With VIN a 0.5Vp-p video signal, measure the output
pulse wave height on T28.
With VIN a 0.5Vp-p video signal, measure the output
pulse width on T28.
With VIN 0.5Vp-p video signal, measure the output
pulse wave height on T27.
With VIN a 0.5Vp-p video signal, measure the output
pulse width on T27.
With VIN a 100% white 0.5Vp-p signal, measure the
sync tip and pedestal and white levels on T29 video
output, and take these as LSYN LPED LWHT,
respectively.
Measure the T29 DC voltage with 4.7V applied to
T26, and take this to be LVDP, and compute the
difference with LSYN measured above.
∆VDP = LSYN-LVDP
