Switching unit


This switching unit is used for the manual and synchronous switching of 7 signals to 6 outputs each. 6 RF signals in the frequency range DC … 430 MHz and 1 RS-422 signal will be switched. The use of electrical components to control the unit is not required.


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

-    relay switch boards SP6T
-    rotary knob for manual control
-    redundant power supply

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


The unit is controlled via a rotary knob located on the front panel. All switch boards will be switched at the same time into the same position. A OFF position will be selectable also.

Special features

The unit is constructed using a modular approach utilising 19” plug-in sub-assemblies which enable ease of installation and maintenance.
