To connect to non-screwable connectors (BNC)
► To connect the RF cable with the "RF" connector, proceed as follows:
a) Carefully align the connector of the cable and the "RF" connector along a
common axis.
b) Mate the connectors along the common axis until the male pin of the con-
nector of the cable engages with the female socket of the "RF" connector.
To connect to screwable connectors (PC 1.0/1.85/2.92/3.5 mm)
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 18.
2. NOTICE! Risk of instrument damage and connector damage. Excessive tight-
ening can damage the cables and the connectors. However, if you do not
tighten the connectors enough, the measurement results can be inaccurate.
To connect the cable with the connector, proceed as follows:
a) Carefully align the connector of the cable and the connector along a com-
mon axis.
b) Mate the connectors along the common axis until the male pin of the inner
connector engages with the female socket of the outer connector.
c) Turn the nut of the outer connector until the connectors are firmly coupled.
d) Torque the nut to the specified limit using a calibrated torque wrench. Hold
the opposite connector part stationary with a spanner.
For torque limits of the most relevant connector types, see
Table 4-1 .
3. Torque the nut to the specified limit using a calibrated torque wrench. Hold the
opposite connector part stationary with a spanner.
For more information, see chapter "Handling" of the application note 1MA99 .
If your instrument is equipped with a test port adapter, see the application note
1MA100 .
