(1)
Activate the test mode (S26-ON, Sub Add 02 ; 01h).
(2)
Set as follows : band pass filter Q = 2, crystal clock = conforming to 3.579 / 4.43MHz,
gate = normal status.
(3)
Input 3N composite sine wave signal (1Vp-p) to pin 42 (Chroma IN).
(4)
Measure frequency characteristic of B-Y output of pin 36 and measure the peak
frequency, too.
(5)
Changing fo to 0, 500, 600 and 700 by the bus control and measure peak frequencies
respectively with different fo.
(6)
For measuring frequency characteristic as fo is 4.43, use 4.43MHz crystal clock.
Measure the following items in the same manner.
