Introduction：
The CNA 280 is a coupling and decoupling network device supporting coaxial antenna input from Schwarzbeck, Germany, which is authorized to be sold and quoted by EUTTEST Shenzhen. This coupling decoupling network is specified in Appendix B 3.2 of the CISPR 16-1-3 standard.This device can be used to check the decoupling coefficient DR of the MDS 21C power absorber clamp.. The ground connector of the isolated BNC jack on the EuT side of the device is connected to the inner conductor of the interference source connector via a 100 Ω resistor. You can connect a signal generator to the interference source connector to apply an interference voltage, or you can connect an EMC measurement receiver to measure the signals emitted by the EuT.
