QU EL LE : N OL IS Page 2 TL 965: 2006-11 ─ introduction of testing philosophy acc. to CISPR 25 (test sequence Figure 1- extended by test sequence Figure 2) ─ revision and adaptation of tables specifying limit values to CISPR 25, Edition 3.0 – (Committee Draft 2006-05-05) Previous issues 1976-01, 1979-04, 1983-04, 1987-06, 1994-03, 1999-11, 2003-06, 2004-10 1 Scope This TL standard specifies requirements and tests regarding electromagnetic compatibility (EMC) with the aim of limiting interference emissions (radio interference suppression) of electric and elec- tronic automotive components. The measuring methods and limit values specified in this TL stan- dard are designed to ensure an interference-free reception of the high-frequency receivers oper- ated in the vehicle. The measuring methods and limit values described in this TL standard shall apply to all electric and electronic automotive components. Depending on the radio application in the vehicle, tests shall be carried out in the specific frequency bands for radio and TV broadcasting, mobile phone and mobile radio between 70 kHz and 2,5 GHz. A release is issued if component and vehicle tests yielded positive results. The measuring methods, conditions and measuring setups specified in this TL standard comply to a large extent with the international standardization according to CISPR 25, Edition 3.0 – (Commit- tee Draft 2006-05-05), which may be referred to in this document and which, in addition, represents the source documentation from which aforementioned methods, conditions and setups were taken with respective modifications. However, the specifications contained in this TL standard shall take precedence over the specifications in the above mentioned CISPR 25. 2 Definitions See CISPR 25, Edition 3.0 – (Committee Draft 2006-05-05), Section 3. In addition: 2.1 Short-term interference sources – permanent interference sources Interferences that are not explicitly defined as short-term interference sources by the responsible engineering department are considered as permanent interference sources and shall be sup- pressed. Frequency ranges affected by this regulation must be specified in the component per- formance specifications by the EMC engineering departments. 3 General requirements for interference emission measurements on vehicles and components See CISPR 25, Edition 3.0 – (Committee Draft 2006-05-05), Section 4. In addition to and/or devia- ting from this: 3.1 Temperatures Operating temperature range acc. to drawing, Performance Specifications or TL standard Test temperature range (23 ± 5) °C; operating temperature in special cases 3.2 Run-in time The electric devices under test (DUT) are subjected to a 15-minute run-in time under specified load (acc. to drawing or Performance Specifications) and test voltage. Page 3 TL 965: 2006-11 3.3 Frequency ranges Vehicle measurement 70 kHz to 2 500 MHz Component measurement using artificial network 150 kHz to 108 MHz Component measurement in the TEM cell without absorber elements 150 kHz to 200 MHz Component measurement in the TEM cell fitted with absorber elements 150 kHz to 400 MHz Component measurement in the anechoic chamber 150 kHz to 2 500 MHz Appendix A: Stripline component measurement 30 MHz to 400 MHz 3.4 Description of the operating states The different operating and worst-case states of the DUT shall be presented by the supplier in ad- vance; their influences on the interference emission shall be analyzed in consultation with the re- sponsible Volkswagen Group engineering departments. The responsible Volkswagen Group EMC engineering department decides on the importance of individual operating states for testing within the framework of the EMC concept discussion, which must be held according to the EE Perform- ance Specifications. On principle, component testing acc. to Section 5 shall be conducted by the supplier. In order for component testing to be verified by a Volkswagen Group EMC engineering department, the supplier must provide appropriate test equipment allowing, at least, for the simulation of the worst-case operating states as well as for the monitoring of these states during testing. The tested operating states and test setups must be documented in the EMC qualification report. 3.5 Test documentation In order for the EMC relevance to be tested, the following mandatory documents must be pre- sented upon commencement of development: ─ system designation ─ system description including representation of system functions ─ circuit diagram, component location drawing and bill of materials ─ operating states with sequence descriptions (e.g. switch-on/-off procedures, static/dynamic states) ─ description of sub-circuitry (sub-systems, sensors, actuators) ─ system variants and codings ─ interfaces to other vehicle components ─ system-inherent fault handling and diagnostic function ─ documentation of the EMC measures (e.g. filter and protective circuitry for inputs/outputs as well as supply lines, screening measures) Prior to delivery of the samples to be tested, the following documents shall be presented in addi- tion: ─ deviations from TL specifications as agreed upon between Volkswagen Group engineering departments and supplier ─ meaningful, complete EMC qualification report for the respective sample version ─ hardware/ software version including description/record of the EMC measures Page 4 TL 965: 2006-11 3.6 Test sequences Figure 1 – Test sequence for frequency range 70kHz to 2,5GHz (exception LW-MW-SW-FM) transmitting antenna Page 5 TL 965: 2006-11 no Start Are the average data below the average limit value? Measurement using quasi-peak detector – only for frequencies where peak data exceed the quasi-peak limit value Fail Pass no Limit values for average, peak and quasi-peak shall be complied with Measurement using average detector Measurement using peak detector Are the peak data below the peak limit value? Are the quasi-peak data below the quasi-peak limit value? yes yes yes no Since values acquired in peak measurements are always at least as high as values acquired in quasi-peak measurements, the measuring time can be considerably reduced by this procedure. As a consequence, measurements using the quasi-peak detector can be reduced to a minimum. If not otherwise defined, the limit values for all three detector types (average, peak and quasi-peak) must be complied with in the following frequency ranges: - LW - MW - SW - FM Figure 2 – Test sequence for broadcasting ranges LW-MW-SW-FM Page 6 TL 965: 2006-11 4 Measurement of interference emissions on the vehicle See CISPR 25, Edition 3.0 – (Committee Draft 2006-05-05), Section 5.

Mounting location of receiving antenna Page 8 TL 965: 2006-11 4.4 Measurement of active antenna noise GENERAL INFORMATION: If power supply is required, the antenna adapter (dummy) shall be powered by accumulators. The use of active antennae may lead to an increase in background noise. This additional noise generated by the antenna amplifier depends on the type of antenna used. The actual interference is calculated using formula 1: 22 noise antenna valuemeasured ceinterferen actual UUU −= | values in (µV) Instructions for determining the noise of active vehicle antennae in the AM and FM band Three steps are necessary to determine the antenna noise of active antennae. 1. Measurement of the background noise of the measuring equipment = (Uequipment noise ): (measuring receiver plus antenna dummy), see measuring setup in Figure 4. 2.

The dum- my's output impedance must be 50 Ω. In order to avoid interferences coupled into the measuring receiver by external sources, the following boundary conditions must be taken into consideration: In principle, the radio dummy (the antenna adapter) shall be powered internally using accumulators and shall be placed inside the vehicle such that it is insulated from the vehicle body. In cases where the radio dummy (the antenna adapter) is to be powered by means of the vehicle power supply system, an input filter circuit corresponding to the radio shall be connected into the dummy's power supply input. The measuring receiver shall be completely decoupled from the chamber shield (if necessary, op- erated
