Space-saving RF Wireless Test Chamber for Consumer and Automotive Applications

Turnkey test and measurement solutions provider, Alfamation, has released an RF wireless test chamber that is three times smaller than alternative products on the market. The WSC-6 offers comparable performance to competitors' solutions, providing a typical shielding effectiveness of over 90 dB. However, it is one third the size of most other solutions, measuring 230 x 280 x 130 mm. This exceptionally compact size and the fact that WSC-6 is stackable, creates new space on the factory floor. Depending on the product size and application, the chamber can typically host more than one device under test (DUT).

The WSC-6 can be used to test any wireless device transmitting in the 500 MHz to 6 GHz range. This includes any wireless device for consumer and automotive applications, including Wi-Fi, Bluetooth, LTE, 5G smartphone, and V2X (vehicle-to-everything) modules. It isolates the DUT from the external environment to enable accurate testing in high-volume production facilities, effectively shielded from any outside interference. It can internally reproduce the far field condition.

The test chamber is supplied in manual, semi-automatic and fully-automatic configurations. The manual mode is the simplest, where the operator opens and closes the door as required. In the semi-automatic mode, the chamber doors are locked and unlocked automatically, while fully-automatic means that the WSC-6 can be integrated into an automated production line with robotic loading and unloading of DUTs.

The chamber is available both as a standard product as well as in customized configurations for specific customer needs, for example various sizes and shapes. Alfamation can also fully integrate and supply the test chamber as part of a customized manufacturing test cell. It is very heavy-duty, constructed on a solid cast aluminium base, enabling pneumatically-assisted loading and unloading. It includes status LEDs and provides all the necessary space for testing-related electronics.
