What factors affect the anechoic chamber?
The factors that affect its performance index mainly include darkroom parameters, antenna measurement errors and other errors.The electrical performance of microwave anechoic chamber is mainly characterized by the characteristics of static zone. The characteristics of the static zone are described b

What are the categories of radio signals?
Anechoic chamber generally, for radiation test, the test site is divided into three types: full anechoic chamber, semi anechoic chamber and open field. The radiation tests conducted in these three test sites can generally be considered to conform to the propagation law of electromagnetic waves in fr

Type of PSD
Shielded machine room is a place for shielding against radio wave interference. The parameter for measuring the permeability of materials is permeability. The higher the permeability, the higher the permeability, and the better the shielding effect. The doors and windows of the shielding room also h

The role of weak current engineering shielding machine room
The basic principle of weak current engineering shielding machine room comes from Faraday cage design. Without shielding, our electronic equipment will be affected by interference sources, resulting in equipment failure or abnormal operation, and even damage in serious cases. Another phenomenon is t

Analysis of influencing factors of shielding machine room effect
When the frequency of the factors affecting the shielding data effect of the electromagnetic shielding machine room is high, the absorption loss is the main shielding mechanism, which has little to do with whether the radiation source is an electric field or a magnetic field. When the frequency is l

Precautions during construction of shielded machine room
Construction precautions:1. every seam and discontinuity between the bottom plate and the casing shall be overlapped as well as possible. The degree of overlap plays a decisive role in the shielding effectiveness of the shell; When the requirements for shielding, ventilation and strength are high bu

Grounding mode of shielding machine room
Grounding is a wire connection set to discharge charge or provide a reference potential. There are two purposes of grounding. One is to protect people and equipment from lightning, electric leakage, static electricity and other hazards. This kind of ground wire is called protective ground wire, whic
