Note 30) Measuring condition and procedure are the same as described in Note26.
Note 31) First, SG3 to 1MHz is as input signal. Input a resister that is about 2K to offer the voltage at input
pins(2,6,11) in order that the bottom of input signal is 2.5V. Control the main contrast in order that
the amplitude of sine wave output is 4.0Vp-p. Control the brightness in order that the bottom of sine
wave output is 2.0Vp-p. By the same way, measure the output amplitude when SG3 to 50MHz is as
input signal.The measured value is called VOUT(29,32,35).Frequency characteristics FC1(29,32,35)
is calculated by the equation below:
FC1=20 log[VOUT(Vp-p)/output amplitude when inputed SG3(1MHz):4Vp-p](dB)
Note 32) Relative characteristics FC1 is calculated by the difference in the output between the channels.
Note 33) Measuring condition and procedure are the same as described in Note31,expect SG3 to 150MHz.
Note 34) Relative characteristics FC1' is calculated by the difference in the output between the channels.
Note 35) SG3 to 1MHz is as input signal. Control the main contrast in order that the amplitude of sine wave
output is 1.0Vp-p. By the same way, measure the output amplitude when SG3 to 150MHz is as input
signal.The measured value is called VOUT(29,32,35).Frequency characteristics FC2(29,32,35) is
calculated by the equation below:
FC1=20log[VOUT(Vp-p)/output amplitude when inputed SG3(1MHz):4Vp-p](dB)
Note 36) Relative characteristics FC2 is calculated by the difference in the output between the channels.
Note 37) Input SG3 (50MHz) to pin2 only, and then measure the waveform amplitude output at
OUT(29,32,35).The measured value is called VOUT(29,32,35).Crosstalk CT1 is calculated by the
equation below:
CT1=20 log [VOUT(29,32)/VOUT(35)] (dB)
Note 38) Measuring condition and procedure are the same as described in Note37,expect SG3 to 150MHz.
Note 39) Input SG3 (50MHz) to pin6 only, and then measure the waveform amplitude output at
OUT(29,32,35).The measured value is called VOUT(29,32,35).Crosstalk CT2 is calculated by the
equation below:
CT2=20 log [VOUT(29,35)/VOUT(32)] (dB)
Note 40) Measuring condition and procedure are the same as described in Note39,expect SG3 to 150MHz.
Note 41) Input SG3 (50MHz) to pin11 only, and then measure the waveform amplitude output at
OUT(29,32,35).The measured value is called VOUT(29,32,35).Crosstalk CT2 is calculated by the
equation below:
CT3=20 log [VOUT(32,35)/VOUT(29)] (dB)
Note 42) Measuring condition and procedure are the same as described in Note41,expect SG3 to 150MHz.
Note 43) Control the main contrast (00H) in order that the amplitude of output signal is 4.0Vp-p.
Control the brightness (V30) in order that the Black level of output signal is 2.0V.
Measure the time needed for the input pulse to rise from 10 % to 90 % (Tr1) and for the output pulse
to rise from 10 % to 90 % (Tr2) with an active prove.
Pulse characteristics Tr is calculated by the equations below :
Tr=
[ (Tr2) -(Tr1) ]
(nsec)
