Test Report #EMCC—9%80162 1EA Page 7 of 17 Issue Date: 2003—AUG—20 Test of Conti Temic GmbH Type ARS 2—B, Serial number 4585¥4 to 47 CFR Part 15C — Intentional Radiators, §15.253 4 RADIATED EMISSIONS Test Requirement: FCC CFR47, Part 15C Test Procedure: ANSI C63.4:1992 4.1 Regulation Section 15.253 Operation within the bands 46.7—46.9 GHz and 76.0—77.0 GHz. (a) Operation within the bands 46.7—46.9 GHz and 76.0—77.0 GHz is restricted to vehicle—mounted field disturbance sensors used as vehicle radar systems. The transmission of additional information, such as data, is permitted provided the primary mode of operation is as a vehicle—mounted field disturbance sensor. Operation under the provisions of this section is not permitted on aircraft or satellites. (b) The radiated emission limits within the bands 46.7—46.9 GHz and 76.0—77.0 GHz are as follows: (1) If the vehicle is not in motion, the power density of any emission within the bands specified in this section shall not exceed 200 nW/cm at a distance of 3 meters from the exterior surface of the radiating structure. (2) For forward—looking vehicle—mounted field disturbance sensors, if the vehicle is in motion the power density of any emission within the bands specified in this section shall not exceed 60 uW/cm* at a distance of 3 meters from the exterior surface of the radiating structure. (c) The power density of any emissions outside the operating band shall consist solely of spurious emissions and shall not exceed the following: (1) Radiated emissions below 40 GHz shall not exceed the general limits in Section 15.209 of this part. (2) Radiated emissions outside the operating band and between 40 GHz and 200 GHz shall not exceed the following: (ii) For forward—looking vehicle—mounted field disturbance sensors operating in the band 76—77 GHz: 600 pW/icm* at a distance of 3 meters from the exterior surface of the radiating structure. (3) For radiated emissions above 200 GHz from field disturbance sensors operating in the 76—77 GHz band: the power density of any emission shall not exceed 1000 pW/cm* at a distance of 3 meters from the exterior surface of the radiating structure. (4) For field disturbance sensors operating in the 76—77 GHz band, the spectrum shall be investigated up to 231 GHz. (d) The provisions in Section 15.35 of this part limiting peak emissions apply. (e) Fundamental emissions must be contained within the frequency bands specified in this section during all conditions of operation. Equipment is presumed to operate over the temperature range —20 to +50 degrees Celsius with an input voltage variation of 85% to 115% of rated input voltage, unless justification is presented to demonstrate otherwise.

(b) On any frequency of frequencies above 1000 MHz, the radiated limits shown are based upon the use of measurement instrumentation employing an average detector function. When average radiated emission measurements are specified in the regulations, including emission measurements below 1000 MHz, there is also a limit on the radio frequency emissions, as measured using instrumentation with a peak detector function, corresponding to 20 dB above the maximum permitted average limit for the frequency being investigated unless a different peak emission limit is otherwise specified in the rules in this part, e.g., see § 15.255. Unless otherwise specified, measurements above 1000 MHz shall be performed using a minimum resolution bandwidth of 1 MHz. Measurement of AC power line conducted emissions are performed using a CISPR quasipeak detector, even for devices for which average radiated emission measurements are specified. Section 15.209 (a) Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in the following table: Frequency Field Strength Measurement distance (MHz) (microvolts/meter) ({meters) 0.0093—0.490 2400/F(KHz) 300 0.490—1.705 24000/F(KHz) 30 1.705—30.0 30 30 30—88 100 3 88—216 150 3 216—960 200 3 Above 960 500 3 (b) In the emission table above, the tighter limit applies at the band edges. (c) The level of any unwanted emissions from an intentional radiator operating under these general provisions shall not exceed the level of the fundamental emission. For intentional radiators which operate under the provisions of other sections within this part and which are required to reduce their unwanted emissions to the limits specified in this table, the limits in this table are based on the frequency of the unwanted emission and not the fundamental frequency. However, the level of any unwanted emissions shall not exceed the level of the fundamental frequency. (d) The emission limits shown in the above table are based on measurements employing a CISPR quasi peak detector except for the frequency bands 9—90 kHz, 110—490 kHz and above 1000 MHz. Radiated emission limits in these three bands are based on measurements employing an average detector. (e) The provisions in §§ 15.31, 15.33, and 15.35 for measuring emissions at distances other than the distances specified in the above table, determining the frequency range over which radiated emissions are to be measured, and limiting peak emissions apply to all devices operated under this part.

Floor standing equipment is placed directly on the flush mounted metal turntable. The EUT is connected to its associated peripherals with any excess I/O cabling bundled to approximately 1 meter. The EUT was tested as a tabletop equipment, connected with peripherals as described in chapter 2.2. The tests were performed in one mode as described in chapter 2.3. The initial step in collecting radiated data is a peak scan of the measurement range with an EMI test receiver under closer distances as given in the rule. The significant peaks are then measured with the appropriate distance and detectors. Worst case radiated emissions are listed under chapter: test results. > The end frequency 26.5 GHz of this chapter was selected because of the end frequency of the coaxial RF input of the spectrum analyzer used as test receiver.

Above 26.5 GHz additional external mixers have to be used, which results in additional correction factors. Due to high mixer loss at very high frequencies the distance between the EUT and the test antenna was reduced to very low values (some cm) to detect any emissions. The operating band 76 GHz to 77 GHz was excluded.

The basic equation with a sample calculation is as follows: j FS = RA + AF + ML where FS = Field Strength in dBuV/m RA = Receiver Amplitude in dBpV AF = Antenna Factor in dB(1/m) ML = Mixer Loss in dB Assume a receiver reading of 10.2 dBuV is obtained. The Antenna Factor of 38.8 dB(1/m) and a Mixer Loss of 22 dB are added, giving a field strength of 71 dBpV/m. The 71 dBuV/m value can be mathematically converted to its corresponding level in uV/m. FS =10.2 + 38.8 + 22 = 71 [dBpV/m] Level in uV/m = Common Antilogarithm (71/20) = 3,548 For test distance other than what is specified, but fulfilling the requirements of Section 15.31 (f)(1) the field strength is calculated by adding additionally an extrapolation factor of 20 dB/decade (inverse linear— distance for field strength measurements). The basic equation with a sample calculation is as follows: FS = RA + AF + ML + DF where FS = Field Strength in dBuV/m RA = Receiver Amplitude in dBuV AF = Antenna Factor in dB(1/m) ML = Mixer Loss in dB DF = Distance Extrapolation Factor in dB, where DF = 20 log (Dtest/Dspec) where Dtest = Test Distance and Dspec = Specified Distance. Assume the tests performed at a reduced Test Distance of 1 m instead of the Specified Distance of 3 m giving a Distance Extrapolation Factor of DF = 20 log(1m/3m) =—9.5 dB. Assuming a receiver reading of 10.2 dBuV is obtained. The Antenna Factor of 38.3 dB(1/m), the Mixer Loss of 22 dB and the Distance Factor of —9.5 dB are added, giving a field strength of 61.5 dBpV/m. The 61.5 dBuV/m value can be mathematically converted to its corresponding level in uV/m. FS = 10.2 + 38.8 + 22 — 9.5 = 61.5 [dBuV/m] Level in uV/m = Common Antilogarithm (61.5/20) = 1,188 ARS 2 B FCC IEA.DOC

The basic calculation is similar as described in the chapter above with the difference, that the result is the power density: PD = RA + ML + DF — A where PD = Power Density in dBm/cm*, RA = Receiver Amplitude in dBm, ML = Mixer Loss in dB, DF = Distance Extrapolation Factor in dB, A = effective Antenna Aperture in dB(cm?) where DF = 20 log (Dtest/Dspec) where Dtest = Test Distance and Dspec = Specified Distance, and A = 10 log (effective Antenna Aperture in cm*). For an assumed result of —60 dBm/cm* the level in pW/cm* is: 10° x Common Antilogarithm (—60/10) = 1,000 4.3.6 Test Results Device: Adaptive Cruise Control Pulse Doppler RADAR System Type: ARS 2—B Serial number: 458544 PRODUCT EMISSIONS DATA, 26.5 GHz < f < 40 GHz No Emission Receiver Test Receiver Antenna Mixer Distance Result= Spec Polarization Margin Frequen— Mode and Distan— Reading Factor Loss Extrapola Corrected Limit cy Bandwidth ce tion Factor Reading Ant RA AF ML DF FS [MHz] [kHz] {m] [dBuV] [dB(1/m)] [dB] [dB] {dBpV/m] [dBuV/m] {dB] No emissions found above noise within this frequency band LC_—CITT——TIT—— 44— T TT ARS 2 B FCC IEA.DOC
