LIMITED WARRANTY & LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under
normal use and service. The warranty period is one year and begins on the date of shipment.
Parts, product repairs and services are warranted for 90 days. This warranty extends only to the
original buyer or end-user customer of a Fluke authorized reseller, and does not apply to fuses,
disposable batteries or to any product which, in Fluke’s opinion, has been misused, altered,
neglected or damaged by accident or abnormal conditions of operation or handling.Fluke warrants
that software will operate substantially in accordance with its functional specifications for 90 days
and that it has been properly recorded on non-defective media. Fluke does not warrant that
software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user
customers only but have no authority to extend a greater or different warranty on behalf of Fluke.
Warranty support is available if product is purchased through a Fluke authorized sales outlet or
Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for
importation costs of repair/replacement parts when product purchased in one country is submitted
for repair in another country.
Fluke’s warranty obligation is limited, at Fluke’s option, to refund of the purchase price, free of
charge repair, or replacement of a defective product which is returned to a Fluke authorized
service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center or send the
product, with a description of the difficulty, postage and insurance prepaid (FOB Destination), to
the nearest Fluke authorized service center. Fluke assumes no risk for damage in transit.
Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB
Destination). If Fluke determines that the failure was caused by misuse, alteration, accident or
abnormal condition of operation or handling, Fluke will provide an estimate of repair costs and
obtain authorization before commencing the work. Following repair, the product will be returned to
the Buyer transportation prepaid and the Buyer will be billed for the repair and return
transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL
OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER
ARISING FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT, RELIANCE OR
ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or
exclusion or limitation of incidental or consequential damages, the limitations and exclusions of
this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or
unenforceable by a court of competent jurisdiction, such holding will not affect the validity or
enforceability of any other provision.

SafetyInformation
This Calibrator complies with IEC publication 1010-1 (1992-1), Safety Requirements for
Electrical Measuring, Control and Laboratory Equipment, and ANSI/ISA-S82.01-1994,
and CAN/CSA-C22.2 No. 1010.1-92. This manual contains information, warnings, and
cautions that must be followed to ensure safe operation and to maintain the Calibrator in
a safe condition. Use of this Calibrator in a manner not specified herein may impair the
protection provided by the Calibrator.
This Calibrator is designed for IEC 1010-1 Installation Category II use. It is not designed
for connection to circuits rated over 4800 VA.
Warning statements identify conditions or practices that could result in personal injury
or loss of life.
Caution statements identify conditions or practices that could result in damage to
equipment.
SYMBOLS MARKED ON THE CALIBRATOR
WARNING Risk of electric shock. Refer to the manual (see the Index for
references).
GROUND Ground terminal to chassis (earth).
Attention Refer to the manual (see the Index for references). This
symbol indicates that information about usage of a feature is contained in
the manual.
AC POWER SOURCE
The Calibrator is intended to operate from an ac power source that will not apply more
than 264V ac rms between the supply conductors or between either supply conductor
and ground. A protective ground connection by way of the grounding conductor in the
power cord is required for safe operation.
USE THE PROPER FUSE
To avoid fire hazard, use only the specified replacement fuse:
•For 100 V or 120 V operation, use a 5A/250V time delay fuse (Fluke PN 109215).
•For 220 V or 240 V operation, use a 2.5A/250V time delay fuse (Fluke PN 851931).
GROUNDINGTHE CALIBRATOR
The Calibrator uses controlled overvoltage techniques that require the Calibrator to be
grounded whenever normal mode or common mode ac voltages or transient voltages
may occur. The enclosure must be grounded through the grounding conductor of the
power cord, or through the rear panel CHASSIS GROUND binding post.

USE THE PROPER POWER CORD
Use only the power cord and connector appropriate for the voltage and plug
configuration in your country.
Use only a power cord that is in good condition.
Refer power cord and connector changes to qualified service personnel.
DONOT OPERATE IN EXPLOSIVE ATMOSPHERES
To avoid explosion, do not operate the Calibrator in an atmosphere of explosive gas.
CHECK INSULATIONRATINGS
Verify that the voltage applied to the unit under test does not exceed the insulation
rating of the UUT and the interconnecting cables.
DONOT REMOVE COVER DURINGOPERATION
To avoid personal injury or death, do not remove the Calibrator cover without first
removing the power source connected to the rear panel. Do not operate the Calibrator
without the cover properly installed. Normal calibration is accomplished with the cover
closed. Access procedures and the warnings for such procedures are contained in the
Service Manual. Service procedures are for qualified service personnel only.
DO NOTATTEMPTTO OPERATEIFPROTECTIONMAYBEIMPAIRED
If the Calibrator appears damaged or operates abnormally, protection may be impaired. Do
not attempt to operate the Calibrator under these conditions. Refer all questions of proper
Calibrator operation to qualified service personnel.

1-1. Introduction
The Fluke Model 5820A Oscilloscope Calibrator (Figure 1-1) is a precise instrument that
calibrates analog and digital oscilloscopes. Specifications are provided in this chapter.
Warning
To prevent electric shock or other possible injuries, the 5820A
Calibrator must be operated in the way specified by this manual
or other documentation provided by Fluke.
WCaution
Input voltages exceeding 30 V dc may cause damage to the
instrument. Do not apply voltages except in voltage
measurement mode.
Features of the 5820A Calibrator include the following:
•Automatic meter error calculation.
•%and keys that change the output value to pre-determined cardinal values
for various functions.
•Programmable entry limits that prevent invalid amounts from being entered.
•Edge, Leveled Sine, Pulse, Marker, and Wave Generation modes.
•Accurate oscilloscopic input impedance measurement.
•Tunnel Diode Pulse compatibility.
•DC Volt Measure Mode.
•Current Mode generates both DC and low frequency ac current.
•1 ns to 500 ns pulse width capability with skew controlled trigger.

1-5. 5820A Service Manual
This 5820A Service Manual includes: product specifications, appropriate theory of
operation, calibration and verification procedures, maintenance information, and options.
1-6. Specifications
The following paragraphs describe the details for the 5820A specifications. All
specifications are valid after allowing a warm-up period of 30 minutes, or twice the time
the 5820A has been turned off. (For example, if the 5820A has been turned off for 5
minutes, the warm-up period is 10 minutes.)
All specifications apply for the temperature and time period indicated. For temperatures
outside of tcal + 5 °C (tcal is the ambient temperature when the 5820A was calibrated),
the temperature coefficient is less than 0.1 times the 1-year specification per °C (limited
to 0 °C - 50 °C).
If you ordered the GHz Option, the following specification tables are supplemented by
the tables with similar headings in Chapter 5:
•Edge Specifications
•Leveled Sine Wave Specifications
Refer to Figure 1-2 for the dimensional outline of the 5820A Calibrator.
