I've added an additional section about the noise issue after doing some additional measurements: https://tomverbeure.github.io/2025/05/04/TDS684B-CCD-Memory.html#a-closer-look-at-the-noise-issue https://tomverbeure.github.io/2025/05/04/TDS684B-CCD-Memory..... It's a repeating pattern of ~195 samples so it's easy to figure out this pattern during calibration and subtract it from the values measured by the ADC. In addition to that, there is also some interleaving going on.
