Currently I have a Colour bar being generated by a Sony HXCU-D70 fed into a Tektronics WFM7120 then looped into a Blackmagic Decklink 3D Extreme. I am using the Decklink SDK to develop applications. I am using driver version 22.214.171.124 and SDK version 9.5
I have the WFM setup to look at the raw data of the image and have printed to screen data for the same pixel.
In short my WFM shows no change in the data yet the data coming back from the Decklink card appears to be varying.
I am writing an application to analyse the data on screen and this variation is showing up in my readings.
