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

12. Measure the Y-OUT output when a 200-kHz 200-mVp-p sine wave is input to Y-IN, and when a 3.5-MHz
200-mVp-p sine wave is input.
The Y-OUT output for a 3.5-MHz input [mVp-p]

FY
= 20log ————————————————————— [dB]
The Y-OUT output for a 200-kHz input [mVp-p]
Here, adjust Vbias so that the clamp level is +250 mV.
13. Apply a 5-step staircase wave (as in the figure below) to Y-IN, and measure the differential gain and differential
phase in the Y-OUT output using a vector scope.
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]
Y [mV]

15. Measure the 4fsc (14.3 MHz) and fsc (3.58 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 4.2-MHz low-pass filter, and a 3.58-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]

18. Measure the delay time in the Y-OUT output with respect to the input to Y-IN.
