REC ACC
characteristics (1)
ACCR1
T42A
T66
With VIN being the standard color bar signal
(1Vp-p), increase only the chroma signal level by +6dB,
measure the T66 burst level, and calculate its ratio with
VOR-66.

ACCR2
T42A
T66
With VIN being the standard color bar signal
(1Vp-p), decrease only the chroma signal level by -6dB,
measure the T66 burst level, and calculate its ratio with
VOR-66.

REC ACC killer-on
input level
VACCK-ON
T42A
T66
With VIN being the standard color bar signal
(1Vp-p), decrease the chroma signal and measure the input
burst level at which T66 output ceases. Calculate the ratio of
this value with the standard input level.

REC APC pull-in
range (1)
fAPC1
T42A
T66
Input a signal consisting of a 3.5795MHz 300mVp-p CW added
to a 50% white signal. After confirming that a signal is output
from T66, increase the CW frequency until T66 output ceases.
Now slowly reduce the CW frequency, and determine
f1 frequency at which T66 output reappears.
fAPC1 = f1-3579545 (Hz)
350
Hz
REC APC pull-in
range (2)
fAPC2
T42A
T66
As in the previous item, decrease the CW frequency until T66
output ceases.
Now slowly increase the CW frequency and determine f2
frequency at which T66 output reappears.
fAPC2 = f2-3579545 (Hz)
-350
Hz
REC AFC pull-in
range (1)
fAFC1
T42A
T60
Input a 300mVp-p, 15.7kHz, 5s width pulse train (negative
polarity).
After increasing the pulse train frequency until the T60 wave
form is disrupted, decrease the frequency to determine the f1
pulse train frequency at which the T60 wave form returns to
normal.
fAFC1 = f1-15.734 (kHz)

REC AFC pull-in
range (2)
fAFC2
T42A
T60
As in the previous item, decrease the pulse train frequency until
the T60 wave form is disrupted, then increase the frequency to
determine the f2 pulse train frequency at which the T60 wave
form returns to normal.
fAFC2 = f2-15.734 (kHz)
