Maintenance
This chapter contains the information needed to do periodic and corrective
maintenance on the logic analyzer.
To repair the instrument, you must exchange or replace the failed part; this
manual does not provide component-level procedures for isolating components
on the failed part.
The information in this chapter is designed for use by qualified service person-
nel. Read the Safety Summary at the front of this manual before attempting any
procedures in this chapter.
Preventing ESD
When performing any service which requires internal access to the logic
analyzer, adhere to the following precautions to avoid damaging internal circuit
boards and their components due to electrostatic discharge (ESD).
CAUTION. Many components within the chassis are susceptible to static-
discharge damage. Service the chassis only in a static-free environment.
Observe standard handling precautions for static-sensitive devices while
servicing the chassis.
Always wear a grounded w rist strap, or equivalent, while servicing the chassis.
H Minimize handling of static-sensitive circuit boards.
H Transport and store static-sensitive circuit boards in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
boards.
H Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these circuit boards. Service static-sensitive circuit
boards only at a static-free work station.
H Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
H Handle circuit boards by the edges when possible.
H Do not slide the circuit boards over any surface.
H Avoid handling circuit boards in areas that have a floor or work-surface
covering capable of generating a static charge.
