Electrostatic Discharge; Static Controlled Workstation - Tektronix 80A05 User Manual

Getting Started

Electrostatic Discharge

To prevent electrostatic damage to the 8000 Series instrument and modules,
follow the precautions described in this manual and the manuals that come with
your instrument.
Circuitry in the module is very susceptible to damage from electrostatic
discharge or from overdrive signals. Be sure to only operate the module in a
static-controlled environment. Be sure to discharge to ground any electrostatic
charge that may be present on the center and outer connectors of cables before
attaching the cable to the module.
Know your signal source. If it is capable of delivering overvoltages, it is safer to
not depend on the signal source settings for protection, but instead use an
external attenuator that protects the input from the worst-case conditions. For
example, for a 10 V maximum source connected to a 1 V maximum module, use
a 10X attenuator. Where possible, connect your cables to the signal source first,
and to the module second.
CAUTION. To prevent damage from electrostatic discharge, install the attached
50 Ω terminations on the I/O connectors before removing the module from an
instrument, storing, or when not in use. Store the module in a static-free
container, such as the shipping container. Whenever you move the module from
one instrument to another, use a static-free container to transport the module.
To prevent damage to the module, discharge to ground any electrostatic charge
that may be present on the center and outer conductors of cables before
attaching the cables to the module.
To prevent damage to the module, do not create an ESD antenna by leaving
cables dangling off the module input with the other end open.
To prevent damage to the module or instrument, never install or remove a
module when the instrument is powered on.
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections. Wear antistatic clothing and work in a
static-free workstation when using modules.
To prevent damage to the module or instrument, do not apply a signal outside
the Maximum Input Voltage Swing for your module.

Workstation ic Industries Association document, EIA-625; Requirements for Handling
Electrostatic-Discharge-Sensitive (ESDS) Devices.
