Daily Maintenance
This section provides the maintenance information for the E5070B/E5071B and describes
the self-test function (which checks the instrument for failure). This section also provides
information required for shipping the E5070B/E5071B due to breakdown or other
problem.
Cleaning Method
To clean the surface of the E5070B/E5071B, wipe the surface gently with a dry cloth or
soft cloth dampened with water and wrung dry. Never attempt to clean the inside of the
instrument.
WARNING
To avoid an electric shock, always disconnect the power cord of the E5070B/E5071B
from the power outlet when cleaning.
NOTE
To clean a touch screen type LCD (Option 016), do not wet the cloth with water.
Occasionally, a few pixels may appear on the screen as a fixed point of blue, green or red.
Please note that this is not a failure and does not affect the performance of your product.
Maintaining an N-type Connector on Each Port
Each port on the front panel of the E5070B/E5071B has an N-type connector (female). In
the RF band, soil or damage on the connector or cable will affect the measurements. The
following describes how to handle and maintain these N-type connectors.
•
The connectors should always be kept clean and away from dirt.
•
To prevent the electrostatic discharge (ESD), do not touch the contact face of the
connector.
•
Never attempt to use a damaged or nicked connector.
•
When cleaning, blow air on the connector. Never attempt to use abrasives such as
emery paper.
Each port on the front panel of the E5070B/E5071B is a 50 Ω-based N-type connector
NOTE
(female). Note that use of an N-type connector for 75 Ω cables will result in an electrical
contact failure.
Self-test When Turning on the Power
When the power is turned on, the E5070B/E5071B automatically performs a self-test. If
any error is detected by the self-test at power-on, the error message "Power on test fail"
appears in the instrument status bar. This causes the E5070B/E5071B to enter the service
mode. When being in the service mode, ship the E5070B/E5071B to the nearest Agilent
Technologies Service Center by seeing Section "Considerations When Shipping to a
