Operating Precautions
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
equipment.
— always wear a grounded wrist strap, connected to a grounded conductive
table mat, having a 1 M
Ω
resistor in series with it, when handling
components and assemblies or when making connections.
— always wear a heel strap when working in an area with a conductive floor. If
you are uncertain about the conductivity of your floor, wear a heel strap.
— always ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the
grounded outer shell of the test port or cable connector briefly.
— always ground the center conductor of a test cable and DUT before making
a 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 and DUT
to short the center conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable
and DUT connector.
3. Connect the other.
Most causes of instrument failure can be avoided if you will apply
the information in this section. PLEASE READ!
