BUS CONTROLLED 3CH VIDEO PRE-AMP FOR CRT DISPLAY MONITOR

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),

and is treated as Oaj1.

Note50) Relative characteristics Oaj1 is calculated by the equation below:

Oaj1=VOUT(33)/VOUT(38)ÅAVOUT(38)/VOUT(41)ÅAVOUT(41)/VOUT(33)

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.

Measure the SG6 level when the output reaches 0V. The measured value is called VthOSD.

Note56) 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.

Note57) Measure the amplitude output is blanked by the SG7 at OUT(33,38,41). The measured value is

called VOUT(33,38,41), and is treated as HBLK1.

Note60) 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.
