DSA8200 Digital Serial Analyzer and Modules Service Manual
This section contains the information needed to do periodic and corrective
maintenance on the Mainframe, Sampling Heads and Optical modules. The
following subsections are included:
Preparation. Introduction plus general information on preventing damage to
internal modules when doing maintenance.
Inspection and Cleaning. Information and procedures for inspecting the
instrument and cleaning its external and internal modules.
Removal and Installation Procedures. Procedures for the removal of
defective modules and replacement of new or repaired modules. Also
included is a procedure for disassembly of the instrument for cleaning.
Troubleshooting. Information for isolating and troubleshooting failed
modules. Included are instructions for operating the instrument's internal
diagnostic routines and troubleshooting trees. Most of the trees make use of
these internal diagnostic routines to speed fault isolation to a module.
Before servicing this product, read the Safety Summary and Introduction at the
front of the manual and the electrostatic discharge (ESD) information below.
CAUTION. Electrostatic discharge can damage any semiconductor component in
this instrument. To avoid EDS damage, always wear a grounded antistatic wrist
strap when handling the instrument.
When performing any service that requires internal access to the instrument,
adhere to the following precautions to avoid damaging internal modules and their
components due to ESD.
1. Minimize handling of static-sensitive circuit boards and components.
2. Transport and store static-sensitive modules in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
boards.
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules. Do service of static-sensitive
modules only at a static-free work station.
