Note 57) Measure the amplitude output is blanked by the SG6at OUT(29,32,35). The measured value is called
VOUT(29,32,35), and is treated as HBLK3.
Note 58) Confirm that output signal is being blanked by the SG6at the time.
Monitoring to output signal, decreasing the level of SG6. Measure the top level of SG6 when the
blanking period is disappeared. The measured value is called VthRET.
Note 59) The sync's amplitude of SG4 be changed all white into all black, increase from 0Vp-p to 0.02Vp-p.
No pulse output permitted.
Note 60) The sync's amplitude of SG4 be changed all white or all black, decrease from 0.3Vp-p to 0.2Vp-p.
Confirm no malfunction produced by noise.
Note 61) Measure the high voltage at SyncOUT. The measured value is treated as VSH.
Note 62) Measure the low voltage at SyncOUT. The measured value is treated as VSL.
Note 63) SyncOUT becomes High with sync part of SG4.
Measure the time needed for the rear edge of SG4 sync 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.
Note 64) Measure the time needed for the rear edge of SG4 sync to rise from 50 % and for SyncOUT to fall
from 50 % with an active prove. The measured value is treated as TDS-R ,less than 90nsec.
Note 65) Measure the DC voltage at D/AOUT. The measured value is ttreated as VOH.
Note 66) Measure the DC voltage at D/AOUT. The measured value is ttreated as VOL.
Note 67) Electric current flow from the output of D/AOUT must be less than 1.0 mA.
Electric current flow in the output of D/AOUT must be less than 0.4 mA.
Note 68) The difference of differential non- linearity of D/AOUT must be less than ±1.0LSB.
