Electrostatic Discharge Protection

Electrostatic Discharge Protection
This is important. If not properly protected against, electrostatic discharge can
seriously damage your analyzer, resulting in costly repair.
Protection against electrostatic discharge (ESD) is essential while removing
assemblies from or connecting cables 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

connection to the analyzer test port or other static-sensitive device. This
can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to
short the center conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the
cable connector.
3. Connect the other end of the cable to the test port and remove the
short from the cable.
