14. Apply a 5-step staircase wave (as in the figure below) to Y-IN, and measure the luminance level (Y) and the sync
15. Measure the 3fsc (13.3 MHz) and fsc (4.43 MHz) components in the Y-OUT output with no input signal.
16. Measure the noise in the Y-OUT output with no input signal.
17. Input a 200-kHz, 400-mVp-p sine wave to Y-IN1. Let V1 be the V-OUT output when SW3 is set to the ‘c’ position,
18. Measure the delay time in the Y-OUT output with respect to the input to Y-IN.
