissions (Transmitter)

Spurious emissions were measured at the antenna port to prove the

harmonic attenuation to be 20dB below the fundamental as required in Part 87. Data

Sheets 6.2-1 and 6.2-2 present the levels for the fundamental and up to the 10th

harmonic. The transmitter frequency was tested at a low channel 1025MHz, mid

channel 1080MHz and high channel 1150MHz.

6.3 Results

No signals were found to be above the requirements for radiated or

spurious emissions. No modifications were required.

6.4 Preliminary Scans

Data Sheets 6.4-1 through 6.4-8 are plots made inside the shielded

enclosure for frequency identification of signals that were emitted without the ambient

interference.
