What You’ll Find in This Chapter
This chapter includes information on how to check for a problem with
your HP ESA-L1500A spectrum analyzer, and how to return it for
service. It also includes descriptions of all of the spectrum analyzer
built-in error messages.
Your spectrum analyzer is built to provide dependable service.
However, if you experience a problem, or if you desire additional
information or wish to order parts, options, or accessories,
Hewlett-Packard’s 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 spectrum analyzer to Hewlett-Packard for repair; if
the spectrum analyzer is still under warranty or is covered by an
HP 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 spectrum analyzer is no longer under warranty or is not
covered by an HP maintenance plan, Hewlett-Packard will notify
you of the cost of the repair after examining the unit. See “How to
Call Hewlett-Packard” and “How to Return Your Analyzer for
Service” for more information.
