1. No signal is input to pin 21.
2. Check the DC voltage of pin 20 (PAL ID) and pin 17
(NTSC ID). Define these as PI and NI respectively.
3. Externally vary the voltage applied to pins 20 and 17.
Define the ID voltages for PAL color and NTSC color
as PC and NC respectively.
4. Define the difference between the ID voltages in the
above no-signal state and the ID voltages in the
forced color state as PI and NI respectively.

1. To pin 21, input a 3.58MHz / 4.4MHz continuous
wave with an amplitude of 100mVp-p.
3.58MHz / 4.4MHz continuous wave
2. Vary the above input frequency. Using the held
pull-in frequency, compare to
3N and 4N and measure
3N Ref 3579545Hz
4N Ref 4433618Hz
3. Measure in 3N and 4N Forced modes.
