Maintenance of Test Ports and Other Connectors/Ports

Test ports on the front panel of the E5070/E5071A are fitted with N Type connectors (f).
Stains or other damage to these connectors would significantly affect the accuracy in
measurements in the RF range. Always pay attention to the following precautions.
• Always keep the connectors free from stains and dust.
• Do not touch the contact surface on the connectors.
• Do not plug damaged or scratched connectors into the test ports.
• Use compressed air for cleaning connectors. Do not use abrasives under any
circumstance.
The above precautions must also be observed in maintaining connectors and ports other
than these test ports.

Cleaning a Display Other than an LCD

To remove stains on parts other than the LCD, test ports, and other connectors/ports of the
instrument, wipe them gently with a soft cloth that is dry or wetted with a small amount of
water and wrung tightly.
