Abstract: An Electronic Isolation Chamber With Unimpeded Hand Entry is disclosed. The somewhat “open” appearance of the Electromagnetic Isolation Chamber goes contrary to teachings in the art of RF shielding and enclosures. A sleeve through an aperture in the chamber is worn by an operator, and with the placement of an operator's arm there through, the electromagnetic shielding is completed and the volume contained within the chamber is electromagnetically isolated from the environment exterior to the chamber. This novel arrangement allows an operator to work with bare hands, thus providing more tactile interaction with a device under test and also reducing the tendency for shorting that is present when wearing conductive gloves. A shielded window and an interior light may be included to facilitate viewing of a device within the chamber during operation of the device.
