Know your signal source. If it is capable of deliveringovervoltages, it is safer to
not depend on the signal source settings for protection,but instead use an
externalattenuator that protects the input from the worst-case conditions. For
example, for a 20 V maximum s ource connected to a 3 V maximum s ampling
module, use a 10X attenuator.Where possible, connect your cables to the signal
source first, and to the sampling module second.
CAUTION. Toprevent dama ge from electrostatic discharge, install 50 Ω
terminations on the sampling-module connectors beforeremoving a sampling
module froman instrument or when it is not in use. Store the sampling module in
a static-free container, such as the shipping container. Whenever you move the
sampling module from one instrument to another,use a static-free container to
transport the sampling module.
Toprevent dam age to the sampling module, discharge to ground any electrostat-
ic chargethat may be present on the center and outer conductors of cables
beforeattaching the cable to the sampling module.
Toprevent dam age to the sampling module, do not create an ESD antenna by
leaving cablesattached to the sampling-module input with the other end of the
cable open.
Toprevent dam age to the sampling module or instrument, never install or
removea sampling module when the instrument is powered-on.
Always use a wrist strap (providedwith your instrument) when handling
sampling modules or making signal connections.Wear anti-static clothing and
work in a static-freeworkstation when using sampling modules.
Use a Tektronix80A02 EOS/ESD Protection Module if doing TDR work.
Toprevent dam age to the sampling module or instrument, do not apply a voltage
outside the Maximum Input Voltage(see page 48) for your sampling module.
For information on creatinga static-controlled workstation, consult the Electron-
ic Industries Associationdocument EIA-625; Requirements for Handling
Electrostatic-Discharge-Sensitive(ESDS) Devices.
Youcan use a Tektronix 80A02 EOS/ESD Protection Module to protect the
sampling module from damagedue to static dischargefrom circuit boards and
cables. Use the 80A02 in applications wherelarge static charges can be stored on
the deviceunder test, such as when testing TDR circuit boards or cables.
Refer to thedocumentation supplied with the 80A02 module for proper
installation and use.
