(1) Input multi-burst signal (frequency equivalent to 4.2 MHz) of signal A to TPA. Set picture mute to off
(P-MODE: Normal1 (000)), UNI-COLOR to maximum (1111111), SHR-TRACKING to SRT-GAIN minimum
(11) and CDE to minimum (00).
(2) Set PICTURE-SHARPNESS to
flat (near DEC[24]), APACON
PEAK f
0
to 5 M (11) and monitor
pin 43.
(3) Input sine wave signal A (approx.
4.2 MHz) becomes signal B on
pin 43 as shown at right.
Determine S
A
and S
B
.
(4) When Y-GROUP DELAY
CORRECTION is set to minimum
(0000), signal A becomes signal
C on pin 43. Determine S
AMIN
and S
BMIN
.
(5) When Y-GROUP DELAY
CORRECTION is set to
maximum (1111), signal A
becomes signal D on pin 43.
Determine S
