Offset Control
Asyouchangethegain,thiscontrolallowsyoutoeitherkeeptheverticaloffset
levelindicatorstationary(whenDivisselected)ortohaveitmovewiththeactual
voltagelevel(whenVoltsisselected).TheadvantageofselectingDivisthatthe
waveformremainsonthegridasyouincreasethegain.IfVolt
sisselected,the
waveformcouldmoveoffthegrid.
Note:RegardlessofwhetheryouselectVoltsorDiv,theOffsetshowninthe
channelsetupdialogalwaysindicatesvolts.However,whenDivisselectedforthe
OffsetControl,theoffsetinvoltsisscaledproportionaltothechangeingain,
therebykeepingthedivisiononthegridconstant.
1. TouchUtilitiesÆPreferencesfromthemenubar.

3. UnderOffsetSettingconstantin:,toucheithertheDivorVoltsbutton.
Delay Control
Asyouchangethetimebase,thiscontrolallowsyoutoeitherkeepthehorizontal
offsetindicatorstationary(whenDivisselected)ortohaveitmovewiththetrigger
point(whenTimeisselected).TheadvantageofselectingDivisthatthetrigger
pointremainsonthegridasyouincreaseth
etimebase.IfTimeisselected,the
triggerpointcouldmoveoffthegrid.
Note:RegardlessofwhetheryouselectTimeorDiv,theDelayshowninthe
timebasesetupdialogalwaysindicatestime.However,whenDivisselectedfor
DelayIn,thedelayintimeisscaledproportionaltothechangeintimebase,thereby
keepingthedivisiononthegridconstant.
