VikP Threshold color killer on
1. Input VS (level:variable) from pin 36 IN at input level 0dB.
2. Lower the input level whth monitoring the output amplitude at pin
20 and measure the input level when output amplitude isnot
found.
KillP Residual color leakage at killer on
1. Input VS (level:-45dB) from pin 36 IN.
2. Measure the output amplitude at pin 20.
APC1 APC pull-in range 1
1. Input VS (f=eb=ec=variable) from pin 36 IN.
2. Change the input signal frequency and measure the frequency
range from the point at which signal is output to pin 20 and to the
point that no signal is output to the pin. The reference value is
3.579545MHz.
R/B P Ratio of (R-Y/B-Y)
1. Input VS (eb=single chroma=ec+100kHz) from pin 36 IN.
2. V20 is the output amplitude at pin 20.
3. V18 is the output amplitude at pin 18.
4. R/B P is defined as follows:
