About:

ZN3752 Type A coupling network is a coaxial coupling and decoupling network. The production design of this product complies with the national standard of the People's Republic of China, GB/T6113-102, CISPR16-1-2.

Type A coupling network is mainly used for the detection of the decoupling factor (DR) of the power absorbing clamp and the calibration measurement of the original calibration method of the absorbing clamp. (See Figure 4-5)

The purpose of this coupling network is to provide a degree of immunity to the equipment under test (EUT) from environmental high-frequency disturbances, creating a repeatable environment for the measurement test setup.

The ZN3752 Type A coupling network can also be used to check the immunity of RF receivers. where sheath current is injected into the coaxial input. (Chapter 6 of GB/T6113.102CISPR 16-1-2 describes this test procedure)
