NOTES:

2. Dynamic range is – 20 times the logarithm of the mean noise signal divided by the saturation output signal.

3. Charge transfer efficiency is one minus the charge loss per transfer in the output register (1046 transfers). The test is performed

in the dark using an electrical input signal.

4. Signal-response delay time is the time between the falling edge of the SRG clock pulse and the output signal valid state.

5. Gamma (

γ) is the value of the exponent in the equation below for two points on the linear portion of the transfer function curve (this

value represents points near saturation):

6. ADB rejection ratio is – 20 times the logarithm of the ac amplitude on OUTn divided by the ac amplitude on ADB.

7. SRGn rejection ratio is – 20 times the logarithm of the ac amplitude on OUTn divided by the ac amplitude on SRGn.

8. ABGn rejection ratio is – 20 times the logarithm of the ac amplitude on OUTn divided by the ac amplitude on ABGn.
