    Preparation of Test Equipment

    Before conducting a test, laboratory personnel prepare specialized test equipment, including:

  • Power supplies with high accuracy voltage regulation

  • Measuring instruments, such as oscilloscopes or spectrum analyzers

    • Setup of Test Configuration

    The test configuration is set up to simulate the conditions under which the electrical device will operate. This includes:

  • Connecting the power supply and measuring instruments

  • Setting up the test configuration according to IEC 61000-3-3 requirements

    • Measurement and Analysis

    Measurements are taken using specialized equipment, such as oscilloscopes or spectrum analyzers.

    1. Measure the voltage output of the power supply

    2. Measure the current drawn by the device under test (DUT)

    3. Analyze the data to determine whether the DUT meets the requirements specified in the IEC 61000-3-3 standard

    Interpretation of Results

    The results are interpreted according to the guidelines specified in the IEC 61000-3-3 standard.

    Test Report and Certificate

    A test report is issued, detailing the results of the testing. A certificate may also be issued, indicating compliance with the standard.
