SG3 to 1MHz is as input signal. Control the main contrast in order
that the amplitude of sine wave output is 1.0V
measure the output amplitude when SG3 to 150MHz is as input
signal.

C.T.1 Crosstalk1 (f=50MHz)
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 C.T.1 is calculated by the equation
below:
C.T.1' Crosstalk1 (f=150MHz)
Measuring condition and procedure are the same as described in
C.T.1, expect SG3 to 150MHz.
C.T.2 Crosstalk2 (f=50MHz)
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 C.T.2 is calculated by the equation
below:
C.T.2' Crosstalk2 (f=150MHz)
Measuring condition and procedure are the same as described in
C.T.2, expect SG3 to 150MHz.

C.T.3 Crosstalk3 (f=50MHz)
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 C.T.2 is calculated by the equation

Tr Pulse characteristics1 (4V
Control the main contrast (00H) in order that the amplitude of output
signal is 4.0V
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:
Tf Pulse characteristics2 (4V
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:
VthCP Clamp pulse threshold voltage
Turn down the SG5 input level gradually from 5.0V
the waveform output.
Measure the top level of input pulse when the output pedestal
voltage turn decrease with unstable.
WCP Clamp pulse minimum width
Decrease the SG5 pulse width gradually from 0.5 s, monitoring the
output. Measure the SG5 pulse width (a point of 1.5V) when the
output pedestal voltage turn decrease with unstable.
