No, as I wrote "These colorbars (test patterns) were derived from ITU-R BT.1729, but they are not accurate." in the BUGS section of the page. Especially, frequency and waveform of color sweeps are incorrect. > left to right and then starts again from the left.

No at least at this time, and I thought this Zone 12 is not important for CISPR 32/35, as we usually use 1 kHz monotone audio signal and will not check audio-video sync. However, I would appreciate if someone can help improve this test program, expecially those test patterns.
