Instrument Maintenance
Protecting Against Overpowering
The input circuitry of the test platform can be damaged by applying signals
that exceed the maximum safe input level of +27 dBm average total power or
+/- 30 VDC. Repairing damage to the input circuitry can be expensive. If the
test platform will be used to measure signals which might be near the
maximum safe input level, use external attenuators and/or limiters to help
protect the test platform input. Always use the three-prong AC power cord
supplied with this product. Failure to ensure adequate earth grounding by not
using this cord can cause product damage.
Cleaning the Instrument
Cleaning the Connectors
Cleaning connectors with alcohol shall only be done with the instrument power
cord removed, and in a well-ventilated area. Allow all residual alcohol moisture
to evaporate, and the fumes to dissipate prior to energizing the instrument.
Protecting against electrostatic discharge
Electrostatic discharge (ESD) can damage or destroy electronic components
(the possibility of unseen damage caused by ESD is present whenever
components are transported, stored, or used).
Test equipment and ESD
— Before connecting any coaxial cable to a test platform connector for the
first time each day, momentarily short the center and outer conductors of
the cable together.
— Personnel should be grounded with a 1
M
Ω
resistor-isolated wrist-strap
before touching the center pin of any connector and before removing any
assembly from the test platform.
To prevent electrical shock, disconnect the Keysight Technologies Model
E7515B from mains before cleaning. Use a dry cloth or one slightly dampened
with water to clean the external case parts. Do not attempt to clean internally.
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly
closed container. It is extremely flammable. In case of fire, use alcohol foam, dry
chemical, or carbon dioxide; water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact with eyes,
skin, and clothing. It causes skin irritation, may cause eye damage, and is
harmful if swallowed or inhaled. It may be harmful if absorbed through the skin.
Wash thoroughly after handling. In case of spill, soak up with sand or earth.
Flush spill area with water. Dispose of isopropyl alcohol in accordance with all
applicable federal, state, and local environmental regulations.
