Test Conditions

Input standard color bar signal of VCC = 4 V.

2 Measure each output signal SYNC tip

voltage at pins (1), (7) when standard color

bar signal of 0.7 Vp-p is input.

3 Input only SYNC pulse of pulse width 4.7µs

to pin (1). Measure the output amplitude at

pin (4) when the input SYNC pulse

amplitudes are 0.2 and 0.05 Vp-p.

4 Input only SYNC pulse of pulse width 4.7µs

to pin (1). Measure the output amplitude at

pin (4) when the input SYNC pulse

amplitudes are 0.2 and 0.05 Vp-p.

5 Input only SYNC pulse of pulse width 4.7µs

to pin (1). Measure the pulse width + delay

time when the input SYNC pulse amplitudes

are 0.2 and 0.05 Vp-p.

6 Measure the frequency at which the sine

wave output amplitude is –3 dB when the

input signal (

0.2 Vp-p ) 0.2 Vp-p

is input. Also measure the output gain at

input sine wave 3.58 MHz.

7 Input standard staircase wave of 0.7 Vp-p.

Measure the output amplitude at pin (12)

when V9 is 0 V.

8 Input standard staircase wave of 0.7 Vp-p.

Calculate the ratio between the output

amplitude at pin (12) and input amplitude

when V9 is 1.7 V.

9 Input standard staircase wave of 0.7 Vp-p,

and calculate the ratio of the input amplitude

to the output amplitude in Test No.8 above

when V9 is changed to 1 V, 2.5 V and 3.5 V.

10 Input 1.5 MHz sine wave of 0.2 Vp-p to the

input. Measure the output amplitude at pin

(12) when V9 is 1.7 V, and V14 is charged

to 2, 4 and 0 V and calculate the ratio

between the input resectively and the output

amplitude when V14 = 2 V.

11 Input standard staircase wave of 0.7 Vp-p

and calculate the ratio between the output

amplitudes at pin (8) and input amplitude.

12 When input SYNC pulse at 0.2 Vp-p,

measure pin (12) output pedestal offset and

calculate ratio of the offset to that when 0.7

Vp-p standard staircase is input.
