BUS CONTROLLED 3-CHANNEL VIDEO PREAMP FOR CRT DISPLAY MONITOR

SS-NV SOG input maximum noise voltage

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.

VOH D/A H output voltage

Measure the DC voltage at D/AOUT. The measured value is

treated as VOH.

SS-SV SOG minimum input voltage

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.

VSH Sync output hi level

Measure the high voltage at SyncOUT. The measured value is

treated as VSH.

VSL Sync output lo level

Measure the low voltage at SyncOUT. The measured value is

treated as VSL.

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.

VOL D/A L output voltage

Measure the DC voltage at D/AOUT. The measured value is

treated as VOL.

IAO D/A output current range

Electric current flow from the output of D/AOUT must be less than

1.0mA --- IA+.

Electric current flow into the output of D/AOUT must be more

than 0.18mA --- IA-.

DNL D/A nonlinearity

The difference of differential non-linearity of D/AOUT must be less

than ±1.0LSB.

UNI1 Uniformity characteristics1

UNI2 Uniformity characteristics2

VuniA is amplitude output at OUT (29, 32, 35), when SG6 is low

voltage. VuniB is amplitude output at OUT (29, 32, 35), when SG6

is high voltage.

moduration ratio UNI (UNI2) is calculated by the equation below;

UNI1 (UNI2)=100 • (VuniB/VuniA-1) (%)
