1. Set unicolor to maximum (1111111), SRT-GAIN to minimum (00000), color to center (1000000), and color
limiter level to 2 Vp (1). Input SWEEP signal to TPA so that #68 amplitude is 20 mVp-p. Set SW67 to A, and
input signal as shown in the figure below (#67 amplitude is 0.2 Vp-p) to TP67.
2. Set picture sharpness to center (1000000), Y detail control to center (1000), and monitor #14 with a spectrum
analyzer.
3. When CDE is at minimum (00), set low frequency area to 0dB, and determine peak level G
CDEMIN
.
4. When CDE is at maximum (11), set low frequency area to 0dB, and determine peak level G
CDEMAX
