Conditions

When VCC = 5 V (when there is no signal),

measure sum of incoming currents at pins 29 and

24

VIN = 1.0 Vp-p video signal, use VR33 to adjust

T3 output to 0.5 Vp-p

Measure T3 output level when S9 is set to 2

Measure T3 output level when S9 is set to 4

Measure T33 DC voltage in above state

Measure T32 DC voltage in same manner

Measure T28A output level in same manner

VIN = 2.0 Vp-p video signal

Measure T3 output level

VIN = 0.5 Vp-p video signal

Measure T3 output level

VIN = 714 mVp-p LUMI, 572 mVp-p SYNC,

measure T3 SYNC level

VIN = 714 mVp-p LUMI, 143 mVp-p SYNC,

measure T3 SYNC level

VIN = 1.0 Vp-p video signal,

T26 output pulse peak value

VIN = 1.0 Vp-p video signal,

T26 output pulse width

VIN = 1.0 Vp-p video signal, measure delay time

of output SYNC versus input SYNC

Gradually attenuate the input level, measure input

level at point when output pulse width widens 1

µs or more beyond PWSYR

Measure electric potential for each of the T28

video output sync tip, pedestal, and white peak,

and assign the measured values to LSYN, LPED,

and LWHI, respectively

Measure T8 DC voltage

VIN = standard multiburst signal 1 Vp-p and S30

= off, adjust so that the 3.58 MHz component at

T21 is at a minimum

Measure the chroma level at T2 with a spectrum

analyzer, VIN = standard chroma noise test signal

1 Vp-p and S30 = off

VIN = white 50% + CW 3.0 MHz
