Set the amplitude of #54 to 20 mV
Set the unicolor to the maximum (111111), set the brightness to the center (1000000), set the RGB cutoff to the
center (10000000), turn the Y mute off (0), turn test mode on (0), and set the picture sharpness to the maximum
(111111).
Connect an emitter-follower to TP13 (R OUT) and use a spectrum analyzer to observe TP13 (R OUT).
Seek the peak point frequency F
