interconnecting cables, and a user-accessible front panel enclosed in a mechani-
cal supporting frame.
This manual refers to any field-replaceable assembly or mechanical part
specifically by its name or generically as a replaceable part. In general, a
replaceable part is any circuit board or assembly, such as the hard disk drive, or a
mechanical part, such as the I/O port connectors, that is listed in the replaceable
parts list.
Symbols and terms related to safety appear in the Service Safety Summary found
at the beginning of this manual.
Related Manuals
The following manuals are available as part of the Tektronix Logic Analyzer
Family documentation set. The procedures in this manual assume that the service
