Here's some test patterns I made on my Quantum Data pattern generator. I converted them to .PNG format and double checked the windows against CalMAN RGB tripletts. They are all generated with video levels, with black at 16. If playing on a media server, RGB PC levels should be used. Also, the .PNG format makes them ideal for use with the VideoForge pattern generator, which is how I use them now.
First are some normal (non APL) very small windows. They are approximately 4% size.

Second are the same window sizes but in APL flavor loosely based on inspiration I got from the AVS 709 APL windows- thanks Alluringreality! They are in between the AVS 709 large and small APL size.

The gamma pattern is especially useful for checking 10 point white balance control mistracking. Example: with settings at default, take the blue (or whatever color you want to check) control at, say, 80% and turn it all the way down. Then display the gamma pattern. Run the contrast control up and down and observe if the discolored square remains at 80% or if it moves up to, say, 90%.
The color pattern can be used with the color filters for a quick meterless check of color decoder nonlinearities, as it has matching levels at 50, 75, and 100%. If red, for example, blends in with the gray surround at 50% (bottom horizontal row) and 75% (middle row) but is darker than the surround at 100% (top row), you know your color decoding is nonlinear and you can take steps to correct it (lower contrast, change panel brightness, etc).
The aspect pattern is handy for adjusting anamorphic lenses or lens memories on front PJs.NEW!AVCHD ISO image thanks to Vega509
