MEASUREMENT METHOD
1) Input signal 1 (f = 100 kHz, picture amplitude 0.2 V_p-p) to pin 53 and
adjust drive data so that the picture period amplitude of pins 14 and 15
equals that of pin 13.
2) Set SW₅₄ to C.
3) Measure the voltages on pins 17, 18, and 19 and apply the measured
voltages to the pins from an external power supply.
4) Set the subaddress (11) data to (50).
5) According to the voltage on pins 13, 14, and 15 in Figure 1 below,
determine the phase of ACB input pulse.

Note : The phase starts after the V-BLK period. The picture period after
the falling edge of FBP input is 1 H ; then, every time H-BLK ends,
the period is 2 H, 3 H, and so on.
C ^{6) According to pins 13, 14, and 15 the voltage on, determine the ACB input}
pulse amplitude (amplitude from the BLK level at RGB-BLK OFF).
