Notes:
1. Pixel saturation (full well) as a function of vertical transfer frequency (see Figure 14) and antiblooming adjustment (see Fig-
ure 15).
2. After subtraction of dark signal slope due to memory readout time.
3. First line level referenced from inactive prescan elements (17 samples).
4. Last line level referenced from inactive prescan elements(17 samples).
5. Measured with Correlated Double Sampling (CDS) including 160 µV readout noise and dark current noise in the general test
conditions.
6. Saturation to RMS noise in darkness ratio.
7. At Nyquist frequency.
8. VSAT/2 measurement and 1.25 MHz vertical transfer frequency.
9. VSAT/2 measurement and 20 MHz horizontal transfer frequency.
