► NOTICE! If you set a too high output level, the reverse power can exceed a
limit forcing the R&S SMB100B to switch off the RF output.
Set an RF output level that is not higher than the maximum permissible RF
power as given in the data sheet.

Connecting to Ref In/Ref Out

The connector is located on the
To connect to "Ref In"/"Ref Out" (reference < 1 GHz)
For connection, the R&S SMB100B provides BNC connectors.

To connect to Ref In/Ref Out (reference = 1 GHz)
For connection, the R&S SMB100B provides SMA connectors.
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)"
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.
