ON (1) Set picture mute to off (P-MODE: Normal1 (000)), UNI-COLOR to maximum (1111111), SHR-TRACKING to
SRT-GAIN minimum (11), COLOR to center (1000000), color limiter level (CLT) to 2 Vp (1) and C-SRT-FREQ
to 4.5 M (10). Input SWEEP signal to TPA and set pin 3 amplitude to 20 mV_P-P. Set SW4 to A. Input signal
(pin 4 amplitude: 0.2 V_P-P) to TP4 as shown in the figure below.
(2) Set PICTURE-SHARPNESS to center (1000000) and Y DETAIL CONTROL to center (10000), and monitor
pin 41 using a spectrum analyzer.
(3) Set low-frequency area to 0dB when CDE is set to minimum (00) and measure peak level G_CDEMIN.
(4) Set low-frequency area to 0dB when CDE is set to maximum (11) and measure peak level G_CDEMAX.
(5) Calculate using the following formula.
G_CDE00 = G_CDEMAX00 − G_CDEMIN00
(6) Set APACON PEAK f₀ to 15 M (00), 8.8 M (01), 7.5 M (10) and 5 M (11), and measure peak levels G_CDE00,
G_CDE01, G_CDE10 and G_CDE11.
