Ramsey Electronics began in 1997 and quickly earned its claim to fame with the manufacture of portable, handheld radiofrequency (RF) shielding. Until Ramsey created this innovative piece of test equipment, technicians had to work in large, shielded screen rooms. The patented benchtop RF Shielded Test Enclosure revolutionized the way technicians could conduct RF testing, creating a worldwide switch to portable RF shielding. Since then, Ramsey has continued to be on the cutting edge of RF test equipment, producing global digital forensics solutions and devices at very affordable costs.
