1. Input the standard colour bar signal
(the same pattern as that of JPN-
8CH) of N358 into AV1.
2. Connect CH1 of oscilloscope to
TP821 (G output).
3. Connect CH2 of oscilloscope to
TP820 (B output).
1. Input the standard colour bar signal
(the same pattern as that of JPN-
8CH) of N358 into AV1.
2. Connect the oscilloscope to TP820
(B output).
1. Input the standard colour bar signal

1. Adjust so as to get 100% white level
identical with that of green.
Adjust N358 SCOLOR so as to get the
colour bar signal blue amplitude
(black level - peak level) equal to 2.0V
± 0.05Vp-p.
1. Adjust N358TINT so as to get the
colour bar signal magenta amplitude
(black level-peak level) equal to 1.7V
± 0.05Vp-p.
1. The indication changes from WAIT
to SEND, and after the lapse of one
second WAIT is restored. Thus, N443,
PAL-M adjustment is completed.
1. Adjust R-ADJ to 4.0V ± 0.05V.
(DAC 6ch)
get the normal screen.
