    • 品牌: EM TEST

      HFK is used to couple electrical fast transients/bursts to I/O lines, which meets the requirements of European and international standards for immunity testing.

      Applying electrical fast transients/bursts to signal lines is usually not possible through discrete capacitive coupling without disturbing the signal flow. It is usually not possible to have direct access to the cables to be tested, such as coaxial or shielded cables. The solution of EM TEST is to connect the interference simulator to both ends of the capacitive coupling clamp, and realize the coupling through the capacitive coupling clamp.

      According to the requirements of IEC 61000-4-4 standard Ed 3.0 promulgated in 2012, the calibration of the capacitive coupling clamp is completed by the standard calibration component ICC PVKIT 1 with a 50 ohm coaxial load.

      CCI PVKIT 1 Calibration Setup:

      Calibration of Capacitive Coupling Clamp

      IEC 61000-4-4 Standard Ed 3.0 recommends calibration of capacitive coupling clamps. EM TEST developed and designed the CCI PVKIT 1 calibration component according to the standard requirements.

      Calibration requires the following facilities:

      CCI PVKIT 1: with sensor board and support accessories

      PVF 50: 50 ohm load resistance

      PVF AD 3: 4 mm adapter for connecting the connection sensor board to the SHF coaxial connector of the KW 50

    Calibration settings:

      The sensor board should be placed in the capacitive coupling clamp with the end of the connection adapter aligned with the edge of the coupling board. Connect the connection adapter PVF AD 3 with a low-impedance connection strap to the ground reference plane of the 50 ohm coaxial measurement terminal/attenuator. Connect the load resistor KW 50 to the AD-CA EFT adapter. Use the acrylic support attachment to position the PVF 50 at the same height as the coupling clamp, 100 mm from the ground reference plane.

      The distance between the sensor board and the PVF 50 measuring terminal/attenuator should be less than 0.1 m.

      This technical data sheet gives a schematic diagram of the setup.

    Calibration of the coupling clamp:

      For calibration of the capacitive coupling plane, the open circuit voltage of the EFT/burst generator (50 ohm output) needs to be set to: 2,000 V

      Resulting output voltage value across PVF 50 (50 ohm matching resistor): 1,000 V

      Measuring voltage Vm: 10 V

      Under 50 ohm input impedance, the voltage value measured by the oscilloscope: 5 V

      Resulting attenuation (theoretical): 400:1
