Probes

Theoscilloscopeis compatiblewith theincludedpassive probesandmost Teledyne LeCroyactiveprobes
that are ratedfortheinstrument’sbandwidth.Probespecificationsand documentation areavailableat

PassiveProbes

Thepassiveprobessupplied are matched to theinput impedance of theinstrument but mayneed further
compensation.Follow thedirectionsinthe probeinstruction manualtocompensate thefrequency
response of theprobes.

If using other passive probesthan thosesupplied,be suretoperform a low frequencycalibration before
usingthem to measuresignal. Youcan usethe signalfrom the Cal Out hookonthe front of the
oscilloscope.

ActiveProbes

Teledyne LeCroyoffers a variety of activeprobesforusewith youroscilloscope.Most activeprobes

Powering On/Off

Press thePowerbuttonto turn on theinstrument. The X-Stream applicationloadsautomatically
whenyouusethe Powerbutton.

Thesafest wayto power down the oscilloscopeistousetheFile >Shutdownmenuoption,which will
alwaysexecuteapropershut downprocessand preservesettings.QuicklypressingthePower button
should alsoexecute a propershut down,but holding the Powerbutton willexecute a “hard”shut down (as
ona computer),which we do not recommenddoingbecauseit doesnot allowtheoperatingsystem to
closeproperly,and setup datamay be lost. Neverpower off bypullingthe power cordfrom the socket,or
bypoweringoff aconnected power stripor batterywithout first shuttingdownproperly.

ThePower button doesnot disconnect the instrument from the ACpowersupply. The onlyway to fully
powerdowntheinstrument isto unplugthe ACpower cord.
