Measure the 10 to 90% rise / fall times in the waveform of the output pin (pin 21 when X = B, pin 19 when X = G, and pin 14 when X = R), and convert this to a through-rate. Signal output S / N * Test condition 5 (CP mode, fixed polarity) * Input : no signal Noise measurement band DC to 6MHz Change SW27 from a to b, and adjust VR27 while looking at the waveform of an output pin (pin 21, pin 19, pin 14) so that the difference between the 0 and black levels becomes 0. Measure the noise voltage (measurement band: ~6MHz) of the output pins in this state. Repeat this measurement for each output pin.

Obtain a voltage difference ratio of 2:1 and set this as the maximum value of the characteristics. Next, set the voltage applied to pin 43 to 2.5V by turning VR43 fully in the opposite direction, thereby minimizing the characteristics. Obtain a voltage difference ratio of 2:1 and thereby minimize the value of the characteristics in the same way the maximum value was measured. When measuring channel R (X = R) change SW1 from OFF to ON, turn VR1 clockwise and anticlockwise with R In1 as the input pin, and thus measure output pin 14 in the same way as channel B.

Note 1: Note 2: Note 3: Note 4:
This setup is based on the initial setup condition before starting various measurements. Symbols a, b, ON, and OFF show the SW setup. The underlined setup shows that it is to be changed when the setup of test condition 1 is specified as default. The signal names in the SIG column (CP1, CP2, POL *** ) show that the specified signals are applied on a fixed basis. (SIG) applies signals to any one pin according to items.
