Tf Relative pulse characteristics2
Relative characteristics Tf is calculated by the difference in the
output between the channels.
VthCP Clamp pulse threshold voltage
Turn down the SG5 input level gradually from 5.0V
P-P
, monitoring
the waveform output.
Measure the top level of input SG5 at when the output pedestal
level is start to going down or unstable.
WCP Clamp pulse minimum width
Decrease the SG5 pulse width gradually from 0.5 μs, monitoring the
output. Measure the input SG5 pulse width (a point of 1.5V)
when the output pedestal voltage turm decrease with unstable.
OTr OSD pulse characteristics1
Measure the time needed for the output pulse to rise from 10% to
90% (OTR) with an active prove.
OTf OSD pulse characteristics2
Measure the time needed for the output pulse to fall from 90% to
10% (OTF) with an active prove.
Oaj1 OSD adjust control characteristics1
Measure the amplitude output at OUT (24, 28, 31). The measured
value is called VOUT (24, 28, 31), and is treated as Oaj1.
Pedestal voltage temperature characteristics 2 is calculated by the
equation below:
P =PDC1-PDC3
DCH
Oaj1 OSD adjust control relative characteristics1
Relative characteristics Oaj1 is calculated by the equation below:
Oaj1=VOUT (24)/VOUT (28),
VOUT (28)/VOUT (31),
VOUT (31)/VOUT (24)
Oaj2 OSD adjust control characteristics2
Measuring condition and procedure are the same as described in
Oaj1.
Oaj2 OSD adjust control relative characteristics2
Measuring condition and procedure are the same as described in
Oaj1.
OBLK OSD adjust control characteristics3
Measuring condition and procedure are the same as described in
Oaj1.
OBLK OSD adjust control relative characteristics3
Measuring condition and procedure are the same as described in
Oaj1.
VthOSD OSD input threshold voltage
Reduce the SG6 input level gradually, monitoring output. Measure
the SG6 level when the output reaches 0V. The measured value is
called VthOSD.
VthBLK OSD BLK input threshold voltage
Confirm that output signal is being blanked by the SG6 at the time.
Monitoring to output signal, decreasing the level of SG6. Measure
the top level of SG6 when the blanking period is disappeared. The
measured value is called VthBLK.
VthRET Retrace BLK input threshold voltage
Confirm that output signal is being blanked by the SG7 at the time.
Monitoring to output signal, decreasing the level of SG7. Measure
the top level of SG7 when the blanking period is disappeared. The
measured value is called VthRET.

PRELIMINARY
Some parametric limits are subject to change.
DCH
P Pedestal voltage temperature characteristic1
Measure the pedestal voltage at 25°C. The measured value is
called PDC1.
Measure the pedestal voltage at temperature of -20°C. The
measured value is called PDC2.
Pedestal voltage temperature characteristics 1 is calculated by the
equation below:
P =PDC1-PDC2
DCH
P Pedestal voltage temperature characteristic2
DCH
Measure the pedestal voltage at 25°C. The measured value is
called PDC1.
Measure the pedestal voltage at temperature of 75°C. The
measured value is called PDC3.
