4. Measure the comb depth from the C-OUT output with a 350 mVp-p sine wave signal of frequency fa input to C-IN1

and C-IN2 and with a frequency of fb input.

5. Measure the C-OUT output with a 200 mVp-p sine wave signal input to C-IN1 and C-IN2 and with 500 mVp-p sine

wave signal input and calculate the difference in the gains.

6. Measure the 4 fsc (14.3 MHz) and fsc (3.58 MHz) components in the C-OUT output with no input.

7. Measure the noise in the C-OUT output with no input.

Measure the noise with a noise meter set up with a 200 kHz high-pass filter and a 5 MHz low-pass filter.

8. Let V1 be the C-OUT output with a 350 mVp-p sine wave input to C-IN1 and C-IN2 and SW3 set to a, and let V2 be

the C-OUT output with SW3 set to b.

9. The C-OUT output delay time with respect to inputs to C-IN1. (the CCD 2.5 bit delay)

10. Y-OUT voltage (clamp voltage) with no signal input.

11. Measure the Y-OUT output with a 200 kHz 400 mVp-p sine wave input to Y-IN.
