Connector Care
Keeping in mind its flammable nature, a solution of pure isopropyl or ethyl alcohol
can be used to clean connectors.
CAUTION The RF connector bead deteriorates when contacted by any chlorinated or aromatic
hydrocarbon such as acetone, trichlorethane, carbon tetrachloride, and benzene.
Do not attempt to clean connectors with anything metallic such as pins or paper
clips.
Clean the connector face by first using a blast of compressed air. If the compressed
air fails to remove contaminants use a cotton swab dipped in isopropyl or ethyl
alcohol. If the swab is too big, use a round wooden toothpick wrapped in a lint free
cloth dipped in isopropyl or ethyl alcohol.
Torque
For operation to 18 GHz, the newer 8480 series power sensors have a Type-N hex
nut for tightening to the device-under-test or the power meter's 1 mW Power
Reference. Older 8480 series power sensors have a knurled portion on the
connector. Turn the connector nut (or knurled portion) only to tighten, the torque
should not exceed 135 N-cm (12 in-lb) to avoid damage to the connector.
For APC3.5 mm and 2.4mm connectors the torque should not exceed 90 N-cm (8
in-lb) to avoid damage to the connector.
CAUTION Damage can occur if torque is applied to the power sensor body.
