Conditions

Input SIG6 (VL = 0mV) to (A) and SIG3 (0dB, 3.58MHz)

to (B) and change the chroma phase. Assume the

maximum amplitude at TP39 as VR, the maximum

amplitude at TP41 as VG, and the maximum amplitude

at TP43 as VB, and calculate VRBN = VR/VB and VGBN

= VG/VB. V60 = 3.5V

Input SIG6 (VL = 0mV) to (A) and SIG3 (0dB, 3.58MHz)

to (B) and change the chroma phase. Assume the phase

at which the maximum amplitude at TP39, TP41 and

TP43 as θR, θG and θB, respectively, and calculate

θRBN = θR – θB and θGBN = θG – θB.

V60 = 3.5V

Input SIG6 (VL = 0mV) to (A) and SIG3 (0 dB, 4.43MHz)

to (B) and change the chroma phase. Assume the

maximum amplitude at TP39 as VR, the maximum

amplitude at TP41 as VG, and the maximum amplitude

at TP43 as VB, and calculate VRBP = VR/VB and VGBP

= VG/VB. V60 = 3.5V, SW7 = C

Input SIG6 (VL = 0mV) to (A) and SIG3 (0 dB, 4.43MHz)

at which the maximum amplitude at TP39, TP41 and

TP43 as θR, θG and θB, respectively, and calculate

θRBP = θR – θB and θGBP = θG – θB.

V60 = 3.5 V, SW7 = C
