M8121A Maintenance
This system should be serviced only by authorized personnel.
ESD Protection
Electrostatic discharge (ESD) can damage or destroy electronic
components. All work on electronic assemblies should be performed at a
static-safe work station. The following list and figure shows an example of
a static-safe work station using two types of ESD protection. Purchase
acceptable ESD accessories from your local supplier.
•
Conductive table-mat and wrist-strap combination.
• Conductive floor-mat and heel-strap combination.
WARNING
Using controls or adjustments or performing procedures other than
those specified in the documentation supplied with your equipment can
result in hazardous radiation exposure.
CAUTION
All the connectors are very sensitive to electrostatic discharge (ESD).
There are also several exposed components on the PCAs, on both sides
of the M8121A, which can be touched accidentally while handling the
unit and can risk damage to the instrument, due to ESD. When you
connect a device or cable that is not fully discharged to these
connectors, you risk damage to the instrument and expensive instrument
repairs.
CAUTION
Electrostatic discharge (ESD) can damage the circuits of the M8121A.
Avoid applying static discharges to the front-panel connectors. Avoid
touching the front-panel connectors without first touching the frame of
the instrument. Be sure the instrument and all connected devices (DUT,
etc.) are properly earth-grounded (to a common ground) to prevent
buildup of static charge and electrical over-stress.
