FieldFox Analyzer Safety and Regulatory Information
Electrostatic Discharge Protection
Electrostatic Discharge Protection
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 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 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 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.
Figure 1-1 shows a typical ESD protection setup using a grounded mat and wrist strap. Refer to “ESD
Supplies” on page 6-14 for part numbers.
