INTEGRATOR’S NOTE
EMC emission testing of high-speed video was performed on this Desktop Board using scrolling
H’s displayed on the video monitor in accordance with ANSI C63.4-2000 documentation. The
scrolling H’s are displayed using the following font sizes:
• For video resolutions greater than 1600 x 1200 (including 2048 x 1536 and 1920 x 1440),
a font size of 200% is used.
• For a 1600 x 1200 video resolution, a 150% font size is used.

All available resolutions are tested using the highest available color depth and monitor refresh
rate.
