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 input, use a
10X attenuator. Where possible, connect your cables to the signal source first,
and to the instrument second.
CAUTION.
To prevent damage from electrostatic discharge, install the 50
Ω
terminations on the I/O connectors when the connectors are not in use.
To prevent damage to the instrument, discharge to ground any electrostatic
charge that may be present on the center and outer conductors of cables before
attaching the cables to the instrument.
To prevent damage to the instrument, do not create an ESD antenna by leaving
cables dangling off the input with the other end open.
Always use a wrist strap when making signal connections. Wear antistatic
clothing and work in a static-free workstation.
To prevent damage to the instrument, do not apply a signal outside the Maximum
Input Voltage Swing.
For information on creating a static-controlled workstation, consult the Electron-
ic Industries Association document,

Electrostatic-Discharge-Sensitive (ESDS) Devices.
