Electro-Interference Test Report on Power Supply Group, Figure A 1379

摘要

The Test Item was tested as Class HI equipment as defined in reference 1.3. Broadband, interference tests, both radiated and" conducted, were performed. Susceptibility tests were not required for this Test Item.nRadiated, broadband, transient interference, generated by opening and closing relay K1 exceeded the limits of reference 1.3 at all frequencies. Radiated, broadband, steady-state interference exceeded the limits at only one frequency, 1.3 Megacycles.nConducted, broadband, transient interference, generated by opening and closing relay K1 and measured on the ac and do power leads, exceeded the limits of reference 1.3 at many frequencies. Conducted, broadband, steady-state interference measured on the ac power leads exceeded the limits at several frequencies.
