4 Making Connections
34 Keysight 11923A Operating and Service Manual
Connection Procedure
1 Ground yourself and all devices (wear a grounded wrist strap and work on an antistatic mat).
2 Visually inspect the connectors (refer to “Visual Inspection” on page 27).
3 If necessary, clean the connectors (refer to “Cleaning Connectors” on page 33).
4 Carefully align the connectors. The male connector center pin must slip concentrically into the
contact fingers of the female connector (refer to Figure 4-5 and Figure 4-6 ).
5 Push the connectors straight together. Do not twist or screw them together. As the center
conductors mate, there is usually a slight resistance.
6 Initial tightening can be done by hand, or with an open-end wrench. Tighten until “snug” or
where the connectors are first making contact. The preliminary connection is tight enough
when the mating plane surfaces make uniform, light contact. Do not overtighten this
connection. At this point, all you want is for the outer conductors to make gentle contact on
both mating surfaces. Use very light finger pressure (no more than 2 in-lbs of torque).
7 Relieve any side pressure on the connection from long or heavy devices or cables. This assures
consistent torque (refer to “Using the Torque Wrench” on page 35).
CAUTION
Do not twist one connector into the other (like inserting a light bulb). This happens when you turn
the device body, rather than the connector nut. Major damage to the center conductor and the
outer conductor can occur if the device body is twisted.
