The Schaffner CDN126 Capacitive Coupling Clamp enables burst pulses to be coupled into an item of equipment under test (EUT) without an electrical connection to its inputs or outputs, the screened sheathing of associated cables or any other part of the EUT.
The coupling clamp is necessary for acceptance tests on 110 and communications ports. Mains inputs can also be tested, however, in cases where the direct coupling networks cannot be used.
The CDN 126 consists of a 1m long, metallic clamp designed to accommodate the cable to be tested. The return path is provided by a reference panel placed under the clamp. The configuration conforms with IEC 1000-4-4 (corresponding to IEC 801-4).
