Gain- and Gain+
Thesebuttonsincreaseordecreasethemagnificationofthecurrentlydisplayedsample
waveform,enablingyoutoseethewaveformingreaterorlesserdetail.Attheleftofthedisplay,
you’llseethemagnificationsetting,whichisexpressedindBunits.Youcanadjustthe
magnificationfrom
48dB(maximummagnification)to 0 dB.Thisdoesn’taffecttheactual

ThesimplestwaytothinkoftheZoomandGainbuttonsistorememberthattheZoombuttons
controltheleft/rightmagnificationofthewaveform,whiletheGainbuttonscontrolthe
up/

Forexample,youmightwanttozoomouttoviewan
entiresamplewaveform,todecidewhich

Zero- and Zero+
