3-7. Chrominance Signal System
(!)Frequency responce:
At chroma signal test pin
NTSC: 3.58MHz
± 1MHz + 1, -3dB
PAL : 4.43MHz
± 1MHz + 1, -3dB
(2)Demodulation -axis phase difference :
go• ± 1·
(3)Subcarrier frequency syncronizing range:
Lock in range NTSC : 3.579545 MHz±200 Hz
PAL : 4.43361875MHz±300Hz
(4)Phase Difference (only NTSC):
Below 2°
(Burst frequency ± l0Hz, Burst level
+6dB, -1 2dB, Change in atmospheric
temperature l0 "C, Where positions of
the H-SYNC signal
and the burst
signal change within FCC standards)
(5)Delay compensation :
Delay time compensation error from
luminance and Pn,Pu channel is less
than 0.02µSEC.
{6)Color killer operating point:
Automatically operat ed when the burst
level is 5 ±
1 IRE.
(7)Adjusters : Chroma level Above ±6dB
Chroma phase
± 15°
3-8. Deflection and Sync Systems
(1) Picture size: a) NORMAL SCAN (4:3)
1 % over-scan of effective CRT screen
b)UNDERSCAN (4:3)
Approx. - 7.5% of effective CRT screen
c)UNDERSCAN (16:9)
Width is the same as UNDER SCAN
(4:3)
and the aspect ratio is 16:9.
(2)Stability of Raster Size
When
CONTRAST and BRIGHTNES S
are preset, when the APL changes
within
0o/'o-100%, there is a variation of
1% or less.
(3)Deflection distortion
a) Deflection of
axis
Below 0.5% of the height of the screen
b) Overall screen distortion
B~low 0.5% of the height of the screen
{4)AFC time constant
NORMAL : 2mSec.
FAST : 0.5mSec.
SLOW : 7mSec.
{S)Sync stability: Operation will be stable when the
input signal
falls within the following
parameters :
Internal sync :
Variati on of
± 6dB in rated video
input level values
External sync :
{6)High voltage:
Negat ive voltage applied to external
sync input t erminal
0.3 to
8Vp-p
a)Output volt age
TM20-30RH/RP : 25kV
TM20-20RH /RP : 25kV
TM14-20RH /RP : 25kV
b)Voltage fluctuat ions:
Within
± 1 % for beam current of
between O to
450µA with 150 µA as
a reference
(7) Convergence :
20
