NOTES:
2. Dynamic range is –20 times the logarithm of the mean-noise signal divided by the saturation-output signal.
3. For this test, the antiblooming gate must be biased at the intermediate level.
4. 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.
5. Signal-response delay time is the time between the falling edge of the SRG clock pulse and the output-signal valid state.
6. 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):
Exposure (2)
Exposure (1)
Output signal (2)
Output signal (1)
7. ADB rejection ratio is –20 times the logarithm of the ac amplitude at the output divided by the ac amplitude at ADB.
8. SRGn rejection ratio is –20 times the logarithm of the ac amplitude at the output divided by the ac amplitude at SRGn.
9. ABG rejection ratio is –20 times the logarithm of the ac amplitude at the output divided by the ac amplitude at ABG.
