Abstract

An analysis of the electromagnetic emissions of an IBM Model 32772 visual display unit showed no hazardous levels in any portion of the spectrum. The actual level of emission was measured throughout the spectrum from low frequency radio waves through x-radiation, extending from 10 KHz through 10 GHz, then 0.2 to 10 μm, and from 5 to over 40 keV. In many parts of the spectrum, the level of emission was below the sensitivity of available instrumentation. In the radio frequency range, including the microwave region, measurements were also made on black and white and color television sets for the purpose of comparison.
