If You Have a Problem
Occasionally, a measurement may not give the expected results. If you
encounter difficulties while making measurements, use this chapter to
guide you through some possible solutions. Each heading lists a
problem you may encounter, along with some possible solutions.
If you still have difficulty using the analyzer after trying the
suggestions in this chapter, please contact your local Hewlett-Packard
service center.
CAUTION
When you are working with the analyzer, be sure to power down both the
analyzer and the target system before disconnecting or connecting cables,
probes, and preprocessors. Otherwise, you may damage circuitry in the
analyzer, preprocessor, or target system.
