Installing theInstrument
Beforeconnectingtopower,check the
followingtoensureit iscorrect for your
application.
•LineCord
TheAgilent L4532A/ 34A power supply
operatesinthefollowingline-voltage
ranges:
~Line:
100-240V,50-60Hz
(240VA Max)
Noline-voltageswitch isrequiredandthe
internal line fuseis appropriatefor all volt-
ageswithintheseranges.Thisfuseisnot
user accessible.
Ensurethat thefront-panel power switch
isreadilyaccessibleduringoperations.
Theinstrument isventilatedfromthe
front,rear,andleft side.Donot obstruct
theventilation holesinanyof theseloca-
tions.
Beforeconnectingaloador deviceunder
test,readtheoperatinginstructions that
beginin chapter 1of theUser's Guide.
IntendedUseof theInstrument
TheAgilent L4532A(2-channel)or L4534A
(4-channel)20MSa/ s, Isolated/ Floating
250V, 16-bit Digitizer is intendedtobe
usedtodigitizewaveformsignalsinelec-
tronic-test applications.Each input chan-
nel providesanisolated,floatinginput
ratedfor signals of 250Vpk.Theinstru-
ment must beconnectedtothedevice
under test usingcables appropriatetothe
applicationandvoltages present.
TheL4532A/ 34Ais intendedonlyfor IEC
Measurement CategoryI applications, as
definedbelow.
IECMeasurement CategoryI
OvervoltageProtection
TheL4532A/ 34Ahas IECMeasurement
CategoryI (CATI) overvoltageprotection.
IECMeasurement CategoryI refersto
devicesthat areisolatedfromline-voltage
mains.Donot connect theinputsof aCAT
I instrument toACline-voltagemains.
W ARN I N G
Donot connect theinput channelsof
theL4532A/ 34AtoACline-voltage
mains. Thisinstrument must beused
inCATI (isolatedfrommains) appli-
cations. Donot useinother IECMea-
surement Category(CATII,CATIII,or
CATIV) applications.Failureto
observetheseprecautionsmayresult
inelectric shock andserious per-
sonal injury.
ProtectionLimits
TheAgilent L4532A/ 34Aprovides protec-
tioncircuitrytoprevent damagetothe
instrument andtoprotect against thedan-
ger of electrical shock, provided thepro-
tectionlimitsarenot exceeded.Toensure
safeoperationof theinstrument, donot
exceedtheprotection limitsshownfor
each input on therear panel.
Each input-channel BNCconnector (Chan-
