CISPR-25 semi anechoic chamber

The main purpose of CISPR-25 semi-anechoic chamber is to perform measurements of radiated emission or immunity specialized for vehicle on board equipment testing. The combination of the pan-type 2mm galvanized panel system, parallel closing RF shielded doors and polystyrene hybrid absorbers on the walls and ceiling  eliminates unnecessary RF reflection and provides a high performance controlled electromagnetic environment that complies with international immunity and emission test standards, especially for automotive test standards, such as CISPR-25.

Features of a CISPR-25 semi anechoic chamber:
Noise floor level as per CISPR-25 requirements
Grounded EUT test table as per CISPR-25 design guide lines
Non-interference LED lights to meet the stringent requirements of CISPR-25 noise floor level

Acceptance standards for a CISPR-25 semi anechoic chamber:

CISPR 12/en55012
ISO-11451
ISO-11452
SAE J551

Product standards for a CISPR-25 semi anechoic chamber:

      Typical performance of a CISPR-25 semi anechoic chamber:

The minimum return loss of absorbers between 70MHz and 6GHz is 6dB. The model long wire antenna method (LWM) long line method is adopted to meet the new CISPR25 standard. The error between the actual test points of darkroom meeting more than 90% and the theoretical value of the model is not greater than ±6.0dB.

In addition to the typical specifications of CISPR-25 semi anechoic chamber, RFT can also customize the anechoic chamber configuration for customers’ requirements.
