basic introduction

The test site can be divided into isolation rooms (including TEM/GTEM Cell and other electromagnetic wave EMC test rooms), anechoic rooms, and open area test sites (OATS), etc.

Open field OATS

OATS is required to be flat and open, away from building landmarks, towers, wires, woods, underground cables and metal pipes, and the background of environmental electromagnetic interference should be very small (such as general electromagnetic compatibility standards and specifications require at least 6dB below the allowable limit value).

The early measurements of EMC radiation emission and sensitivity RS were all carried out in open fields. Since today's various electronic and electrical products have been widely used in people's ordinary lives, with the rapid development of electronic and electrical engineering, electromagnetic The noise environment is constantly deteriorating, and it is now difficult to find open sites that meet the standards for measurement.

Radio wave anechoic chamber (half radio wave anechoic chamber, full wave anechoic chamber)

1. Semi-anechoic chamber

It is used for EMC measurement and electromagnetic radiation sensitivity measurement. The main performance indicators are measured by normalized field attenuation (NSA) and test surface field uniformity (FU).

The smallest practical size radio wave darkroom:

The size is about 7m*3m*3m, which is mainly used for radio frequency immunity, emission prediction and free space emission testing. Suitable frequency is 26MHz-1GHz, suitable for small and medium-sized enterprises to do internal testing.

3m method anechoic chamber:

The size is about 9m*6m*6m, which is used for products with radio frequency immunity and emission test size less than 2m. It is a widely used experimental site in the world to replace open fields.

10m method darkroom:

The size is about 19m*12m*9m, which is used for radio frequency immunity and emission testing, and is suitable for larger products. The price is very expensive and can test other special equipment such as cars.

2. Full-wave anechoic chamber

Used to simulate the propagation environment of free space. Mainly used for parameter measurement of microwave antenna system.

RS radiation immunity interference

Adopt a 3-meter full-wave anechoic chamber test site that fully meets the latest standards, with a test frequency of 80MHz-6GHz; EFIELD STRENGTH up to: 3V/m; 10V/m; 20V/m; field strength uniformity fully meets IEC61000-4- 3 requirements. The R&S TS9980 radio and television audio anti-interference test system can meet the requirements of different standards in different countries, such as: DVB-T, -H, -C, -S1, -S2, ATSC, DAB, etc.
