In 1997 Ramsey Electronics® took technicians out of large  expensive shielded screen rooms and put RF shielding into the palms of  their hands.  Our patented portable benchtop RF Shielded Test Enclosure  was a revolution in RF testing, providing unprecedented visual and  hands-on access to equipment in a tightly controlled RF-free test  environment.  With tens of thousands of Ramsey Electronics®  RF Shielded Test Enclosures now in service worldwide, our STE designs  and technologies have become the industry standard for efficient and  cost effective RF isolated device testing.
