LIMITED WARRANTY AND 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, contaminated, 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 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, or abnormal condition of operation or handling, including overvoltage failures
caused by use outside the product’s specified rating, or normal wear and tear of mechanical
components, 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, 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
affect the validity or enforceability of any other provision.

Prevent Instrument Damage
Caution
To prevent possible damage to the Product or to equipment
under test:
•The front panel Head RF Output and Head Control
connectors on the Product are suited only for use with Fluke
96040A-xx Leveling Heads or the 9600FLT 1-GHz Wide
Offset Filter. Only compatible power sensors should be
connected to the front panel Sensor connectors. No other
connections are permitted.
•The Leveling Heads are fitted with close tolerance metrology
grade N-connectors compliant with MIL-C-39012 and MMC
Standards for Precision N-connectors. When used in
demanding metrology applications the Leveling Heads are
likely to be mated with similar high-quality connectors, thus,
minimizing the opportunity for wear and damage. However,
in applications that require frequent mating or mating to
lower quality connectors, the opportunity for damaging the
connectors increases. On these high-risk occasions,
consider using a sacrificial adapter to prevent damage to
the N connectors.
•Improper mating of 50 Ωand 75 Ωconnectors will cause
irreversible damage the center pin. Although appearance is
similar, the dimensions (pin diameter) of 75 Ωdiffer
significantly from those of 50 Ω. Make sure that the 50 Ω
Leveling Head is mated only to 50 Ωsystems and, likewise,
that the 75 ΩLeveling Head is mated only with 75 Ω
systems. Otherwise, mechanical damage of metrology-
grade connectors and out-of-tolerance performance is likely
to occur.

•Very high-grade flexible coaxial transmission line conducts
the RF input signal to 96040A-xx Leveling Heads. As with
any coaxial line, deformation of sidewalls or abrupt bending
can degrade performance. Take care to avoid mechanical
stress or tight bend radius < 60 mm (2.4 in).
•Critical connector mating dimensions could be damaged
during disassembly of a Leveling Head. DO NOT TAMPER with
the four mounting screws at the base of the N-Connector.
Leveling Head disassembly should only be performed by
qualified service personnel at a Fluke Service Center.
•The optional power sensor(s) contain components which
can be destroyed by electrostatic discharges. To prevent
this, never touch the sensor RF connector inner conductor
and never open the sensor. Never exceed the sensor
maximum RF power limit. Even brief overloads can destroy
the sensor.
•Reliable and repeatable RF interconnections are achieved
only at specified torque settings. Performance will be
impaired if torque settings are not observed, and permanent
connector damage is likely to result from over-tightening.
•To prevent damage to the Product, do not use aromatic
hydrocarbons or chlorinated solvents for cleaning.
•To prevent the public transmission of an unintentional RF signal,
never connect the Product output to an antenna outside a shielded
room.

Instrument Description
The Instruments are RF Reference instruments designed to create and measure the
signals necessary for precision RF and microwave applications. The 96040A model
provides outputs up to 4 GHz. See Figure 1-1. The 96270A provides outputs up to
27 GHz and includes integrated power meter readout capability. See Figure 1-2. Signal
delivery that uses interchangeable Leveling Heads from 1 mHz to 4 GHz in both models
ensures a unique combination of level accuracy, dynamic range, and frequency
coverage in both 50 and 75 systems. The 96270A model adds frequency coverage
from 1 mHz up to 27 GHz delivered with the 50 microwave output directly or optionally
via a splitter and power sensor combination. In all cases, the actual signal level delivered
to the UUT (Unit Under Test) at the selected output is set and shown directly at the
Instrument front panel or remote interface.
The subsequent list of features let you integrate the Instrument into a typical RF
calibration system:
•Accurate level / attenuation over a wide dynamic range
•Precision internal AM/FM modulation, including External Modulation capability
•Frequency Range includes LF, RF, and microwave
•High signal purity with no additional filtering, and extremely low phase noise and
jitter
•Leveling Heads to ensure direct and precise signal delivery to the load
•Integrated dual channel power meter readout (96270A).
•USB port for profile data transfer (only supports memory stick, not available on
96040A.)
•Integrated 300 MHz Frequency Counter (50 MHz in 96040A)
•IEEE 488 Remote Interface
•Remote command emulation of the 9640A RF Reference Source and some other
signal generators
•Rack Mount Slide Kit (optional)
•1 GHz Wide Offset Phase Noise Filter (optional)
