Test Conditions
Input burst 0.2 Vp-p + CW 4.33 MHz shall
be 0 dB. Measure the output at pin (12)
when the input is changed to +4 dB and –20
dB, and calculate the ratio of the measured
amplitude to the output amplitude at 0 dB.
Input a chroma signal of 0.2 Vp-p to the
input. Reduce the amplitude and measure
the amplitude ratio when the voltage at pin
(15) exceeds 2.5 V.
Input burst 0.2 Vp-p + CW 4.33 MHz,
change V20 to 2 V, 4 V, 3 V, 1 V and 0.5 V
to measure each output (100 kHz beat)
amplitude at pin (12), and calculate the ratio
between the measured amplitude and the
output amplitude at V20 = 1 V.

Input CW 4.33 MHz of 0.2 Vp-p to the input,
and measure the output amplitude at pin
(12) when V20 = 1 V.
Input CW 4.33 MHz of 0.2 Vp-p to the input,
measure the output amplitude at pins (10),
(11) when V20 = 1 V, and calculate the ratio
of the measured amplitude to the output
amplitude in Test No.18 above.
Measure DC voltage at pin (15) when 0 V
and 4 V are applied to pin (18).

Apply B monochromatic wave 0.4 Vp-p and
burst 0.2 Vp-p to the input. Measure the
delay time from HD pulse rise to the chroma
rise of pin (12) output.
The IDENT (identification) characteristics
should be not higher than the killer level.
