1、GM DAEWOO Auto the test item must be decided under conference between the designer and real tester. 3.2.1.1. Radiated Emission Component Test This test can be proceed at either Anechoic Chamber or Reverberation Lab. 3.2.1.1.1. Reverberation Chamber Test 3.2.1.1.1.1. Purpose This test is to measure t
2、he radioactive wave from Electric/Electronic component and Sub-system to protect Receiver from its harm. 3.2.1.1.1.2. Test Equipment . Receiver: Use Spectrum Analyzer or equivalence Receiver. . Preamplifier/Pre-selector: Use equipments to elevate the sensitivity to the smallest amount of Signal. . A
3、ntenna: Use below Antennas according to given Frequency, and must use different Antenna according to Frequency range. z Active Monopole(Emco 3301B or equivalence specification) : Frequency Range : 150 khz 20 Mhz Reference Point: Surface authorize transited current to DUT wire. Monitor Current Probe
4、 This probe covers the DUT wire and monitors authorization of real induced current. 6.2. Abbreviated Word Aperiodic (noncompliance)frequency during the test should be rejected just as Aperiodic (noncompliance)frequency in a real car test. From the experience, repeated maximum output ratio for amplifier can be fatal to its life span. Therefore, purchased amplifier must have higher output ratio then the asking maximum output ratio. The Harness which connects inside of simulator and the DUT should be long enough to avoid negative effect from electromagnetic during electromagnetic field test.
