Connections

Good connections require a skilled operator. The most common cause of measurement error is bad connections. The following procedures illustrate how to make good connections.

CAUTION Never mate a 50 ohm connector with a 75 ohm connector. The larger center pin of a male 50 ohm connector will destroy the contact fingers of a female 75 ohm connector.

How to Make a Connection

Preliminary Connection

1.Ground yourself and all devices. Wear a grounded wrist strap and work on a grounded, conductive table mat. Refer to “Electrostatic Discharge” on page 3-2for ESD precautions.

2.Visually inspect the connectors. Refer to “Visual Inspection” on page 3-3.

3.If necessary, clean the connectors. Refer to “Cleaning Connectors” on page 3-4.

4.Carefully align the connectors. The male connector center pin must slip concentrically into the contact finger of the female connector.

5.Push the connectors straight together.

CAUTION Do not turn the device body. Only turn the connector nut. Damage to the center conductor can occur if the device body is twisted.

Do not twist or screw the connectors together. As the center conductors mate, there is usually a slight resistance.

6.The preliminary connection is tight enough when the mating plane surfaces make uniform, light contact. Do not overtighten this connection.

A connection in which the outer conductors make gentle contact at all points on both mating surfaces is sufficient. Very light finger pressure is enough to accomplish this.

7.Make sure the connectors are properly supported. Relieve any side pressure on the connection from long or heavy devices or cables.

Final Connection Using a Torque Wrench

1.Use a torque wrench to make a final connection. Table 3-1provides information about the torque wrench recommended for use with this calibration kit. A torque wrench is not included in the calibration kit. Refer to Chapter 6 for part number and ordering information.
