Electrostatic Discharge
Electrostatic discharge (ESD)
can damage or destroy electronic components. Therefore,
all work performed on assemblies consisting of electronic components should be done at a
static-free workstation. Figure l-2 is an example of a static-safe work station using two kinds
of ESD protection:
w
Conductive table mat and wrist-strap combination.
n Conductive floor mat and heel-strap combination.
These methods may be used together or separately.

Reducing Potential for ESD Damage
The suggestions that follow may help reduce ESD damage that occurs during
nstrument
testing and servicing.
w
Before connecting any coaxial cable to an analyzer connector for the first time each day,
momentarily ground the center and outer connectors of the cable.
n Personnel should be grounded with a resistor-isolated wrist strap before touching the center
in of any connector and before removing any assembly from the unit.
n Be sure all instruments are properly earth-grounded to prevent build-up of static discharge.
