Class A.

Radiated Immunity When tested at 3 V/m accord-

ing to IEC 801-3/1984, the dis­played average noise level will
be within specifications over
the full immunity test frequency
range of 27 to 500 MHz, except
that at immunity test frequen­cies of 278.6 MHz ± selected
resolution bandwidth and

321.4 MHz ± selected resolu­tion bandwidth, the displayed
average noise level may be up
to –90 dBm. When the analyzer­tuned frequency is identical to
the immunity test signal fre­quency there may be signals of
up to ±90 dBm displayed on the
screen.

Electrostatic discharge In accordance with

IEC 801-2/1991, an air
discharge of up to 8 kV, or a
contact discharge of up to 4 kV,
will not cause any change
of instrument state or
measurement data. However,
discharges to center pins of
front or rear panel connectors
might cause damage to the
associated circuitry.

Agilent Technologies’ Test and Measurement
Support, Services, and Assistance

Agilent Technologies aims to maximize the value you receive,
while minimizing your risk and problems. We strive to ensure
that you get the test and measurement capabilities you paid
for and obtain the support you need. Our extensive support
resources and services can help you choose the right Agilent
products for your applications and apply them successfully.
Every instrument and system we sell has a global warranty.
Support is available for at least five years beyond the produc­tion life of the product. Two concepts underlie Agilent’s
overall support policy: “Our Promise” and “Your Advantage.”

Our Promise

“Our Promise” means your Agilent test and measurement equip­ment will meet its advertised performance and functionality.
When you are choosing new equipment, we will help you with
product information, including realistic performance specifica­tions and practical recommendations from experienced test
engineers. When you use Agilent equipment, we can verify that
it works properly, help with product operation, and provide
basic measurement assistance for the use of specified capabili­ties, at no extra cost upon request. Many self-help tools are
available.

Your Advantage

“Your Advantage” means that Agilent offers a wide range of
additional expert test and measurement services, which you
can purchase according to your unique technical and business
needs. Solve problems efficiently and gain a competitive edge
by contracting with us for calibration, extra-cost upgrades, out­of-warranty repairs, and on-site education and training, as well
as design, system integration, project management, and other
professional services. Experienced Agilent engineers and tech­nicians worldwide can help you maximize your productivity,
optimize the return on investment of your Agilent instruments
and systems, and obtain dependable measurement accuracy
for the life of those products.

By internet, phone, or fax, get assistance with all your
test and measurement needs.
