Note 5. With normal reference input signal voltage, adjust chroma input signal voltage to 1.2Vp−p.
Note 6. With normal reference input signal voltage, adjust chroma input signal voltage until the B output voltage = 5Vp−p. The chroma input voltage at this point should be equal or lessthan
700mVp−p.
Note 7. With normal reference input signal voltage, adjust the chroma input signal until the B output
voltage = 5Vp−p. At this point, th R and G voltages will fall within the specified limits. Luma
voltage = 23V.
Note 8. Tested with B output = 5Vp−p, luma voltage = 23V.
Note 9. No chroma input voltage and normal reference signal input voltage.
Note10. Testd with input signal voltage, normal reference signal voltage and B output = 5Vp−p.
