Note63) The sync's amplitude of SG4 be changed all white into all black, increase from 0Vp-p to 0.03Vp-p.
Note64) The sync's amplitude of SG4 be changed all white or all black, decrease from 0.3Vp-p to 0.2Vp-p.
Note65) Measure the high voltage at SyncOUT. The measured value is treated as VSH.
Note66) Measure the low voltage at SyncOUT. The measured value is treated as VSL.
Note67) SyncOUT becomes High with sink part of SG4.
Note68) Measure the time needed for the rear edge of SG4 sink to rise from 50 % and for SyncOUT to fall
Note69) No input at the Vcc of 12V when same condition by Note2 . Measure the AC current at Vcc(5V).
Note70) The Vcc of 12V be changed all white into all black, increase from 12V to 0V.
The measured value is treated as Iccps.
Measure the DC voltage at the Vcc When no output signal at R, G and Bout.
The measured value is treated as skv.
No pulse output permitted.
Confirm no malfunction produced by noise.
Measure the time needed for the rear edge of SG4 sink to fall from 50 % and for SyncOUT to rise
from 50 % with an active prove. The measured value is treated as TDS-F ,less than 90nsec.
from 50 % with an active prove. The measured value is treated as TDS-R ,less than 90nsec.
