What You’ll Find in This Chapter
This chapter includes information on how to check for a problem with
your Agilent ESA Series Spectrum Analyzer, and how to return it for
service. It also includes descriptions of all of the analyzer built-in
messages.
Your analyzer is built to provide dependable service. However, if you
experience a problem, desire additional information, or wish to order
parts, options, or accessories, Agilent Technologies’ worldwide sales and
service organization is ready to provide the support you need.
In general, a problem can be caused by a hardware failure, a software
error, or a user error. Follow these general steps to determine the cause
and to resolve the problem.
1. Perform the quick checks listed in “Check the Basics” in this chapter.
It is possible that a quick check may eliminate your problem
altogether.
2. If the problem is a hardware problem, you have several options:
• Repair it yourself; see the “Service Options” section in this
chapter.
• Return the analyzer to Agilent Technologies for repair; if the
analyzer is still under warranty or is covered by an Agilent
Technologies maintenance contract, it will be repaired under the
terms of the warranty or plan (the warranty is at the front of this
manual).
• If the analyzer is no longer under warranty or is not covered by an
Agilent Technologies maintenance plan, Agilent Technologies will
notify you of the cost of the repair after examining the
instrument. See “How to Call Agilent Technologies” and “How to
Return Your Analyzer for Service” for more information.
WARNING No operator serviceable parts inside the analyzer. Refer
servicing to qualified personnel. To prevent electrical shock do
not remove covers.
