CISPR 32 requires the color bars with a moving element.  What that moving 
element is isn't nailed down in the standard.  The reason for the moving 
element is that we (CISPR SC I) are trying to harmonize CISPR 32 (emissions) 
and CISPR 35 (immunity) to the maximum extent possible.  You need a moving 
element for immunity so you know that the image is no longer being updated if 
you fail an immunity test.  A static image would not give you that information.

Hi Tom,
I just found your posting of the ITU-R BT.1729 colour bar test pattern.  This 
is great!

Does this fully implement the ITU-R BT.1729 colour bar test pattern?
 ** BOUNCING BALL:  I couldn't find anything in the standard that mentions a 
bouncing ball, but I like the feature and one could argue that this might catch 
some problems missed without it.
 ** ZONE 12 MOVING BAR:  Page 6 of the standard states that "Zone 12 contains a 
bar which moves horizontally from
left to right and then starts again from the left. This is used for checking 
audio-video synchronization and to establish that the channel is active. The 
bar travels horizontally across its zone in 1 s. The audio sync signal is given 
when the bar passes the centreline."  There is more description to the zone 12 
in the standard, but the above quote is sufficient to say that I don't see 
anything moving in zone 12 of your application.

Do you have plans to fix the zone 12?

I am definitely looking for something I can use to test monitors for CISPR32 
using the ITU-R BT.1729 colour bar test pattern.

For all, the ITU-R BT.1729 standard is available online for free at:
http://www.itu.int/dms_pubrec/itu-r/rec/bt/R-REC-BT.1729-0-200504-I!!PDF-E.pdf

Thanks.

Hello,



We used to use scrolling-Hs test pattern for CISPR 22 and ANSI C63.4,

but CISPR 32 requires ITU-R BT.1729 colour bar with small moving element

for computer displays and similar devices.



Now, I made web pages which will display the test pattern on web browsers.
