Connector Removal
GPIB Connectors
These are removed by two captured screws, one on each end of the
connector; these usually can be turned by hand. Use a flathead
screwdriver if necessary.
GPIB connectors often are stacked two or three deep. When you are
removing multiple GPIB connectors, disconnect each connector one at a
time. It is a good practice to connect them back together even if you have
not yet replaced the instrument; this avoids confusion, especially if more
than one instrument has been removed.
When putting GPIB connectors back on, you must again detach them from
one another and put them on one at a time.
Precision 3.5 mm Connectors
These are precision connectors. Always use care when connecting or
disconnecting this type of connector. When reconnecting, make sure you
align the male connector properly. Carefully join the connectors, being
careful not to cross- thread them.
Loosen precision 3.5 mm connectors on flexible cables by turning the
connector nut counter- clockwise with a 5/16 inch wrench. Always
reconnect using an 8 inch- lb torque wrench (Agilent part number
8720- 1765). Semirigid cables are metal tubes, custom- formed for this
system from semirigid coax cable stock.
3.5 mm Connectors with a gold hex nut
The semirigid cables that go to the RF outputs of some devices have a gold
connector nut. These do not turn. Instead, the RF connector on the
instrument has a cylindrical connector body that turns. To disconnect this
type of connector, turn the connector body on the instrument clockwise.
This action pushes the cable’s connector out of the instrument connector.
To reconnect, align the cable with the connector on the instrument. Turn
the connector body counterclockwise. You may have to move the cable
slightly until alignment is correct for the connectors to mate. When the
two connectors are properly aligned, turning the instrument’s connector
body will pull in the semirigid cable’s connector. Tighten firmly by hand.
3.5 mm connectors with a silver hex nut
All other semirigid cable connectors use a silver- colored nut that
can
be
turned. To remove this type of connector, turn the silver nut
counter- clockwise with a 5/16 inch wrench.
