Maintenance Information
This section contains the information needed to do periodic and corrective
maintenance on the TDS 410, TDS 420, & TDS 460 Digitizing Oscilloscopes.
Specifically, the following subsections are included:
H
Maintenance Information
— This subsection. It includes this introduc-
tion plus general information on preventing damage to internal modules
when doing maintenance.
H
Inspection and Cleaning
— Information and procedures for inspect-
ing the oscilloscope and cleaning its external and internal modules.
H
Removal and Installation Procedures
— Procedures for the remov-
al of defective modules and replacement of new or repaired modules.
Also included is a procedure for disassembly of the oscilloscope for
cleaning.
H
Troubleshooting
— Information for isolating failed modules. Included
are instructions for operating the oscilloscope internal diagnostic routines
and troubleshooting trees. Most of the trees make use of these internal
diagnostic routines to speed fault isolation to a module.
Service personnel must be prepared to safely service the oscilloscope. This
manual is for qualified service personnel only. Read the
Safety Summary at
the front of this manual. If you are unfamiliar with the operation of this oscillo-
scope, read
Operating Information before servicing the oscilloscope. To
prevent electro-static damage (ESD), read
Preventing ESD, on page 6-2,
before servicing the oscilloscope.
The following sections contain information and procedures related to doing
maintenance.
H
Section 2,
Operating Information, covers instructions useful when operat-
ing the oscilloscope in order to troubleshoot it. The section also details
the service strategy and lists options for obtaining maintenance service
and for replacing failed modules.
H
Section 3,
Theory of Operation, contains a circuit description at the
module, or block, level.
H
Section 4,
Performance Verification, contains procedures that are useful
in isolating problems to modules by testing oscilloscope performance.
H
Section 5,
Adjustment Procedures, addresses after repair adjustment and
the interval between periodic adjustments. It contains a procedure for
adjusting the internal circuits of the oscilloscope.
