14. Apply a 5-step staircase wave (as in the figure below) to Y-IN, and measure the luminance level (Y) and the sync
level (S) in the Y-OUT output.
S [mV]
LS =
× 100 [%]
Y [mV]
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.
Measure the noise with a noise meter with a 200-kHz low-pass filter, a 5-MHz low-pass filter, and a 4.43-MHz trap
filter.
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,
and let V2 be the Y-OUT output when SW3 is set to the b position.
V2 [mVp-p] — V1 [mVp-p]
ZOY =
× 500 []
V1 [mVp-p]
18. Measure the delay time in the Y-OUT output with respect to the input to Y-IN.
