5. Measure the C-OUT output when a 200-mVp-p sine wave is input to C-IN1 and C-IN2, and when a 500-mVp-p sine
6. Measure the 3fsc (13.3 MHz) and fsc (4.43 MHz) components in the C-OUT output with no input signal.
7. Measure the noise in the C-OUT output with no input signal.
8. Input a 350-mVp-p sine wave to C-IN1 and C-IN2. Let V1 be the C-OUT output when SW3 is set to the ‘a’ position,
9. The delay time in the C-OUT output with respect to the C-IN1 input. This is the CCD 1-bit delay.
10. The pin output voltage (clamp voltage) with no input signal.
11. Measure the Y-OUT output with a 200-kHz 400-mVp-p sine wave input to Y-IN.
12. Measure the Y-OUT output when a 200-kHz 200-mVp-p sine wave is input to Y-IN, and when a 3.3-MHz
13. Apply a 5-step staircase wave (as in the figure below) to Y-IN, and measure the differential gain and differential
wave is input, and calculate the gain difference as follows:

Measure the noise with a noise meter with a 200-kHz high-pass filter and a 5-MHz low-pass filter.
and let V2 be the C-OUT output when SW3 is set to the 'b' position.
