Quantum Data 801GC, 801GF, 801GX manual Built-In Images

Test:	Color Video Performance
Purpose:	This general purpose pattern can be used to check
	the video handling capabilities of most parts of a
	television system.
Method:	When viewed on a TV screen, all of the upper color
	bars should be correct and in the order shown. The
	hue and intensity of each bar should be uniform
	over the entire bar.
	The image can be used with a TV waveform analyzer
	to check the performance of a video system. The
	upper color bars, as they would appear on a waveform
	analyzer, are shown on a previous page.
Test:	Color Decoder Performance
Purpose:	The image can used with a TV vectorscope to check
	for proper operation of a video color decoder.
	Vectorscope signatures of the upper and lower
	portions of the image using NTSC encoding can be
	found on the previous pages.
Method:	The vectorscope signature for the color bars should
	hit the target test point for each color on the
	vectorscope’s graticule. If you are using PAL encoded
	video, the signature will be similar to the one shown
	for the TVBar_75 test image on an earlier page.
	The three “legs” of the vectorscope signature for
	the -I and Q color difference signals should match
	the Burst, -I and Q reference lines on the vectorscope’s
	graticule.
