Vehicle Electromagnetic Field Exposure Test System
SEM-400
Beijing KeHuan Century EMC Technology Co,.LTD
Vehicles are our daily public transportation. Electromagnetic pollution in vehicles has attracted more and more public attention. The newly revised compulsory standard GB27630-201X "Passenger Car Air Quality Evaluation Standard" intends to require the electromagnetic field in the car as one of the indicators, according to GB/T37130-2018 "Measurement method of vehicle electromagnetic field relative to human exposure" The measurement method is to measure the intensity of the magnetic field in the car. In the frequency range of 10Hz-400kHz, the electromagnetic field measurement result should meet the public limit requirements of GB8702-2014 for electromagnetic exposure.

Electrostatic Discharge Generator
STT-ESD-2005
Beijing KeHuan Century EMC Technology Co,.LTD
Is a tester that meets the requirements of IEC61000-4-2 and GB/T17626.2. Its maximum electrostatic discharge voltage can reach 30kV, covering the electrostatic voltage requirements in the standard (the electrostatic voltage requirement for the fourth level of air gap discharge is 15kV), and it is suitable for more application fields and the requirements of future new standards. Therefore, the ESD-2005 electrostatic discharge generator can be used for most electrical and electronic equipment electrostatic discharge tests, and can ensure the comparability and reproducibility of the test.

Log-Periodic Antenna
KH30937F
Beijing KeHuan Century EMC Technology Co,.LTD
KH30937F log-periodic antenna (hereinafter referred to as KH30937F ) is a linearly polarized broadband receiving antenna with a working frequency of 30MHz~1GHz . KH30937F has excellent standing wave ratio characteristics, accurate feeding position, and the best phase relationship between each period on the base. The antenna gain is basically constant, thus ensuring that the antenna factor changes linearly and smoothly with the frequency, which is helpful for accurate difference calculation between each frequency point.

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.

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.
