CA HFK

Calibration Kit for Capacitive Coupling Clamp verification

 
  • Descriptions

    The IEC 61000-4-4 Ed 3.0 published 2012 recommends the calibration of the capacitive coupling clamp into a 50ohm coaxial load.
    The capacitive coupling clamp (HFK) is connected to the 50 ohm output of the EFT generator. A flexible insulated plate inside the HFK is connected to a coaxial 50 ohm load resistor for verificate the EFT / Burst wave of the capacitive coupling clamp.
  • Highlights

    - Calibration kit for capacitive coupling clamp as per IEC 61000-4-4 Ed.3
    - Extension for the CA EFT Kit for capacitive coupling clamp calibration with EFT/burst
    - Flexible transducer plate 1050 x 120mm included
    - Support provided to adapt the load resistors on 100mm height level
  • Benefits

    Calibration of the capacitive coupling clamp
    The standard IEC 61000-4-4 Ed 3.0 recommends a new calibration of the capacitive coupling clamp. EM test developed for the calibration, the CA HFK set.

    Components required for carry out the calibration:
    CA HFK: Consisting of transducer-plate and support
    KW 50: Load resistor 50ohm
    AD-CA EFT: Adapter 4mm/6mm for connect the transducer-plate to the coaxial F103 connector of KW 50

    Calibration set-up
    The transducer plate shall be placed into the capacitive coupling clamp such that the end with the connection is aligned with the end of the coupling plate. The connecting adapter AD-CA EFT is bond with a low impedance connection band to ground reference plane for grounding of the 50ohm coaxial measurement terminator/attenuator. The load resistor KW 50 is connected to the AD-CA EFT adapter. An acrylic support places the KW 50 to the same 100mm height as the coupling clamp is distant from the reference ground.
    The distance between the transducer plate and the KW 50 measurement terminator/attenuator shall not exceed 0,1m. A setup example is given in figures on this datasheet.
     



    Coupling Clamp calibration
    Simplified diagram KW 50ZoomThe calibration of the capacitive coupling plane is performed with the open circuit voltage setting at the EFT/burst generator (50ohm output): 2,000V
    Resulting output voltage across the KW 50
    (50ohm matching resistor): 1,000V.
    Measuring voltage Vm: 10V
    Measured voltage considering the 50ohm input impedance of the oscilloscope: 5V
