C.T.1, and C.T.1' crosstalk 1 (f=50MHz) and (F=110 MHz)
1. The conditions shall be as specified in the electrical
characteristics table.
2. Input SG3 (or SG4) to pin
(R-ch) only, measure the output
waveform amplitude of T.P25 (T.P30 or T.P35) at this time to let
the value be V

.
3. Crosstalk C.T.1 is found by:
C.T.2 and C.T.2' crosstalk 2 (f=50MHz) and (f=110MHz)
1. Change input pin from pin
output in the same manner as in the case of C.T.1 and C.T.1'.
2. Crosstalk C.T.2 is found by:
(R-ch) to pin
(G-ch), and read
C.T.3 and C.T.3' crosstalk 3 (f=50MHz) and (f=110MHz)
1. Change input pin from pin
output in the same manner as in the case of C.T.1 and C.T.1'.
2. Crosstalk C.T.3 is found by:
(R-ch) to pin
(G-ch), and read
Tr and Tf pulse characteristics 1 and pulse characteristics 2
1. The conditions shall be as specified in the electrical
characteristics table.
2. Use an active probe to measure rise Tr1 and fall Tf1 at 10 to 90%
of input pulse.
3. Then, measure rise Tr2 and fall Tf2 at 10 to 90% of output pulse
with an active probe.
4. Pulse characteristics Tr and Tf is found by:
V14th clamping pulse threshold voltage
1. The conditions shall be as specified in the electrical
characteristics table.
2. Gradually reduce SG6 level at this time, while monitoring output
(in a range of 2.0V
DC
), and measure SG6 level when output
becomes 0V.
W14 clamping pulse operating min. width
Gradually reduce SG6 pulse width while monitoring output this time
under the conditions of V14th. In this case as well, measure SG6
pulse width when output becomes 0V.
OTr OSD pulse characteristics 1 and OTf OSD pulse
characterisitics 2
1. The conditions shall be as specified in the electrical
characteristics table.
2. Use an active probe to measure rise OTr and fall OTf at 10 to
90% of output pulse.
Oaj1 OSD adjustment control characteristics (at max.) and
Oaj1 relative OSD adjustment control characteristics (at
max.)
1. The conditions shall be as specified in the electric characteristics
table.
2. Read the output width of T.P25 (T.P30 or T.P35) at this time, and
let the reading be V
ORA
(V
OGA
or V
OBA
) to let it be Oaj1,
respectively.
3. Relative OSD adjustment control characteristics
Oaj1 is found
by:
Oaj1=V

Oaj2 OSD adjustment control characteristics (at min.) and
Oaj2 relative OSD adjustment control characteristics (at min.)
1. Follow the electrical characteristics table except changing V36 to
0V.
2. Read the output amplitude of T.P25 (T.P30 or T.P35) at this time,
and let the reading be V
ORB
(V
OGB
or V

) to let it be Oaj2,
respectively.
3. Relative OSD adjustment control characteristics
Oaj2 is found
by:

OSDth OSD input threshold voltage
1. The conditions shall be as specified in the electrical
characteristics table.
2. Gradually reduce SG8 level at this time, while monitoring output,
and measure SG8 level when output is stopped to let the value
be OSDth.
V1th BLK input threshold voltage
1. The conditions shall be as specified in the electrical
characteristics table.
2. Verify at this time that no signal is output with a timing in which
output is synchronized with SG8.
3. Gradually reduce SG8 level at this time, while monitoring output,
and measure SG8 level when blanking period expires to let the
value be V1th.
