Conditions
Enter SIG5 (VL = 0mV) to (A) and measure the
difference between the black level of TP45 output
when R-BRT = 128 and the black level of output
when R-BRT = 0 and R-BRT = 255.
Enter SIG5 (VL = 0mV) to (A) and measure the
difference between the black level of TP40 output
when B-BRT = 128 and the black level of output
when B-BRT = 0 and 255.
Determine the level difference of non-inverted
output amplitude (white to black) of TP40, TP43,
and TP45 when SIG4 is entered to (A).
Measure the non-inverted output (white to black) of
TP45 for the non-inverted output (white to black) of
TP43 when SIG4 is entered to (A) and when
R-CNT = 0 and R-CNT = 255.
Input SIG4 to (A) and measure the difference of
the level for B-CNT = 0 and 255 from the TP40
non-inverted output (white to black) when B-CNT =
128.
Determine the difference of inverted output
amplitude for the non-inverted output amplitude
(white to black) of TP40, TP43, and TP45 when
SIG4 is entered to (A).
Determine the difference between highest and
lowest black levels for inverted and non-inverted
outputs of TP40, TP43, and TP45 when SIG4 is
entered to (A).
Enter SIG8 to (A) and set the amplitude (black to
white) of non-inverted output of TP43 to 3.5Vp-p
with CONT and set the level to 1.5V through
BRIGHT adjustment.Measure VG1, VG2, and
VG3 and calculated as follows :
GγL = 20log (VG1/0.0357)
GγM = 20log (VG2/0.0357)
GγH = 20log (VG3/0.0357) (See Fig. 5)
Enter SIG8 to (A) and set the TP43 output (black to
black) to 9Vp-p through BRIGHT adjustment.
Read the γ gain change point at γ1 = 0, γ1 = 255 by
referring to the IRE level of input signal :
Vγ1MN for γ1 = 0
Vγ1MX for γ1 = 255
Enter SIG8 to (A) and set the TP43 output (black to
black) to 9Vp-p through BRIGHT adjustment.
Read the γ gain change point at γ2 = 0, γ2 = 255 by
referring to the IRE level of input signal :
Vγ1MN for γ2 = 0
Vγ1MX for γ2 = 255
Enter SIG4 to (A) and set the output amplitude of
TP38 to 9Vp-p. Measure tPCDH for rise and
tPCDL for fall. Load : 20000pF
Enter SIG3 to (A) and measure the amplitude of
the white side limiter level of inverted/non-inverted
TP43 output.
Enter SIG3 to (A) and measure the amplitude of
the black side limiter level of inverted/non-inverted
TP43 output. VBLIMX for BLIM = 255 and VBLIMN
for BLIM = 0
Enter SIG5 (VL = 0mV) to (A) and measure the DC
voltage of TP40, TP43, and TP45.
