Service
If the oscilloscope is under warranty, you must return it to
Hewlett-Packard for all service work covered by the warranty. See
"To return the oscilloscope to Hewlett-Packard," on page 4–4. If the
warranty period has expired, you can still return the oscilloscope to
Hewlett-Packard for all service work. Contact your nearest
Hewlett-Packard Sales Office for additional details on service work.
If the warranty period has expired and you decide to service the
oscilloscope yourself, the instructions in this chapter can help you
keep the oscilloscope operating at optimum performance.
This chapter is divided into the following four sections:
Verifying Oscilloscope Performance on page 4–5
Adjusting the Oscilloscope on page 4–27
Troubleshooting the Oscilloscope on page 4–40
Replacing Parts in the Oscilloscope on page 4–49
Service should be performed by trained service personnel only. Some
knowledge of the operating controls is helpful, and you may find it
helpful to read chapter 1, "The Oscilloscope at a Glance."
