To connect to "RF 50 Ω"
1. Before connecting to the "RF 50 Ω" connector on the front panel, proceed as
follows:
a) Prepare the "RF 50 Ω" connector. See "To prepare for connecting"
on page 24.
b) If activated, deactivate the RF output. In the home screen, select the block
"Level" > "RF On > Off".
If equipped with an option for rear panel connectors, prepare the "RF 50 Ω"

To prevent RF output switch-off
► NOTICE! If you set a too high output level without a load connected to the
instrument, 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.
