Note 13) Measur the amplitude output at OUT(29,32,35). The measured value is called VOUT(29,32,35).
Sub contrast control characteristics VSC1 is calculated by the equation below:
VSC1=20Log(VOUT/0.7) (dB)
Note 14) Relative characteristics VSC1 is calculated by the equation below:
VCS1=VOUT(29)/VOUT(32),
VOUT(32)/VOUT(35),
VOUT(35)/VOUT(29).
Note 15) Measuring condition and procedure are the same as described in Note13.
Note 16) Measuring condition and procedure are the same as described in Note14.
Note 17) Measuring condition and procedure are the same as described in Note13.
Note 18) Measuring condition and procedure are the same as described in Note14.
Note 19) Measure the amplitude output at OUT(29,32,35). The measured value is called VOUT(29,32,35).
Main/Sub contrast conrol characteristics VMSC is calculated by the equation below:
VMSC=20log(VOUT/0.7) (dB)
Note 20) Relative characteristics VMSC is calculated by the equation below:
VMSC=VOUT(29)/VOUT(32) ,
VOUT(32)/VOUT(35) ,
VOUT(35/VOUT(29)
Note 21) Measure the amplitude output at OUT(29,32,35). The measured value is called VOUT(29,32,35),
and is ttreated as ABL1.
Note 22) Relative characteristics ABL1 is calculated by the equation below:
ABL1=VOUT(29)/VOUT(32) ,
VOUT(32)/VOUT(35) ,
VOUT(35)/VOUT(29)
Note 23) Measuring condition and procedure are the same as described in Note21.
Note 24) Measuring condition and procedure are the same as described in Note22.
Note 25) Measure the DC voltage at OUT(29,32,35) with a voltmeter. The measured value is called
VOUT(29,32,35), and is ttreated as VB1.
Note 26) Relative characteristics VB1 is calculated by the difference in the output between the channels.
VB1=VOUT(29)-VOUT(32) ,
VOUT(32)-VOUT(35) ,
VOUT(35)-VOUT(29)
Note 27) Measuring condition and procedure are the same as described in Note25.
Note 28) Measuring condition and procedure are the same as described in Note26.
Note 29) Measuring condition and procedure are the same as described in Note25.
