(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 (100mVp-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 = 600kHz).
(9)
Input 4N rainbow color bar signal to pin 42 (Chroma IN), and perform the same
measurement as the 3N signal.
