Dear Customer,
As of November 1, 1999, four of Hewlett-Packard’s businesses, test and measurement,
semiconductor products, health care solutions, and chemical analysis became a new company,
Agilent Technologies. Now, many of your Hewlett-Packard products and services are in the care of
Agilent Technologies.
At Agilent Technologies, we are working diligently to make this transition as smooth as possible for
you. However, as a result of this transition, the products and related documentation contained in this
shipment may be labeled with either the Hewlett-Packard name and logo, the Agilent Technologies
name and logo, or a combination of both. Information in this package may refer to Hewlett-Packard
(HP), but applies to your Agilent Technologies product. Hewlett-Packard and Agilent branded
products with the same model number are interchangeable.
Whatever logo you see, the information, products, and services come from the same reliable source.
If you have questions about Agilent Technologies products and services, please visit our website at
http://www.agilent.com.

The Frequency Offset mode allows the Measuring Receiver to keep
track of frequencies involved in the down-conversion process. This
frequency offset process is used in conjunction with an external mixer
and Local Oscillator
(LO)
to extend the frequency coverage above
1300 MHz.

Dear Customer,
As
of
November
1,
1999,
four
of
Hewlett-Packard’sbusinesses, test and measurement,
semiconductor products,health care solutions, and chemicalanalysis became a new company,
Agilent Technologies. Now, manyof your Hewlett-Packardproductsand services are in the care
of
Agilent Technologies.
At Agilent Technologies, we are working diligentlyto make this transition as smooth as possible
for
you. However, as
a
result of this transition, the products and related documentationcontained in this
shipment may be labeled with either the Hewlett-Packardnameand logo, the Agilent Technologies
name and logo, or a combination of both. Information in this package may refer to Hewlett-Packard
(HP), but applies to your Agilent Technologies product. Hewlett-Packardand Agilent branded
products with the same model number are interchangeable.
Whatever logo you see, the information, products, and servicescome from the same reliable source.
If you have questions about Agilent Technologies productsand services, please visit our website at
