Coupling
Couplingchoicesareasfollows:
• DC50Ω
• GROUND
• DC1MΩ

fromthepop‐upmenu.
Note:ThecouplingchoicesforachannelchangeifaProBusprobeisconnectedtoa
channel.
Deskew
Deskewallowsyoutocompensatefordifferentlengthsofcables,probes,or
anythingelsethatmightcausetimingmismatchesbetweensignals.Connectall
probestothedesiredchannels,thenprobeacommonsignalwitheachprobeand
adjustfortimingdifferencesusingDeskew.
ProbeAttenuation
IfyouuseaLeCroyProBuscompatibleactiveprobe,oraprobecompatiblewith
ProbeRing,theattenuationisautomaticallysetbytheoscilloscope.Ifitisnot
automaticallyset,selectavalueherebytouchinginsidetheProbeAttenfield
selectingavaluefromthepop‐upmenu.
BandwidthLimiting
Youmaysometimeswanttolimithighfrequencynoiseonaverylowbandwidth
inputsignal.Ifthisisthecase,youcanlimitthechannelbandwidthtolessthanthe
fullbandwidthoftheoscilloscope.Selectadifferentbandwidthbytouchinginside

touseaveraging,selectavalueherebytouchinginsidetheAveragingfieldand
enteringavalueupto1millionsweepsonthepop‐upkeypad.
