TDS-F Sync output delay time1
SyncOUT becomes High with sync part of SG4.
Measure the time needed for the front 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.
TDS-R Sync output delay time2
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.

VOH D/A H output voltage
Measure the DC voltage at D/AOUT. The measured value is
ttreated as VOH.
VOL D/A L output voltage
Measure the DC voltage at D/AOUT. The measured value is
ttreated as VOL.
IAO D/A output current range
Electric current flow from the output of D/AOUT must be less than
1.0mA.
Electric current flow in the output of D/AOUT must be less than
0.4mA.
DNL D/A nonlinearity
The difference of differential non-linearity of D/AOUT must be less
than 1.0LSB.
