MEASURING METHOD
(1) Activate the test mode (S26-ON, Sub Add 02 ; 08h).
(2) Connect band pass filter (Q = 2), set crystal mode to conform to European, Asian
system and set the gate to normal status.
(3) Input 3N rainbow color bar signal (100 mVp-p) to pin 42 (Chroma IN).
(4) Measure phase shift of B-Y color difference output of pin 36.
(5) While shifting color phase (tint) from minimum to maximum by the bus control, measure
phase change of B-Y color difference output of pin 36. On the condition that 6 bars in
the center have the peak level (regarded as center of color phase), the side of 5 bars is
regarded as positive direction while the side of 7 bars is regarded as negative direction
when the 5 bars or the 7 bars are in the peak level. Based on this assumption, open

angle toward the positive direction is expressed as
θ1 and that toward the negative direction is
expressed as θ2 as viewed from the phase
center. θ1 and θ2 show the tint control sharing
range.
(6) Variable range is expressed by sum of θ1
sharing range and θ2 sharing range.
θT = θ1 + θ2

(7) While shifting color phase from minimum to maximum with the bus control, measure
phase shift of B-Y color difference output of pin 36. When center 6 bars have peak level,
value of color phase bus step is expressed as θTin.
(8) While shifting color phase from minimum to maximum with the bus control, measure
values of color phase bus step corresponding to 10% and 90% of absolutely variable
phase shift of B-Y color difference output of pin
36. The range of color phase shifted by the bus
control is expressed as While shifting color phase
from minimum to maximum with the bus control,
measure phase shift of B-Y color difference output
of pin 36. When center 6 bars have peak level,
value of color phase bus step is expressed as Tin
(conforming to TV mode, fo = 600 kHz).

(9) Input 4N rainbow color bar signal to pin 42 (Chroma IN), and perform the same
measurement as the 3N signal.
