1) Set the bus control data to the preset value.
2) Set SW54 to A and input a sine wave to TP54A.
3) Set the amplitude of #54 to 20 mVp-p.
4) Set the unicolor to the maximum (111111), the brightness to the center (1000000), RGB cutoff to the center
(10000000), and turn the Y mute off (0).
5) Set the picture sharpness to the maximum (111111). Connect an emitter-follower to TP13 (R OUT). When the
frequencies are 100 kHz and 2.4 MHz, measure the respective V100 and V24 amplitudes.
6) Next, set the picture sharpness to the minimum (000000). As in 5), when the frequencies are 100 kHz and 2.4 MHz,
measure the V100 and V24 amplitudes respectively.
7) Calculate GMAX and GMIN from the following formula.
GMAX, GMIN [dB] = 20 ×og (V24 ÷ V100)

1) Repeat steps 1) to 4) of P17.
2) Set the picture sharpness to the center (100000)
3) Connect an emitter-follower to TP13 (R OUT). When the frequencies are 100 kHz and 2.4 MHz, measure the V100
and V24 amplitudes respectively.
4) Calculate GCEN from the following formula.
GCEN [dB] = 20 ×og (V24 ÷ V100)
Note 1: When testing, see the picture sharpness test circuit diagram.
Note 2: Ensure the composite signal is always input to pin 38 (SYNC IN).
