instantly. Limit the number of connections and disconnections to
reduce wear and tear. Inspect connectors prior to use; look for dirt,
nicks, and other signs of damage or wear. A bad connector can ruin a
good connector instantly. Clean dirty connectors to prevent poor
electrical connections and damage to the connector. For more

Precautions for Electrostatic Discharge (ESD)

ESD can damage or destroy electronic components. Whenever possible,
conduct testing at a static-safe workstation. Keep static-generating
materials at least one meter away from all components. Before connecting
any coaxial cable to an analyzer, momentarily short the center and outer
conductors of the cable together.

Maintain working environment condition

Control your environment. Maintain temperature & humidity with a
satisfactory range within the instruments specification and prevent large
fluctuations.

Precautions for transportation

Do NOT lift the instrument with your hands at the front panel. If the
•
instrument slips, damage may occur to the keypad, knob, or input
connectors. Lift the Instrument by the handles when transporting.
Do NOT use styrene pellets as packaging materials as these may
•
cause damage to E4990A by generating static electricity.

Check for Proper Ventilation

Periodically check and clean the cooling vents of the E4990A. Inadequate
airflow can result in excessive operating temperatures which can lead to
instrument failures. When installing the product in a cabinet, the
convection in and out of the instrument must not be restricted.
