Connection of RF Cables
Apply strain relieves to the RF cables which are to be connected to the
chassis in a way, that the connectors of the device are not stressed
mechanically.
When connecting RF cables to the chassis, each connector is to be
tightened with a torque wrench adjusted to 1 Nm (141.6 ozf-in), which is the
recommended torque to be applied to 50 Ohm SMA connectors.
Note:
Best signal quality is achieved by connecting the signal receivers
symmetrically to the outputs
-
1…4 & 5…8 of a 1:8 splitter (DEV 2811, DEV 2851)
-
1…4 / 5…8 & 9…12 / 13…16 of a 1:16 splitter (DEV 2813, DEV 2853)
and
by connecting 50 Ohm SMA loads to the unused ports
If all cables are connected, the device can be powered up.
