Switching unit


The switching unit is used in the test department for the processor controlled switching of RF signals in the frequency range DC … 8 GHz. The unit is equipped with 4 inputs and 16 outputs. Inputs 1 and 2 can be switched to outputs 1 … 8 and inputs 3 and 4 to the outputs 9 … 16. Each output is terminated by using a further relay.


The switching unit is housed in a 3 RU 19“ subrack with very good RF shielding and consists of the following sub-assemblies:

-    relays SPDT, SP8T
-    I/O boards
-    processor board
-    LAN interface and GUI

All the necessary power supply and earthing connections are provided at the rear.
The mains switch and the signal connections are  located on the front panel.


The unit is controlled via LAN interface. The graphic user interface allows the unit control and monitoring via web browser.
