Enter SIG3 to (A) and measure the ratio between
the output amplitude (white to black) and input
amplitude of TP43.
Enter SIG3 to (A) and measure the ratio between
the output amplitude (white to black) and input
amplitude of TP43.
Enter SIG3 to (A) and measure the ratio between
the output amplitude (white to black) and input
amplitude of TP43.
Assume that the output amplitude of TP43 when
SIG1 (0dB, 100kHz) is entered to (A) is 0dB.
Change the input signal frequency to change and
determine the frequency at which the output
amplitude becomes -3dB.
FCH when the serial bus LPF = HIGH, CL = 150pF
and FCL when LPF = LOW
Enter SIG8 to (A). Measure the delay time from the
input signal 2T pulse peak to the peak of TP43
non-inverted output.
Measure TP38 output. DC IO = ±1mA
COMBMX when COMB = 63 and COMBMN when
COMB = 0
Measure the TP50 voltage by setting VCC2 = 8,5V
and SIG center level changeover = low voltage
mode.
Measure the TP50 voltage by setting VCC2 = 7V
and SIG center level changeover = high voltage
mode.
Set VCC2 = 8.5V and SIG center level changeover
= low voltage mode and enter SIG4 (VL = 0mV)
into (A). Adjust the serial bus BRIGHT to set TP43
output to 3Vp-p and measure the DC voltage of
TP40, TP43, and TP45.
Set VCC2 = 7V and SIG center level changeover =
high voltage mode, and enter SIG4 (VL = 0mV) to
(A). Adjust the serial bus BRIGHT to set the TP43
output to 3Vp-p and measure the DC voltage of
TP40, TP43, and TP45.
Determine the maximum of differences among
measurements of TP40, TP43, and TP45 of VOUT
of previous item.
Measure the change rate of the black level of
TP40, TP43, and TP45 outputs when SIG2 is
entered to (A) and BRT is changed from 128 to
255.
Measure the change rate of the white level of
TP40, TP43, and TP45 outputs when SIG2 is
entered to (A) and BRT is changed from 128 to 0.
Measure the difference between non-inverted and
inverted levels of TP38 output when (A) = SIG2 is
entered and COMW is set to 255.
Measure the difference between non-inverted and
inverted levels of TP38 output when (A) = SIG2 is
entered and COMW is set to 0.
