Radiation Test;Radiated Emission（RE) & Radiated Spurious Emission（RSE）

Radiation Test Basic introduction
The test site can be divided into isolation rooms (including TEM / GTEM Cell and other EMC test rooms), anechoic chambers, and open area test sites (OATS).
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 small (such as the general electromagnetic compatibility standards and specifications require at least 6dB below the allowable limit value).

Anechoic chamber (semi-anechoic chamber, full-anechoic chamber)
First, the 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).
Minimum practical size anechoic chamber:
The size is about 7m * 3m * 3m, which is mainly used for RF immunity, emission estimation and free space emission testing. Suitable frequency is 26MHz-1GHz, suitable for small and medium enterprises to do internal testing.
3m anechoic chamber:
The size is about 9m * 6m * 6m. It is used for products with radio frequency immunity and emission test size below 2m. It is an experimental field widely used in the world instead of the open field.
10m method anechoic chamber:
The size is about 19m * 12m * 9m. It is used for RF immunity and emission testing, and is suitable for larger products. It is very expensive and can test other special equipment such as cars.

Second, the full anechoic chamber
Used to simulate the propagation environment of free space. It is mainly used for parameter measurement of microwave antenna system.
RS radiation immunity interference
Using a 3m full-anechoic chamber test site that can fully meet the latest standards, the test frequency is: 80MHz-6GHz; EFIELD STRENGTH can reach: 3V / m; 10V / m; 20V / m; field uniformity fully meets IEC61000-4- 3 requirements. The R & S TS9980 radio and television audio immunity test system can meet the requirements of different systems in different countries, such as: DVB-T, -H, -C, -S1, -S2, ATSC, DAB, etc.

About Us

Shenzhen LCS Compliance Testing Laboratory Ltd., abbr. for LCS, was founded in 2004 in Shenzhen, LCS is now growing into an independent comprehensive third-party institution which focuses on test & certification. Profound technical background and diligent working attitude decided LCS with an outstanding high starting point from the outset，pioneering spirit and consciousness of keeping pace with the times which predestined the thoroughly tempered course of LCS.

Our Labs

LCS Founding Members have engineering background and had gradually built up Safety Lab, EMC Lab, RF Lab, SAR & HAC Lab, Reliability Lab, Lighting Electrical Lab, LED Lighting Performance Lab, Energy Efficiency Lab, Electronic Cigarette Testing Lab, Chemistry Lab, BQTF, Environmental and Occupational Evaluation Lab, Battery Lab, Toy Lab, Textile Lab, Food and Food Grade Material Lab. The establishment of our comprehensive labs ensure our test and certification scope covers almost all fields, such as Reliability and Safety test, EMC test, Chemical Hazardous Substances test, Material Analysis, Food Contact Material test, Bluetooth Test & Certification, Environment and Occupational Health, Performance test of spare parts of Automobile and so on.

Authorization

Moreover, LCS won many authorized qualifications both domestic and overseas. LCS is recognized as IEC/ISO17025 laboratories accepted by CNAS and NVLAP, accredited by CPSC, CMA, accredited for CQC, ISTA, CBTL, SASO, SABS. Meanwhile LCS become laboratory authorized by TUV, BQTF issued by the SIG. LCS had also signed cooperation agreements with FCC, ISED, ETL, CEC, UL, E-Mark, CETECOM, KTC, SAA Approval and many other authoritative institutions, hence we can provide our clients with efficient and professional service for product test and certification.

Experience

Our RF experience ranges from WLAN (802.11b/g/n/a/ac), Wi-Fi 6E, Bluetooth (802.15.1), ZigBee (802.15.4), Z-Wave, UWB (802.15.3), WiMAX (802.16), SRD, DECT, RFID, NFC, GSM, WCDMA (+HSDPA/HSUPA), LTE, 5G (NR/VoNR/eMTC/eMBB/URLLC),UHF/VHF, WHDI, AM, FM, DAB, DVB, GPS, GNSS, COMPASS, GLONASS and more. The products we are mostly working with are basestations, client adapters, laptops, cordless phones, baby monitors, cellulars, radars, sensors, scanners, receivers, immobilizers, remote controls, etc. Modern products incorporate not often one, but a variety of co-existing technologies.
