Resistor Ladder		9/3/2023SNES 240P Test Suite**084156224300400472544616696768This is an example of the high voltage Ref 6.1 design. There appear to be two varriants of the Ref 6.1 Design. This version blows out highlights. Very strange behavior on the scope, at 0 IRE, with RGB at 0mV, as you move up the ladder to 100 IRE, Greens lower Peak value moves down, gradually all the way to -112mV this makes it hard to determine where to meassure combined mV readings, however results cross referenced with colorimeter.

The SNES gamma curve in these tests track a little brighter above 50 IRE, so values are expected to be a little higher, but at 50 and 60 IRE it couldn't quite stay close enough to 350 mV to earn a reference rating, and its seperation of colors at 100 IRE also kept it from earning the reference rating, but still a "Great" DAC.

This is a test of the same Moread I tested before but in the mister.ini I set hdmi_limited=2, which artificially changes the range for these AG6200's so blacks aren't crushed, but as a result, values higher then 50 IRE change as well, also any other device you use this DAC on will still have crushed blacks. Due to their being better DACs that work properly out of the box, I still strongly suggest people stay away from the AG6200.

Using the same HDFury 3 from previous testing, you can also see how it compares to the HDFury 3 with the 240P TestSuite from the SNES, I created a tab labeled "SNES S Curve" which helps demonstrate the "S Gamma Curve" the SNES has.

Analogizer R2 for Analogue PocketResistor Ladder?9/19/2024SNES 240P Test Suite***068134196262366430494556620682This is a bit of an odd one, it had about 8mV of seperation from G to R at 100IRE which isn't too bad in itself. But what is even more weird is the big change around 40-50 IRE, it should been a delta of 70mV, but on this device its 104mV! This is not good at all and requires a special rating as no other DAC or device has done this. Reference the images in the folder, https://drive.google.com/drive/folders/15qtZ_3RATxQB8f757LU-sYNjH8ToLbuq to see how this looks in the Gray Ramp image and Color Bars image. Note the drop off is because of the Pocket itself, not the Analogizer, as you can see in the pictures this occurs on the Pockets screen itself as well as the TV, so its something wrong with either the core on the Pocket or the Pocket device itself. I tested the Genesis and PCE 240P test suite as well and noticed similar issues.
