Anechoic Chamber Test software: Test system test results meet the standard requirements: Pass Test position: Positive power cab^ Negative power cable. Test configuration Test Procedure: a> The test equipment is powered on for preheating and reaches a stable operating state; K Perform the verification by applying 1kHz, 3kHz, and 10kHz verification signals to the current probe, with the signal level being 6dB below the standard limit value; c> Measure the current level using an oscilloscope and a resistor, while checking if the current GRG Metrology & Test Group Co.,Ltd Address: No.8, Chuangyun...

waveform is a sine wave; d^ The measurement receiver scans in the normal data scanning mode, confirming that the measurement value of the measurement receiver is within the ±3dB range of the oscilloscope current measurement value. If the measurement value deviates by more than ±3dB, the error cause must be identified and corrected. e> Configure the test according to Figure CE101-2; f The test sample is powered on for preheating to achieve a stable operating condition; g^ Select a power cord and clip the current probe onto the power line to be tested; h Using the bandwidth and minimum measurement...
