1-5 Electrostatic Discharge (ESD) Prevention
All electronic devices, components, and instruments can be damaged by electrostatic discharge. It is important
to take preventative measures to protect the instrument and its internal subassemblies from electrostatic
discharge.
An ESD safe work area and proper ESD handling procedures that conform to ANSI/ESD S20.20-1999 or
ANSI/ESD S20.20-2007 is mandatory to avoid ESD damage when handling subassemblies or components
found in the ME7838 Series BB/mm-Wave Vector Network Analyzer System.

Take steps to eliminate the static charges built-up on coaxial cables prior to connecting them to the VNA
System test ports. This can be done by terminating one end of the cable with the short from the calibration kit
and then grounding the outer conductor of the connector of the cables.
