Measure the time needed for the output pulse to rise from 10% to 90% (OTR) with an active prove.
Measure the time needed for the output pulse to fall from 90% to 10% (OTF) with an active prove.
Measure the amplitude output at OUT(2,5,9). The measured value is called VOUT(2,5,9),
and is treated as Oaj1.
Measuring condition and procedure are the same as described in Note48.

Measuring the amplitude output at OUT(2,5,9). The measured value is called O
Relative OSD BLK characteristics
Reduce the SG5 input level gradually, monitoring output.Measure the SG5 level when
the output reaches 0V. The measured value is called VthOSD.
Supply 5V to V16,and then measure input current into Pin16
Supply 0V to V16,and then measure input current into Pin16
Supply 5V to V19,and then measure input current into Pin19
Supply 0V to V19,and then measure input current into Pin19
Supply 5V to V20,and then measure input current into Pin20
Supply 0V to V20,and then measure input current into Pin20
Supply 5V to V27,and then measure input current into Pin27
Relative characteristics
Supply 0V to V(24,25,26)and then measure input current into Pin(24,25,26)
Confirm that output signal is being blanked by the SG5 at the time.
Monitoring to output signal, decreasing the level of SG5. Measure the top level of SG6 when
the blanking period is disappeared. The measured value is called VthBLK.
Supply 0V to V27,and then measure input current into Pin27
Supply 5V to V(24,25,26)and then measure input current into Pin(24,25,26)
TENTATIVE
IIC BUS controled 3channel video pre-amplifier for LCD display monitor.
Oaj1 = VOUT(2) / VOUT(5), VOUT(5) / VOUT(9), VOUT(9) / VOUT(2)
