Note47) Measure the time needed for the output pulse to rise from 10% to 90% (OTr) with an active probe.
Note48) Measure the time needed for the output pulse to fall from 90% to 10% (OTf) with an active probe.
Note49) Measure the amplitude output at OUT(33,38,41). The measured value is called VOUT(33,38,41),
Note50) Relative characteristics
Note51) Measuring condition and procedure are the same as described in Note49.
Note52) Measuring condition and procedure are the same as described in Note50.
Note53) Measuring condition and procedure are the same as described in Note49.
Note54) Measuring condition and procedure are the same as described in Note50.
Note55) Reduce the SG6 input level gradually, monitoring output.
Note56) Confirm that output signal is being blanked by the SG6 at the time.
Note57) Measure the amplitude output is blanked by the SG7 at OUT(33,38,41). The measured value is
Note60) Confirm that output signal is being blanked by the SG7 at the time.
and is treated as Oaj1.
Measure the SG6 level when the output reaches 0V. The measured value is called VthOSD.
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.
called VOUT(33,38,41), and is treated as HBLK1.
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.
Oaj1=VOUT(33)/VOUT(38)ÅAVOUT(38)/VOUT(41)ÅAVOUT(41)/VOUT(33)
Oaj1 is calculated by the equation below:
