To connect to screwable connectors
Additional to the RF 50Ω connector, the following procedure holds for all screwable
connectors of the R&S SGS. Screwable connectors include connector types as listed
in Table 3-1.
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 22.
2.
NOTICE! Risk of instrument damage and connector damage. Excessive tightening
can damage the cables and the connectors. However, if you do not tighten the con-
nectors 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 common
axis.
b) Mate the connectors along the common axis until the male pin of the inner con-
nector 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 3-1. For more
information, see chapter "Handling" of the application note 1MA99.
3. Torque the nut to the specified limit using a calibrated torque wrench. Hold the
opposite connector part stationary with a spanner.

To prevent RF output switch-off
►
NOTICE! If you set a too high output level without a load connected to the instru-
ment, the reverse power can exceed a limit forcing the R&S SGS to switch off the
RF output.
Connect a load with sufficient return loss.
3.9 Connecting to non-screwable connectors
Non-screwable connectors of the R&S SGS are BNC type connectors on the rear
panel.
► To connect the RF cable with the RF 50Ω connector, proceed as follows:
