13. Input a five-level step waveform (see the figure below) to Y-IN and measure the differential gain and differential
phase in the Y-OUT output with a vector scope.
14. Input a five-level step waveform (see the figure below) to Y-IN and measure the luminance level (Y) and the sync
level (S) in the Y-OUT output.
LS =
× 100 [%]
15. Measure the 3 fsc (13.3 MHz) and fsc (4.43 MHz) components in the Y-OUT output with no input.
16. Measure the noise in the Y-OUT output with no input.
Measure the noise with a noise meter set up with a 200 kHz high-pass filter, a 5 MHz low-pass filter, and a 4.43 MHz
trap filter.
17. Let V1 be the Y-OUT output with a 200 kHz 400 mVp-p sine wave input and SW3 set to c, and let V2 be the C-OUT
output with SW3 set to b.
ZOY =
× 500 []
18. The Y-OUT delay time with respect to Y-IN
V2 [mVp-p] – V1 [mVp-p]
V1 [mVp-p]
S [mV]
Y [mV]
