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 only 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 to obtain return authorization information, then
send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination).
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 failure was caused by neglect, misuse, contamination, alteration, accident,

INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY
CAUSE OR 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 or other decision-maker of competent jurisdiction, such holding will not

Protection Class I:
The instrument must be operated with a Protective Earth/
Ground connected via the power cable's protective earth/ground
conductor. The Protective Earth/Ground connects to the
instrument before the line & neutral connections when the
supply plug is inserted into the power socket on the back of the
instrument.
WARNING ANY INTERRUPTION OF THE
PROTECTIVE GROUND CONDUCTOR
INSIDE OR OUTSIDE THE INSTRUMENT
IS LIKELY TO MAKE THE INSTRUMENT
DANGEROUS.
To avoid electric shock hazard, make signal connections to the
instrument after making the protective ground connection.
Remove signal connections before removing the protective
ground connection, i.e. the power cable must be connected
whenever signal leads are connected.
Do Not Operate Without Covers
To avoid electric shock or fire hazard, do not operate the
instrument with its covers removed. The covers protect users
from live parts, and unless otherwise stated, must only be
removed by qualified service personnel for maintenance and
repair purposes.

The Power Cable and Power Supply
Disconnection
Installation Category I:
Final Width = 215mm
The intended power supply disconnect device is the ON/OFF
switch that is located on the instrument's rear panel. The ON/
OFF switch must be readily accessible while the instrument is
operating. If this operating condition cannot be met, the power
cable plug or other power disconnecting device must be readily
accessible to the operator.
To avoid electric shock and fire hazard, make sure that the power
cable is not damaged, and that it is adequately rated against
power supply network fusing. If the power cable plug is to be the
accessible disconnect device, the power cable must not be
longer than 3 metres.
Power Input & Fuse Requirements
To avoid fire hazard, use only the fuse arrangements that appear
in the fuse specification table below. Additionally, the supply
network must be fused at a maximum of 16A, and in the UK, a
10A fuse must be fitted in the power cable plug See Section 2.7
for details of setting line input voltage and changing the line
input fuse.
Power Input Fuse
Measurement and/or guard terminals are designed for connection
at Installation (Overvoltage) Category I. To avoid electric shock
or fire hazard, the instrument terminals must not be directly
connected to the AC line power supply, or to any other voltage
or current source that may (even temporarily) exceed the
instrument's peak ratings.
WARNING TO AVOID INJURY OR DEATH, DO NOT
CONNECT OR DISCONNECT SIGNAL
LEADS WHILE THEY ARE CONNECTED
TO A HAZARDOUS VOLTAGE OR
CURRENT SOURCE. MAKE SURE THAT
ALL LEADS ARE IN A SAFE CONDITION
BEFORE YOU HANDLE THEM IN ANY
WAY.
Make sure that the instrument is correctly protectively earthed
(safety grounded) via the power cable before and while any
other connection is made.

Descriptions assume 9500B/1100
1.2.2 Operating Modes
In order to be able to calibrate a wide range of different oscilloscope
parameters, flexibility is built into the design of the 9500B. Of the five
major modes only two: 'Manual' and 'Procedure', determine the everyday
front-panel use of the instrument. The other three are concerned with
system configuration, 9500B calibration and 9500B selftest.
1.2.2.1 Manual Mode
In 'Manual' Mode: the 9500B is operated entirely from the front panel.
The operator is in complete charge of the calibration procedure, usually
interpreted locally from the UUT oscilloscope manufacturer's calibration
data. Refer to Sections 3 and 4.
1.2.2.2 Procedure Mode
'Procedure' Mode involves the use of a memorized calibration procedure.
The manufacturer's data for the UUT oscilloscope will have been
interpreted into a series of calibration operations, which are programmed
on to a memory card. When the card is inserted into the 'PROCEDURE'
slot in the front panel, the 9500B will move from operation to operation,
switching the 9500B controls automatically, and issuing a series of
requests for the operator to change UUT switching and connections.
Refer to Section 5.
Portocal II v 1.7 (see paras 1.3) can be used to generate calibration
sequences on procedure cards to calibrate UUT oscilloscopes using the
Model 9500B.
1.2.2.3 Configuration Mode
This mode, requiring a password, provides access for the user-selectable
configuration options. These include:
• Set the internal reference frequency.
• Adjust the threshold for high voltage warning.
• Change the IEEE-488 bus addresses.
• Select or deselect remote emulation (SG5030 or CG5010/5011).
• Enable or disable use of an external printer (Procedure mode only).
• Set the instrument to power-up in either Manual or Procedure mode.
• Alter the passwords required for entry to Configuration and
Calibration modes.
• Select the frequency for External Reference Input.
• Set the frequency of, or disable, External Reference Output.
• Alter the memorized date and time, and its format of presentation.
• Set User language (for Procedure mode only).
• Determine the percentage of UUT measurement tolerance beyond
which a 'Borderline' result is called (in Procedure mode only).
• Enable or disable the use of a data card for 'RESULTS' (Procedure
mode only).
• Enable or disable fields in certificates to accommodate Engineer's
note (Procedure mode only).
• Select the type of certificate required to be printed, alter some of the
certificate details, and re-format its pages (Procedure mode only).
• Clear the displayed list of Procedure mode users.
1.2.2.4 Calibration Mode
Calibration of the 9500B itself cannot proceed until two security
measures have been satisfied:
1. The rear panel 'CAL' switch must be set to its 'ENABLE' position.
Note: The switch is recessed behind a small hole — at shipment this
hole is covered by a paper seal which should not be broken
except for an authorized recalibration.
A broken seal is regarded as invalidating the previous
calibration.
2. An acceptable password must be entered on the screen.
Once into Calibration mode, there are three types of calibration available.
These should be used only under supervision — if it is suspected that
calibration may be required, contact your Fluke Service Center.
•'Special' calibration, enabling automatic calibration of the main
A-D converter.
•'Factory use only' is an initial calibration which is not available to
users, requiring a second password.
•'Standard Calibration' will initiate manual calibration procedures
for those functions requiring recalibration.
Calibration of the 9500B is detailed in Section 9: 'Specification
Verification' and Section 10: 'Calibration' (Adjustment). Those 9500B
calibration sequences which are user-accessible are detailed in Section
10. If it is suspected that some other calibration may be required,
contact your Fluke Service Center.

1.2.2.5 Test Mode
Three main variants of self test are available for user initiation:
•'Base' Test: Tests the base unit only. No head data is tested.
•'Heads' Test: Tests the fitted Active Heads only, assuming that
base tests have been passed.
•'All' Test: Tests both the base unit and active heads fitted.
Note: In the above three tests, the 9500B will keep a list of all test
failures, including the number of the test and its result. Any
failures can then be recalled using screen keys.
•'Fast' Test: This is the same as the confidence test carried out
at power-on, checking power supplies, basic
operation, etc.
•'Interface' Test: This can be used to check the operation of the
display and its memory, the keyboard and/or printer
connected to the instrument. A blank memory card
inserted in either slot on the front panel can also be
tested (WARNING!: the stored contents of any
memory card subjected to this test will be overwritten!).
It is possible to print out a set of results of selftests. A printer can be
connected directly to the 25-way Centronics™ printer port on the rear
panel. The printer can be enabled from within Configuration mode.
Test procedures and error-code descriptions are given in Section 8. In
the case of a reported or suspected failure, consult your Fluke Service
Center.
1.2.3 System Operation
1.2.3.1 Remote Interface
The instrument can form part of an automated system by means of the
IEEE-488 standard digital interface. The interface has been included
both for automatic calibration of UUT oscilloscopes, and for automatic
calibration of the 9500B itself. The method of connecting to the system
controller and the IEEE-488.2 SCPI command codes are described in
Section 6.
Emulation of the SG5030 and CG5010/5011 is available only via the
remote IEEE-488 interface, as detailed in Section 6, Appendix F.
1.2.4.2 Met/Cal II
The 9500B is included in the number of calibrators accessible through
Met/Cal II which can be used to calibrate UUT oscilloscopes remotely.
1. Active Head™
At least one unit of the following products is necessary to complete the
output connection from the 9500B output channel to one channel of the
UUT oscilloscope.
Model 9510 1.1GHz Output Module (Active Head™) with 500ps
pulse edge capability.
Model 9530 3.2GHz Output Module (Active Head™) with 150ps
and 500ps pulse edge capabilities.
Model 9550 25ps Fast Edge Output Module (Active Head

Model 9560 6.4GHz Output Module (Active Head
pulse edge capability. Requires 9500-3200 or 9500B3200 base with issue 3.0 firmware or greater.
Check the last section of this manual for an Addendum that describes
any additional Active Head models.
Any one of the fitted heads can be used to provide triggers for the UUT
oscilloscope instead of signals. However, a Trigger Cable (SMC-toBNC) is shipped with the 9500B to provide triggers to a separate trigger
input on the UUT oscilloscope, with a mix of up to four active heads.
2. The following accessories are shipped with the instrument:
Pt. No. Description
401297 Current Loop Assembly for use in Current Function.
630477 Trigger Cable for trigger purposes only, in place of an

2.2 Lifting and Carrying the 9500B
Caution! The 9500B weighs in excess of 12kg, so take special
care when lifting and carrying the instrument.
2.2.1 Lifting and Carrying from Bench Height
1. Disconnect and remove any cables from the rear panel.
2. The 9500B center of gravity is concentrated at the rear. Tilt the unit
so that it is standing vertically on its rear panel, with the feet towards
you, at the edge of the bench.
3. Grasp the instrument at the bottom (rear panel) corner furthest away
from you, and tilt it slightly to rest against you. Take the weight and
carry it vertically at the same height, making sure that it remains
resting against you.
4. Place the 9500B down at the same level by setting it vertically on
to the surface, then swivel it so that it can be tilted back on to its feet.
2.2.2 Lifting and Putting Down at Low Level
1. Always bend your knees, not your back, when going down. Keep
your back as straight and as vertical as possible.
2. Use the same technique (2.2.1 - 3 above) to hold the instrument's
center of gravity close to you.
Section 2: Installing the Model 9500B 2-1
2.3 Unpacking and
Inspection
Every care is taken in the choice of packing
materials to ensure that your equipment will
reach you in perfect condition.
If the equipment has been subject to excessive
mishandling in transit, the fact will probably
be visible as external damage to the shipping
container and inner carton. In the event of
damage, the shipping container, inner carton
and cushioning material should be kept for the
carrier’s inspection.
Carefully unpack the equipment and check for
external damage to the case, sockets, controls,
etc. If the shipping container and cushioning
material are undamaged, they should be
retained for use in subsequent shipments. If
damage is found notify the carrier and your
sales representative immediately.
Standard accessories (associated products and
options) supplied with the instrument should
be as described in Section 1 and on your
delivery note.
2.4 Storage
The instrument should be stored under cover.
The shipping container provides the most
suitable receptacle for storage, as it provides
the necessary shock isolation for normal
handling operations.
Place the instrument with an active desiccant
sachet inside a sealed bag. Fit the bag into the
cushioning material inside the inner carton,
place this within the corner cushioning blocks
inside the outer shipping container, and locate
the whole package within the specified storage
environment.
2.5 Preparation for
Shipment
If the 9500B is to be transported, please consider
using the carry case, Option 60.
The instrument should be transported under
cover. The original (double) shipping container
should be used to provide shock isolation for
normal handling operations. Any other
container should be double-cushioned,
providing similar shock isolation to the
following approximate internal packing
dimensions:
Length Width Depth
Outer Box 785mm 675mm 440mm
Inner Box 675mm 565mm 315mm
Cushioned to 460mm 430mm 145mm
Place the instrument with an active desiccant
sachet inside a sealed bag. Fit the bag into the
cushioning material inside the inner carton,
place this within the corner cushioning blocks
inside the outer shipping container, and secure
the whole package.
2.6 Calibration Enable
Switch
IMPORTANT
This two-position, 'CAL' switch on the rear
panel protects the instrument calibration
memory. The instrument was initially
calibrated at the factory, so under no
circumstances should the switch be operated,
until immediate recalibration is intended.
For Recalibration:
If Calibration Mode is entered while the switch
is in the 'DISABLE' position, the following
warning message is placed on the screen:
Calibration switch not enabled!

providing an internal, passive, relay switched route for a user's external
calibration signal, via any one of five output channels to an Active
Head's BNC or PC3.5 connector .
Internal controls are provided (via front-panel keys or via the IEEE-488
/ SCPI interface) to switch the signal between channels. For further
details see Section 4, para 4.15.5 and Section 6, para 6.6.5.17.
2.8.5 Ref Frequency Input (Rear Panel)

INPUT
≤ 5Vpk
50Ω
This BNC connector is located at the middle center of the rear panel,
providing an input for a signal of good frequency accuracy, for use as
a frequency reference in the 9500B.
Internal controls are provided (via front-panel keys in Configuration
mode) to select the signal as reference. For further details see Section
3, para 3.4.3.10.
2.9 Care of Microwave Connectors
It is necessary to observe certain basic precautions when using microwave
connectors, in order to achieve accurate and repeatable calibration and
measurement results. This will also help to extend connector life.
Good practice includes:
• When not in use, ensure that connectors are kept clean. This is best
done by using a plastic endcap. Avoid touching components whose
function is to make electrical contact.
• Visually inspect all connectors, looking for dents, scratches and
metal particles. Never use damaged connectors.
• Clean connectors properly, particularly connector threads and
dielectric faces. Try compressed air first, and if this is insufficient,
use isopropyl alcohol. Avoid spillage, and never use abrasives.
• When making connections, be careful to align connectors carefully,
avoiding bending forces. Always make the initial connection
lightly to avoid cross-threading, and use a correctly-set torque
wrench for final tightening.
2.8.6 Ref Frequency Output (Rear Panel)
REF FREQUENCY

3.2 Introduction to the Front Panel
3.2.1 Local and Remote Operation
3.2.1.1 Remote, Semi-Automatic and Manual Calibration of UUT Oscilloscopes
The 9500B has been designed to present three main user interfaces for control of UUT calibration:
• Fully-automatic operation for UUT oscilloscopes which are remotely controllable on the IEEE-488 Instrumentation Control Interface,
employing IEEE-488.2/SCPI protocols. The 9500B also includes emulation modes which minimize the software effort required for
integration into existing calibration systems designed around Tektronix CG5011 and SG5030 calibrators. Refer to Section 6.
• Semi-automatic operation using procedure memory cards to drive the 9500B, with control of the subject UUT being implemented by a form
of the UUT manufacturer's procedure through a series of user prompts. Refer to Section 5.
• Manual operation from the front panel, again with control of the subject UUT being implemented by the UUT manufacturer's procedure. Refer
to Section 4.
3.2.1.2 Use of Procedure Memory Cards
This is a form of assisted (semi-automatic) calibration, in which a memory card for a specific UUT oscilloscope is inserted into PCMCIA SLOT 1.
Running Procedure Mode will generate instructions to the operator, while setting output values on the 9500B. The sequence of these instructions
and outputs, the output specifications and the pass/fail limits conform the UUT manufacturer's calibration procedure.
3.2.1.3 Manual and Remote Calibration of the 9500B Itself
The 9500B itself must periodically be verified or calibrated against suitable traceable standards. The calibration processes for the mainframe and
Active Heads are available manually, but to gain the advantages of simplicity and throughput provided by automated procedures, these process
commands are also available via the remote interface (IEEE-488.2/SCPI protocols - Section 6.). The 9500B communicates with programmable
standards under the direction of external Control Software.
3.2.1.4 General Arrangement of Front Panel Controls
The front panel is divided into three main areas:
Standby/Normal
Center: A 'Menu' and 'Output Display' LCD screen, with grouped soft keys.
Right: A control panel, used to select and adjust operational Functions and Modes, with two slots to accept memory cards.
Left: Output Connectors, used for connection of the active heads.
These features are described in the following paragraphs.
3-2 Section 3: Model 9500B Controls: Modes of Operation Descriptions assume 9500B/1100
3.2.2 Front Panel Features
3.2.2.1 Liquid Crystal Display and Screen Keys
The 9500B communicates with the operator by presenting essential information on the LCD screen. For example: the output value generally
appears in large characters below the center of the screen, accompanied by its units. An operator can move through a series of menu screens,
choosing options from those presented on the screen.
Eleven soft keys ('screen' keys) are grouped below and to the right of the screen. These are labelled by characters or symbols representing menu
choices, which appear in reserved display areas on the screen next to the keys. Main functions are selected by buttons on the 'Oscilloscope
Calibrator' panel.
3.2.2.2 'OSCILLOSCOPE CALIBRATOR' Panel
This panel carries the main controls used to select the operational functions and modes of the calibrator:
a. Major Function keys are used mainly in Manual mode (Section 4) and Calibration mode (Section 10). They are arranged down the right
edge:
: Waveform (select Square with direction, or ±DCV using screen keys).
: Sinewave (select amplitudes and frequency using screen keys and cursor controls).
: Edge (select polarity using screen keys).
: Timing Markers (select Waveform and Frequency/Period using screen keys — including Line Frequency).
Aux : Auxiliary Functions (select Current, Composite Video, Linear Ramp, Overload Pulse, UUT Input Leakage Test, Auxiliary
Input, Channel Skew, and Load Resistance or Load Capacitance measurement using screen keys).
b. Mode Key, under the Function keys. The modes are: 'Procedure', 'Manual', 'Configuration', 'Calibration' and 'Test' (refer
to sub-section 3.4).
c. Preferences Key, the bottom key. The user-preferences provided are display adjustments of: 'Screen Contrast', 'Amplitude
step' factor sequence, 'Time step' factor sequence and Deviation/UUT Error toggle (refer to sub-section 3.3).
d. OUTPUT OFF and ON keys, with an 'ON' state indicator LED, in a separate column due to their importance.
e. Alpha-numeric keypad, used for various purposes, to be described later.
f. The (Tab) key, Cursor keys and Spinwheel: These select and increment or decrement displayed quantities.
3.2.2.3 Output Connections
The ten output connectors are located on the left of the panel. Use of these connectors is described in Section 4.
3.2.2.4 PCMCIA SLOT 1 and PCMCIA SLOT 2
These slots are included mainly for Procedure mode (Section 5), although there are secondary uses.
3.2.2.5 'Standby' Push-Button
Pressing this button, in the bottom right corner of the front panel, will toggle between normal operation (LED green) and 'standby' (LED red).
The instrument will transfer automatically from normal operation to standby some 15 minutes after the most recent operation, then pressing the
button will immediately restore normal operation.
3.2.2.6 Power On/Off Switch
Line power to the 9500B is switched On and Off using a switch at the left of the instrument, on the rear panel. Up is On; Down is Off.

3.2.3 Output Controls
The aim of this discussion is to become familiar with the 9500B
interactive display, and the manipulation of front-panel controls.
We have chosen DC/Square as a typical function for manipulation (it is
also likely to be the most familiar to most new operators).
Full details of the DC/Square function are not given here, they appear
in Section 4 Subsection 4.5.
3.2.3.1 Front Panel Control Sets
We have already seen that there are two sets of front-panel controls
which manipulate the output configuration, but briefly, to establish a
base-line, here they are again:
1. Controls positioned in the right half of the front panel. They are:
a. Major Function keys, arranged in a column down the right
edge.
b. Moving left, the OUTPUT OFF and ON keys, arranged in a
separate column because of their importance.
c. Alpha-numeric Keypad.
d. Cursor Controls:
See paras 3.2.3.4.
2. Screen Soft Keys, around the display itself, are used to select subfunctions and individual parameters (identified in the areas used as
screen key labels).
Before we proceed, we need to identify the components present on a
typical menu screen. A representation of a DC/Square display in
Manual mode is given as Fig 3.2.1.
3.2.3.2 Entry to Manual Mode
This discussion is conducted in Manual mode, which you may not
recognize at present. Refer to paras 3.4.1. To enter MANUAL mode:
1. Press the front panel Mode key;
2. Press the MANUAL screen key beneath the display.
3.2.3.3 Manual Mode — Typical Menu Screen
Ensure that the 9500B is installed and switched on as in Section 2. If,
after selecting Manual mode, the display does not correspond to Fig.
3.2.1, press the
key in the top right corner of the front panel.
Familiarize yourself with Fig. 3.2.1. This is the default version of
the menu screen which will appear when you enter DC/Square
function for the first time (unless the default has been changed in
Config Mode).
N.B. Contrast inversions of symbols and fields indicate those elements
which have been selected, 'Scope Mode' (1-2-5) only in this
case.
3.2.3.4 Editing on the Screen
We have already mentioned 'Scope Mode'. This is not a major mode of
the same importance as Manual mode, but identifies a specific means
of making selections or entering changes on the screen.
In all editing, the Tab key
