BUS CONTROLLED 3CH VIDEO PRE-AMP FOR CRT DISPLAY MONITOR
Note1) Measuring conditions are as listed in supplementary Table. Measured with a current meter
at test point IA.
Note2) Measuring conditions are as listed in supplementary Table. Measured with a current meter
at test point IB.
Note3)
Decrease V34 gradually, and measure the voltage when the bottom of waveform output is
distorted. The voltage is called VOL.
Next, increase V34 gradually, and measure the voltage when the top of waveform output is
distorted. The voltage is called VOH.
Voltagr Vomax is calculated by the equation below:
(V)
Vomax = VOH - VOL
VOH
5.0
Waveform output
Note4)
VOL
0.0
Increase the input signal(SG2) amplitude gradually, starting from 700mVp-p. Measure the
amplitude of the input signal when the output signal starts becoming distorted.
Note5)
Note6)
Input SG1, and read the amplitude output at OUT(33,38,41). The amplitude is called
VOUT(33,38,41).Maximum gain GV is calculated by the equation below:
VOUT
GV=20 LOG
(dB)
0.7
Relative maximum gain GV is calculated by the equation below:
GV=VOUT(33)/VOUT(38), VOUT(38)/VOUT(41), VOUT(41)/VOUT(33)
Note7)
Note8)
Measuring the amplitude output at OUT(33,38,41). The measured value is called VOUT(33,38,41).
Main contrast conrol characteristics VC1 is calculated by the equation below:
VOUT
VC1=20 LOG
(dB)
0.7
Relative characteristics VC1 is calculated by the equation below:
VC1=VOUT(33)/VOUT(38) , VOUT(38)/VOUT(41) , VOUT(41)/VOUT(33)
Note9) Measuring condition and procedure are the same as described in Note7.
Note10) Measuring condition and procedure are the same as described in Note8.
Note11) Measuring the amplitude output at OUT(33,38,41). The measured value is called VOUT(33,38,41).
Note12) Measuring condition and procedure are the same as described in Note8.
