MEASUREMENT METHOD
Set the bus control data to the preset value.
Input a signal like that shown in the diagram below to TP54, turn the Y mute off (0), and adjust the amplitude of
#54 to 0.7 V_p-p.
Set the unicolor to the maximum (111111), increase the picture sharpness from the minimum to a level where the
R OUT waveform is not distorted.
Measure the phase differences T_VM24, T_VMFP, and T_VM2T between TP1 (VSMOUT) and TP13 (R OUT) when
the signal is an FVSM sine wave, a 2T pulse, and a 2.4-MHz signal, as shown in the diagram below. (To make a
waveform at TP1, reverse the waveform at TP13 using an oscilloscope.)

Note 1: When testing, see the picture sharpness test circuit diagram. First turn ACB mode off (bus control).
Note 2: Ensure the composite signal is always input to pin 38 (SYNC IN).
