To connect to screwable connectors
The R&S SMB100B provides screwable RF connectors as in Table 4-1.
► NOTICE! Excessive tightening can damage the connectors.
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) Using a calibrated torque wrench torque the nut to the limit as in the table
below. Hold the opposite connector part stationary with a spanner.

To connect to pluggable connectors
The R&S SMB100B provides pluggable Bayonet Neill-Concelman (BNC) connec-
tors.
► To connect the RF cable with the BNC connector, proceed as follows:
a) Carefully align the connector of the cable and the BNC 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 BNC connector.
For information on how to handle and maintain the RF port, to minimize measure-
ment deviations and ensure its longevity, see the application note 1MA99.
If you want to mount test port adapters to your RF connector, see the application
note 1MA100.
