Vehicle Electromagnetic Field Test System
-
Beijing KeHuan Century EMC Technology Co,.LTD
Vehicles are the daily means of transportation for our public, and the electromagnetic pollution in vehicles has received more and more attention from the public. The newly revised mandatory standard GB27630-201X "Air Quality Evaluation Standard for Passenger Cars" intends to require the electromagnetic field in the vehicle as one of the indicators. The measurement method measures the magnetic field strength in the vehicle. Within the frequency range of 10Hz-400kHz, the electromagnetic field measurement results should meet the requirements of the public limit of electromagnetic exposure in GB8702-2014.

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.

Active Dual Loop Antenna
KH30936
-
Beijing KeHuan Century EMC Technology Co,.LTD
KH30936 active dual loop antenna is used for adjusting, testing, measuring and other receivers. It has many advantages:1. The antenna coverage frequency is wide: 150KHz ~ 30MHz .2. The field strength value is measured according to the correction coefficient within the effective frequency range, which is convenient to use.3. The antenna power is supplied by the host, which is convenient for outdoor measurement.4. Compared with the single loop antenna, the advantage is to read the maximum value directly, which eliminates the tedious steps of rotating the antenna to find the maximum value and the interference of the human body to the signal.
