Tr Pulse characteristics1
Tf Pulse characteristics2
1. Measuring conditions are as given in Supplementary Table.
2. Measure the time needed for the input pulse to rise from 10% to
90% (Tr1) and to fall from 90% to 10% (Tf1) with an active prove.
3. Measure the time needed for the output pulse to rise from 10%
to 90% (Tr2) and to fall from 90% to 10% (Tf2) with an active
prove.
4. Pulse characteristics Tr and Tf are calculated by the equation
below:
Tr (nsec)= (Tr2)

V14th Clamp pulse threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Turn down the SG5 input level gradually, monitoring the output
(about 2.0 VDC). Measure the SG5 input level when the output
reaches 0V.
W14 Clamp pulse minimum width
Under the same conditions as given in Note 19, reduce the SG5
pulse width gradually, monitoring the output. Measure the SG5
pulse width when the output reaches 0V.

OTr OSD pulse characteristics1
OTf OSD pulse characteristics2
1. Measuring conditions are as given in Supplementary Table.
2. Measure the time needed for the the output pulse to rise from
10% to 90% (OTr) and to fall from 90% to 10% (OTf) with an
active prove.
Oaj1 OSD adjusting control characteristics (maximum)
Oaj1 OSD adjusting control relative
characteristics (maximum)
1. Measuring conditions are as given in Supplementary Table.
2. Measure the amplitude at T.P25 (30 or 35). The measured value
is called V
ORA
(V
OGA
or V
OBA
), and is treated as Oaj1.
3. OSD adjusting control relative characteristics
Oaj1 are
calculated by the equation below:
Oaj2 OSD adjusting control characteristics (minimum)
Oaj2 OSD adjusting control relative
characteristics (minimum)
1. Measuring conditions are as given in Supplementary Table,
except that V36 is set to 0V.
2. Measure the amplitude at T.P25 (30 or 35). The measured value
is called V
ORB
(V
OGB
or V
OBB
), and is treated as Oaj2.
3. OSD adjusting control relative characteristics
Oaj2 are
calculated by the equation below:
OSDth OSD input threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Reduce the SG7 input level gradually, monitoring output.
Measure the SG7 level when the output reaches 0V. The
measured value is called OSDth.
V1th BLK input threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Make sure that signals are not being output synchronously with
SG7 (blanking period).
3. Reduce the SG7 input level gradually, monitoring output.
Measure the SG7 level when the blanking period disappears.
The measured value is called V1th.
