The anechoic chamber is mainly composed of shielding chamber and microwave absorbing material. The shielding room is composed of shielding shell, shielding door, ventilation waveguide window and various power filters. According to user requirements, the shielding shell can be welded or assembled. The absorbing material is composed of a single-layer ferrite sheet with a working frequency range of 30MHz ~ 1000MHz and a conical carbon sponge absorbing material. The conical carbon sponge absorbing material is made of polyurethane foam infiltrated in carbon glue solution and has good flame retardant characteristics.

The power frequency magnetic field is generated by the power frequency current in the conductor, or a very small amount of it is generated by other accessories (such as the leakage flux of the transformer). Power frequency magnetic field may affect the reliable operation of equipment and system. The power frequency magnetic field generator is used to evaluate the performance of household, commercial and industrial electrical and electronic equipment in power frequency (continuous and short-time) magnetic field. The products meet the requirements of new standards such as iec61000-4-8 and gb/t17626.8.
Voltage dips/sags, short interruptions are caused by failures of the power grid and power facilities or sudden large changes in loads. In some cases, there will be two or more consecutive dips or interruptions. Voltage changes are caused by continuous changes in the loads connected to the grid. If the EUT cannot respond in time to changes in the power supply voltage, it may cause malfunctions. Voltage dips generators are used to evaluate the performance of electrical and electronic equipment when subjected to voltage dips/sags, short interruptions, and voltage changes. Products fully meet the requirements of standards IEC/EN 61000-4-11 and GB/T17626.11.
In the circuit, such as from the switching transient process (cutting off inductive loads, bouncing relay contacts, etc.), it will usually interfere with other electrical and electronic equipment in the same circuit. This kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. Clusters of narrow pulses can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. The burst generator determines a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient bursts. The products meet the requirements of new standards such as iec61000-4-4, en60100-4-4 and gb/t17626.4.
