Electro-optical

Performance

•

General conditions:

Temp = 25°C (package temperature)

Light source: 2854 K with 2 mm BG38 filter (unless specified) + F/3.5 optical

aperture.

30 images per second mode (Ti = 33 ms) under typical operating conditions

•

Readout mode: 2 outputs

•

Values exclude dummy elements and blemishes

Notes:

1. Pixel saturation (full well) as a function of vertical transfer frequency (see Figure 14 on page 15) and antiblooming adjust-

ment (see Figure 15 on page 15).

2. After substraction of dark signal slope due to memory readout time.

3. First line level referenced from inactive prescan elements (12 samples).

4. Last line level referenced from inactive prescan elements (12 samples).

5. Measured with Correlated Double Sampling (CDS) including 160 µV readout noise and dark current noise in general test

conditions.

6. Saturation to RMS noise in darkness ratio.

7. At Nyquist frequency.

8. VSAT/2 measurement and 417 kHz vertical transfer frequency.

9. VSAT/2 measurement and 10 MHz horizontal transfer frequency.
