measured value

TPRO

Raise the voltage applied to 16 gradually. Represent TPRO as the

voltage at which output waveform at pin 20 is as shown below.

S/N AF

1. Measure noise within the range of 20Hz to 100kHz at output 4 .

2. S/N AF = 20 log

Vo4 max.

measured value (dB)

STH

Enter SG 17. Measure output 4 when AV SW is set to EXT

(2A=1.1V).

Iss

Increase the current of constant current source Iss. Measure a

current value of Iss when the horizontal frequency at output 20 is

pulled in from free run.

V12 min.

Increase voltage 12 from about 3V. Measure voltage 12 applied

when horizontal oscillator waveforms begin to appear at 20 (about

15kHz).

fPHL, fPHH

1. Lower the frequency of input signal SG B to make the input

waveform asynchronous to output waveform at pin 20 .

2. Raise the input frequency. Measure the frequency at the

moment when the input waveform begin to synchronize with

output waveform 20 . Define the frequency as lower pull-in

frequency fPHL.

3. Measure upper pull-in frequency fPHH in the same manner.

4. Represent the difference from reference value of 15.734kHz.

V20H, V20L, TH

V20H, V20L and TH are shown below.

At VPRO

Make sure that the voltage applied to 16 is opened and retained.

Y max.

Enter SG F. Measure the amplitude of output 22 .

GY

1. Enter SG G. Measure the amplitude of output 22 .

GY min., GY max.

1. Enter SG G. Measure the amplitude of output 22 . Define the

amplitude as VA or VB.
