Introduction
This section contains general information critical to safe and effective servic-
ing of this oscilloscope, the manual service strategy, and a description of
repair and warranty services available from Tektronix.
This manual is for servicing the TDS 410, TDS 420, & TDS 460 Digitizing
Oscilloscopes. To prevent injury to yourself or damage to the oscilloscope, do
the following before you attempt service:
H
Be sure you are a qualified service person;
H
Read the Safety Summary found at the beginning of this manual;
H
Read Strategy for Servicing and Supplying Operating Power in this sec-
tion.
When using this manual for servicing, be sure to heed all warnings, cautions,
and notes.
If servicing a TDS 410, follow the procedures for the TDS 420, but
ignore all references to CH 3 and CH 4.
Throughout this manual, any field-replaceable component, assembly,
or part of this oscilloscope is referred to generically as a module.
This manual contains all the information needed for periodic maintenance of
your oscilloscope. (Examples of such information are procedures for checking
performance and for readjustment.) Further, it contains all information for
corrective maintenance down to the module level. This means that the proce-
dures, diagrams, and other troubleshooting aids help isolate failures to a
specific module, rather than to components of that module. Once a failure is
isolated, replace the module with a fully tested module obtained from the
factory.
All modules are listed in Section 10,
Mechanical Parts List. To isolate a failure
to a module, use the fault isolation procedures found in Section 6, Mainte-
nance. To remove and replace any failed module, follow the instructions in
Removal and Installation Procedures, also found in Section 6.
