Preventing Electrostatic Discharge Damage

Protection against electrostatic discharge (ESD) is essential while removing
assemblies from or connecting cables and assemblies (DUT) to the network
analyzer. Static electricity can build up on your body and can easily damage
sensitive internal circuit elements when discharged. Static discharges too
small to be felt can cause permanent damage. To prevent damage to the
instrument:
— always have a grounded, conductive table mat in front of your test
— always wear a grounded wrist strap, connected to a grounded conductive
— always wear a heel strap when working in an area with a conductive floor. If
— always ground yourself before you clean, inspect, or make a connection to a
— always ground the center conductor of a test cable and DUT before making
1. Connect a short (from your calibration kit) to one end of the cable and DUT
