Getting Started with Spirent TestCenter
•
Any racks or carts used for the temporary storage or transport of ESDS equipment
must be grounded either by drag chains or through direct connection to earth ground.
Loose parts that are not protected by ESD-safe packaging must not be transported on
carts.
Workstation Preparation
The ideal setup for working with ESDS equipment is a workstation designed specifically
for that purpose.
illustrates an ESD protected workstation. Please follow the
requirements listed below to prepare a proper ESD protected workstation.
•
The ESD Ground must be the equipment earth ground. Equipment earth ground is the
electrical ground (green) wire at the receptacles.
•
An ESD protected workstation consists of a table or workbench with a static
dissipative surface or mat that is connected to earth ground. A resistor in the
grounding wire is optional, providing that surface resistance to ground is
≥
10
5
to
≤
10
9
Ω.
•
The workstation must provide for the connection of a wrist strap. The wrist strap must
contain a current limiting resistor with a value from
≥
250K
Ω
to
≤
10M
Ω
.
•
ESD protective flooring or floor mats are required when floor-grounding devices (foot
straps/footwear) are used or when it is necessary to move in between ESD protected
workstations when handling ESDS equipment.

The equipment needed for proper grounding is available in ESD service kits from
various suppliers. Refer to the Buyer’s Guide on the ESDA website (
