Note43) Control the main contrast (00H) in order that the amplitude of output signal is 3.0Vp-p.
Control the brightness (V34) 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 probe.
Pulse characteristics Tr is calculated by the equations below :
Note44) 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 probe.
Pulse characteristics Tf is calculated by the equations below :
Note45) Turn down the SG5 input level gradually from 5.0Vp-p, monitoring the waveform output.
Measure thetop level of input pulse when the output pedestal voltage turn decrease with unstable.
Note46) Decrease the SG5 pulse width gradually from 0.5us, monitoring the output. Measure the SG5
pulse width (a point of 1.5V) when the output pedestal voltage turndecrease with unstable.
