Measurement conditions

SW2 ; B T2 ; SG4

Adjust V46 so that T33 amplitude is 8V,

and adjust V43 so that T33 sine wave

amplitude is 5VP-P. Then measure the

difference between T33 and T29, 31

signals 1MHz spectrum. Measure in the

same way for G B,R and B R, G.

SW2~4 ; B, T2~4 ; SG4, V46=0.5V

Measure T29, 31 and 33 signals.

SW2~4, 43 ; B, T2~4 ; SG4, V43=4.5V

Adjust V46 so that T29, 31 and 33

amplitude is 9V and measure T29, 31 and

33 sine wave amplitude.

Adjust V46 so that T29, 31 and 33 amplitude is

0V and measure T29, 31 and 33 DC voltage.

Adjust V46 so that T29, 31 and 33 amplitude

is 0V and measure the difference T29, 31 and

33 DC voltage when V35=5V and 8v

Measure the difference between T29, 31 and 33

signal clamp levels when V46=0.5V and 4.5V.

Adjust V46 so that T31 amplitude is 5.7V

and measure T29 and 33 amplitude ratio.

After adjusting V46 so that T29, 31 and 33

amplitude is 6V, with SW21 and 42 : B, vary

V21 and 42 between 8~10V and measure

the maximum value of the difference

between T31 and T29, 33 amplitudes.

SW2~4, 29, 31, 33 ; B, T2~4 ; SG4

Adjust V46 so that T29, 31 and 33

amplitude is 8V, then adjust V43 so that

T29, 31 and 33 sine wave amplitude is

5VP-P. Vary sine wave frequency at

measure cutoff frequency.

Measure T27 amplitude.

SW28 ; B, V28=12V Measure T27 amplitude.

SW28 ; B, V28=0V T27 amplitude.

SW22, 28 ; B, V22=5V, V28=0V

Measure T27 amplitude.

SW22, 28 ; B, V22=0.5V, V28=0V

Measure T27 DC voltage

Increase current flowing out on T10, and

measure outflow current when T14

voltage changes from high to low.

Measure T14 voltage when 5V is applied to T10.

Measure T14 inverted input voltage when

T16 voltage is changed from 0 5V.

SW16 ; B Apply 0V to T16 and measure I16.

SW19, 45, 46 ; B

Measure I19 and 45 when V19 and 45 are

0.5V and 4.5V.
