Switching unit


This unit is used for the computer controlled switching of RF signals in the frequency range DC … 18 GHz.


The switching unit is housed in a 6 U 19" subrack with very good RF shielding and consists of the following sub-assemblies:

-    relay SP36T
-    control logic
-    RS-232 interface

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


The unit is controlled via a RS-232 interface.
