ST-A1332 RF chamber

Shielded chambers isolate internal and external electromagnetic waves via metal shielding enclosures. They are mainly categorized into four types: EMC testing, 

RF communication testing, precision instrument protection, and confidential security shielding. They perfectly match the application scenarios of your testing acoustic shielding 

equipment industry.

RF Performance Testing Applications

1. Calibration of wireless product specifications: Testing for Wi-Fi, Bluetooth, 5G, NFC, RF connectors, antenna transmit/receive power and receiving sensitivity;

2. Isolation of external signal interference: Block signals from outdoor base stations, radio stations and industrial inverters to avoid distortion of test data and guarantee measurement accuracy;

3. Passive component testing: Insertion loss and VSWR testing of RF cables, adapters, shielding boxes and couplers.

The ST-A1332 Mini Anechoic Shielded Chamber delivers premium testing environments for RF tests in R&D departments and laboratories.

Technical Compliance Standard

Test standard basis: GB/T 12190-2006 Measurement Method for Shielding Effectiveness of Electromagnetic Shielded Enclosures

Calculation of Shielding Effectiveness

Shielding effectiveness is abbreviated as SE, with the unit decibel (dB).It can be expressed by power ratio:

Where:P₁ = Incident power, the power measured at the observation point without shielding;P₂ = Transmitted power penetrating the shield, the power measured at the identical observation point after installing the shield.
