3.1.6.2 Test Port Maintenance
The top panel of 3943B monitoring receiver has multiple test ports. If the connection is damaged or
there is dust inside it, RF band test result may be affected. Therefore, such connector should be
maintained as follows:

Keep the connector far away from dust and keep it clean.

Do not directly contact the connector surface to prevent the electrostatic leakage (ESD).

Do not use any damaged connector.

Please use the air blower to clean the connector, and do not adopt the sandpaper and other tools to
grind the connector surface.
Port impedance matching
The radio frequency input port on the top panel of the 3943B monitoring receiver is a 50Ω connector. If
the impedance connector is not matched, the test result will be affected.

tedious steps of setting soft and hard key menus and greatly simplifies the user's operation. The front
panel of 3943B is shown in Fig. 3.10.
