  • Current Caliper

    KH23101 - Beijing KeHuan Century EMC Technology Co,.LTD

    The KH23101 current caliper is a toroidal transformer used to measure EMI current. When measuring, the caliper does not directly touch the electrical conductor or the cable under test. The conductor passing through the caliper window is used as the single-turn primary wire of the transformer, and the secondary is designed to be multi-turn. Use with 50 Ω receiving system (such as EMI electromagnetic interference field strength meter or spectrum analyzer). In order to facilitate installation and rapid measurement of EMI current, it is designed as a caliper that can be opened.

  • Voltage Probe

    KHZ43201 - Beijing KeHuan Century EMC Technology Co,.LTD

    The KHZ43201 voltage probe is a standard low resistance test probe, which meets the technical requirements for this product in the CISPR16-1 and CISPR14-1 test equipment. When measuring the interference voltage of the power grid, the artificial power supply network cannot be used at the load port, and sometimes it is necessary to use a voltage probe to measure the interference of the signal port, the load port, and the antenna port. The input impedance of the voltage probe to the ground wire is greater than 1.5KΩ, which can protect the input terminal of the receiver.
