NOTES:

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

4. For this test, the antiblooming gate must be biased at the intermediate level.

5. Charge transfer efficiency is one minus the charge loss per transfer in the output register. The test is performed in the dark using

an electrical input signal.

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

7. 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):

8. ADB rejection ratio is – 20 times the logarithm of the ac amplitude at the OUT divided by the ac amplitude at ADB.

9. SRG rejection ratio is – 20 times the logarithm of the ac amplitude at the OUT divided by the ac amplitude at SRG.
