1.
Input Multi Burst signal (4.2-MHz frequency, 0.1 Vp-p at #68) of A signal in TPA. Set unicolor to maximum
(1111111), SRT-GAIN to minimum (00000), and Color detail enhancer (CDE) to minimum (00000).
2.
Set sharpness to flat (DEC [30]),
APACON peak frequency to 4.5
M (11), and monitor #12.
3.
Sine wave signal A input
becomes like signal B on #12 as
shown in the figure on the right.
Measure SA and SB.
4.
When group delay correction is
set to minimum (0000), signal A
becomes like signal C on #12.
Measure SAMIN and SBMIN.
5.
When group delay correction is
set to maximum (1111), signal A
becomes like signal D on #12.
Measure SAMAX and SBMAX.
6.
Calculate the following equations.
GAMIN = 20 × og
l
(SAMIN/SA) [dB]
GBMIN = 20 × og
l
(SBMIN/SB) [dB]
GAMAX = 20 × og

(SAMAX/SA) [dB]
GBMAX = 20 × og

(SBMAX/SB) [dB]
Note: Sine wave input starts and ends within the picture period such as a burst signal. The wave is not
continuous.
