Measure the time needed for the input pulseto fall from 90 % to 10 % (Tf1) and for the
output pulse to fall from 90 % to 10 % (Tf2) with an active prove.
Pulse characteristics TF is calculated by the equations below :
Measure the pedestal voltage at temperature of 75 C. The measured value is called
PDC3.Pedestal voltage temperature characteristics 2 is calculated by the equation below:
Control the contrast in order that the amplitude of output signal is 2.0Vp-p.
Control the brightness in order that the Black level of output signal is 1.0V.
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 :
Turn down the SG4 input level gradually from 5.0Vp-p, monitoring the waveform
output.Measure the top level of input pulse when the output pedestal voltage turn
decrease with unstable.
Decrease the SG4 pulse width gradually from 0.5us, monitoring the output. Measure the SG4
pulse width (a point of 1.5V) when the output pedestal voltage turn decrease with unstable.
Measure the pedestal voltage at 25 C. The measured value is called PDC1.
Measure the pedestal voltage at temperature of - 20 C. The measured value is
called PDC2.Pedestal voltage temperature characteristics 1 is calculated by the
equation below:
Relative Pulse characteristics1 Tr is calculated by the equation below:
Relative Pulse characteristics2 Tf is calculated by the equation below:
TENTATIVE
Tr =VOUT(2) - VOUT(5) , VOUT(5) - VOUT(9) , VOUT(9) - VOUT(2)
Tf = VOUT(2) - VOUT(5) , VOUT(5) - VOUT(9) , VOUT(9) - VOUT(2)
