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

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-

ToCalculateTotal Measurement Error
The digitizers accuracy specifications are expressed in the form:
( % of reading + % of range ). In addition to the reading error and range error,
you may need to add additional errors for certain operating conditions. Make
sure you apply the conditions as described in the footnotes on the specification
pages.
If you are operating the digitizer outside the temperature range specified,
apply an additional temperature coefficient error.
Understandingthe" %of reading " Error The reading error compensates for
inaccuracies that are dependent upon the input signal level. The reading error
varies according to the input level on the selected range. This error is expressed
in percent of reading. The following table shows the reading error applied to the
digitizers
±
8 V input range specification for a nominal operating temperature of
23 C 5 C.
Understandingthe" %of range" Error The range error compensates for
inaccuracies that result from the range you select. The range error contributes a
constant error, expressed as a percent of range, independent of the input signal
level. The following table shows the range error applied to the digitizers
±
8 V
input range specification for a nominal operating temperature of 23 C 5 C.
TemperatureCoefficients
Accuracy is usually specified at the calibration temperature 23 C 5 C
temperature range. This is a common temperature range for many
operating environments. You must add additional temperature coefficient
errors to the accuracy specification if you are operating the digitizer
outside the 5 C temperature range (the specification is per C).
