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 SMA100B to switch off
the RF output.
Connect a load with sufficient return loss as given in the data sheet.
3.1.10 Connecting to Ref In/Ref Out
The connector is located on the rear panel.
To connect to Ref In/Ref Out (reference < 1 GHz)
For connection, the R&S SMA100B provides BNC connectors.
► To connect the cable with the "Ref In"/"Ref Out" connector, proceed as follows:
a) Carefully align the connector of the cable and the "Ref In"/"Ref Out" connector
along a common axis.
b) Mate the connectors along the common axis until the male pin of the connector
of the cable engages with the female socket of the "Ref In"/"Ref Out" connec-
tor.
To connect to Ref In/Ref Out (reference = 1 GHz)
For connection, the R&S SMA100B provides SMA connectors.
1. Use a high-quality cable that matches the connector type.
See "Cable selection and electromagnetic interference (EMI)" on page 29.
