STE2300 RF Shielded Test Enclosure

As isolated RF testing evolved into more applications, so did the size, design, and style of the enclosures. The STE2300 was designed as the little brother and smallest STE available for small wireless devices. As wireless LAN devices became smaller, it made sense to step-up the STE2300 to a slightly larger design that also utilized our standard universal I/O interface panel. This not only allowed the testing of larger devices, but gave the user the same I/O capacity of our largest enclosures.

Description

The STE2300 RF Shielded Test Enclosure is a compact and reliable RF shielding solution designed to support accurate and repeatable wireless testing in both laboratory and production environments. Engineered to provide consistent isolation from external RF interference, the STE2300 helps ensure dependable measurement results during device development, validation, and manufacturing.

Designed with ease of use in mind, the STE2300 features a practical enclosure layout that allows quick access to the Device Under Test (DUT). This makes it well suited for high-cycle testing where efficiency and repeatability are critical. Its durable construction supports daily operation while maintaining stable shielding performance over time.

The STE2300 RF Shielded Test Enclosure integrates easily with RF connectors, filtered I/O interfaces, and test fixtures to match specific testing requirements. This flexibility allows engineers to adapt the enclosure to a wide range of wireless devices, including IoT products, consumer electronics, and embedded modules.

By creating a controlled RF environment, the STE2300 helps reduce measurement variability and minimizes the risk of false failures. As a result, test teams can improve throughput while maintaining confidence in test accuracy. The enclosure is an ideal choice for organizations that need dependable RF shielding in a compact, production-friendly form factor.

Specifications

RF Shield Box STE2300 Specifications

Size wise, we increased the width to 9 inches, the height to 5 inches and the depth to 12 inches. This together with the extended I/O capacity gives the user all the benefits of the larger enclosures while keeping closely within size of his DUTs. And that’s a cost savings. In addition to the standard universal I/O panel we also designed in the option for cross ventilation to cool the DUT. For the first time these advanced features became available in a small hand-held test chamber!
