Note49) Measure the time needed for the output pulse to rise from 10% to 90%(OTR) with an active prove.
Note50) Measure the time needed for the output pulse to fall from 90% to 10% (OTF) with an active prove.
Note51) Measure the amplitude output at OUT(24,28,31). The measured value is called VOUT(24,28,31),
and is treated as Oaj1.
Note52) Relative characteristics
Oaj1 is calculated by the equation below:
Oaj1=VOUT(24)/VOUT(28), VOUT(28)/VOUT(31), VOUT(31)/VOUT(24)
Note53) Measuring condition and procedure are the same as described in Note51.
Note54) Measuring condition and procedure are the same as described in Note52.
Note55) Measuring condition and procedure are the same as described in Note51.
Note56) Measuring condition and procedure are the same as described in Note52.
Note57) Reduce the SG6 input level gradually, monitoring output.
Measure the SG6 level when the output reaches 65~75% of first voltage. The measured value is
called VthOSD1.
Note58) Reduce the SG6 input level gradually, monitoring output.
Measure the SG6 level when the output reaches 0V. The measured value is called VthOSD2.
Note59) 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.
Note60) Measure the amplitude output at OUT(24,28,31). The measured value is called VOUT(24,28,31),
and is treated as Ohaj1.
Note61) Measure the amplitude output at OUT(24,28,31). The measured value is called VOUT(24,28,31),
and is treated as Ohaj2.
Note62) 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.
