Set the amplitude of #54 to 20 mV
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).
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 V
Next, set the picture sharpness to the minimum (000000). As in 5), when the frequencies are 100 kHz and 2.4
