Preparation
Before servicing this product, read the Safety Summary and Introduction at the
front of the manual and the ESD information below.
CAUTION. Static discharge can damage any semiconductor component in this
generator. If you are removing a module for service, begin by doing the Access
Procedure on page 6–16. By following the instructions in that procedure, you
remove the module to be serviced while removing the minimum number of
additional modules.
When performing any service that requires internal access to the waveform
generator, adhere to the following precautions to avoid damaging internal
modules and components due to electrostatic discharge (ESD).
1. Minimize handling of static-sensitive modules.
2. Transport and store static-sensitive modules in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
modules.
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.
4. Do not allow anything capable of generating or holding a static charge on the
work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the modules over any surface.
7. Avoid handling modules in areas that have a floor or work-surface covering
capable of generating a static charge.
