Test Conditions

14 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.

15 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.

16 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.

17 Input only SYNC, and after adjusting free

run, input 0.2 Vp-p

CW (

0.2 Vp-p ), then change

0.2 Vp-p

the frequency. Measure the frequency

when VCXO oscillator is placed in a locked

condition from the free-run condition.

18 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.

19 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.

21 Measure DC voltage at pin (15) when 0 V

and 4 V are applied to pin (18).

22 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.

23 The IDENT (identification) characteristics

should be not higher than the killer level.
