RE: Exercising test sample during emissions testing

The H pattern was to increase monitor emissions; turning the electron beam on and off periodically was a surefire way to raise emissions. I've seen a monitor with H's make a computer _beside the EUT_ test fail conducted emissions even though turned OFF. Nowadays a Windows (etc) halftone pattern

From: Ken Javor Sent: Wednesday, June 06, 2007 9:42 PM A long time ago, when DOS was the PC operating system, I seem to recall that a PC undergoing emissions testing was supposed to continually write the character H to the CRT display. What is the requirement today under CISPR or other
