T33A: 4 MHz, 300 mVp-p sine wave
T3A: 0.5 Vp-p video signal
I/O response 5H after instant when input at T33A
went to 0
With VIN = white 100% 0.5 Vp-p
Measure electric potential for each of the pin 28
video output sync tip, pedestal, and white peak,
and assign the measured values to LSYN, LPED,
and LWHI, respectively
Measure pin 28 DC voltage when 5 V is applied
to pin 26, and assign the measured value to
LVDP, and calculate the difference with LSYN
∆ VDP = LSYN – LVDP
Measure pin 28 DC voltage when 2.5 V is applied
to pin 26, and assign the measured value to
LHDP, and calculate the difference with LPED
∆HDP = LPED – LHDP
Measure pin 28 DC voltage when 1.3 V is applied
to pin 26, and assign the measured value to
LWHP, and calculate the difference with LWHI
∆WHP = LWHI – LWHP
VIN = 0.5 Vp-p video signal
