STE2950 RF Shielded Test Enclosure

The Top Load version of the STE2900! Also designed for individual bench top or dual rack mount installations, the STE2950 makes it simple to load and unload the device under test with its top load access door. The dual rack mount configuration allows multiple installations for dense pack environment testing. The dual rack version STE2952 includes a custom rack slide allowing the entire enclosure to be pulled out for top access.

To allow proper cooling of the DUT each STE2950 includes a built-in passive 60mm vent option. Optional forced-air fans can be ordered for additional cooling. Like other Ramsey enclosures, our universal I/O panel on the back wall is included and ready for your custom configuration to meet your application. Heavy duty, rugged .090 and .125 aluminum is used throughout and our double lip, high performance gaskets are used at all joint locations assuring a reliable RF tight closure. RF absorbent foam lines the interior to provide a typical RF attenuation of -90dB @ 3GHz. If you are looking for an off-the-shelf RF enclosure system providing enough room to test any size wireless device, from Cellular phones to MIMO access points, you can count on the STE2950 to keep the device isolated.

The STE2952 includes dual STE2950’s mounted on a custom 19″ rack mount slide ready for installation into your rack. Access to the DUT is easy by the pull-out slide giving you full access to the hinged top mounted shielded doors. If you don’t have available rack space or need high density testing in the field, our STE2952C has dual STE2950’s pre-mounted and configured in a custom shock mounted road case. Great for field service trips.
